Answer:
C
Step-by-step explanation:
y <= 2x - 2
the delimiter line is therefore
y = 2x - 2
that is true for all 4 answer options.
but the y-values must be smaller than the values in the line. so, the area right-down from the line is correct.
that leaves us with B and C.
dotted line or solid line - the difference is if the line values are included in the solution or excluded.
if the line is dotted, then the line is not included.
if the line is solid, then the line is included.
because the inequality uses "<=", the line is included.
so, the answer with the solid line is correct : C.
The perimeter of the quadrilateral is 39 centimeters. Find the length of each side.

x²-2x
The length of each side include the following:
side one = 11 cm.
side two = 7 cm.
side three = 6 cm.
side four = 15 cm.
How to calculate the perimeter of a quadrilateral?In Mathematics and Geometry, the perimeter of a quadrilateral can be calculated by summing up all of its four (4) side lengths:
Perimeter of a quadrilateral, P = AB + BC + CD + AD
By substituting the given side lengths into the formula for the perimeter of a quadrilateral, we have the following;
39 = x + 2 + x + 6 + 2x - 4 + x² - 2x
39 = 2x + 4 + x²
x² + 2x - 39 + 4 = 0
x² + 2x - 35 = 0
x² + 7x - 5x - 35 = 0
x(x + 7) - 5(x + 7) = 0
(x + 7)(x - 5) = 0
x = 5 cm.
x+6; 5 + 6 = 11 cm.
x+2; 5 + 2 = 7 cm
2x-4; 2(5) - 4 = 6 cm.
x²-2x; 5²-2(5) = 15 cm.

the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.with the sum of the first n terms of the arithmetic series formula we are able to solve it
what is arithmetic series ?
An arithmetic series is a series of numbers in which each term is obtained by adding a fixed number to the preceding term (known as the common difference). The sum of the terms in an arithmetic series can be found by multiplying the average of the first and last
In the given question,
We know that the first term of the arithmetic series is given by (2t+1) and the common difference is 3. Therefore, the nth term can be written as:
aₙ = a_1 + (n-1)d
(14r - 5) = (2t + 1) + (n-1)3
14r - 5 = 2t + 1 + 3n - 3
14r - 4 = 2t + 3n
7r - 2 = t + (3/2)n --------(1)
Now, we need to find the values of p, q, and r for the sum of the first n terms of the series, which is given by:
Sₙ = (n/2)[2a_1 + (n-1)d]
Sₙ = (n/2)[2(2t+1) + (n-1)3]
Sₙ = n(3n+4t+2)/2
We can simplify this expression by factoring out a 2 from the numerator:
Sₙ = n(3n+4t+2)/2 = (2n/2)(3n+4t+2)/2
Sₙ = (n/2)(3n+4t+2) = (3/2)n² + 2tn + n
Now, we need to write this expression in the form p(qt-1). To do this, we need to factor out (3/2):
Sₙ = (3/2)(n² + 4/3 tₙ + 2/3 n)
Sₙ = (3/2)[n² + 4/3 tₙ + (2/9)(3n)]
Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n]
Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/9)t² - (4/3)tₙ + (4/3)tₙ]
Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/3)tₙ]
Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)(3t*n)]
Now we can see that p=3/2, q=3t, and r=2/9. Therefore, the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.

For the function y=5 cos {x-(π/6)}-1
a) The average rate of change between x = π/3 to x = (2π)/3 is -15/π.b) The instantaneous rate of change at x = π/2 is approximately -4.3.How to find exact form and instantaneous rate?a) To find the average rate of change, evaluate the function at x = (2π)/3 and x = π/3, and then take the difference between the two values and divide by the difference between the two x-values:
Average rate of change = (y(2π/3) - y(π/3)) / ((2π/3) - (π/3))
First, find y(2π/3) and y(π/3).
y(2π/3) = 5 cos((2π/3) - (π/6)) - 1 = 5 cos(5π/6) - 1 = -5/2 - 1 = -7/2
y(π/3) = 5 cos((π/3) - (π/6)) - 1 = 5 cos(π/6) - 1 = 5/2 - 1 = 3/2
Plugging these values into the formula:
Average rate of change = ((-7/2) - (3/2)) / ((2π/3) - (π/3))
= -5 / (π/3)
= -15/π
Therefore, the average rate of change from x = π/3 to x = (2π)/3 is -15/π.
b) To find the instantaneous rate of change at x = π/2, take the derivative of the function and evaluate it at x = π/2.
y = 5 cos(x - (π/6)) - 1
y' = -5 sin(x - (π/6))
Plugging in x = π/2:
y'(π/2) = -5 sin(π/2 - (π/6)) = -5 sin(π/3) = -5 (√3)/2
Rounding this to the nearest tenth:
y'(π/2) ≈ -4.3
Therefore, the instantaneous rate of change at x = π/2 is approximately -4.3.

What is Polygon?A polygon is a two-dimensional geometric shape that is defined by a closed path consisting of three or more straight line segments. These line segments are called sides, and the points where they meet are called vertices. Polygons can have any number of sides, although the most common polygons are those with three (triangles), four (quadrilaterals), five (pentagons), six (hexagons), and eight (octagons) sides.
To find the coordinates of A', B', C', and D', we need to apply a 180° rotation to the coordinates of A, B, C, and D.
The general formula for a 180° rotation about the origin is:
(x', y') = (-x, -y)
Using this formula, we can find the coordinates of A', B', C', and D':
A' = (-0, -0) = (0, 0)
B' = (-2, -(-5)) = (-2, 5)
C' = (-5, -(-5)) = (-5, 5)
D' = (-3, -0) = (-3, 0)
Therefore, the coordinates of polygon A'B'C'D' are:

a. The chart is prepared below.
b. At the end of 4 years, Ross still owes his parents $1,576.92.
How to calculate interest ?To solve this problem, we need to calculate the balance of Ross's loan at the end of each year.
The balance for each year can be calculated by subtracting the yearly payment from the balance at the beginning of the year and adding the interest earned for the year.
The interest for each year is calculated by multiplying the balance at the beginning of the year by the annual interest rate of 3.2%.
Here are the steps for calculating the balance for each year:
Year 1:
Beginning balance = $2,500.00
Interest for the year = $2,500.00 x 0.032 = $80.00
Ending balance = $2,500.00 + $80.00 - $300.00 = $2,280.00
Year 2:
Beginning balance = $2,280.00
Interest for the year = $2,280.00 x 0.032 = $72.96
Ending balance = $2,280.00 + $72.96 - $300.00 = $2,052.96
Year 3:
Beginning balance = $2,052.96
Interest for the year = $2,052.96 x 0.032 = $65.76
Ending balance = $2,052.96 + $65.76 - $300.00 = $1,818.72
Year 4:
Beginning balance = $1,818.72
Interest for the year = $1,818.72 x 0.032 = $58.20
Ending balance = $1,818.72 + $58.20 - $300.00 = $1,576.92
Here's a table that shows the details:
Year ,principal ,Interest rate, interest, Payment ,annual owing
1 $2,500.00 $80.00 $300.00 $2,280.00
2 $2,280.00 $72.96 $300.00 $2,052.96

A point is moving on the graph of xy = 3. When the point is at (1, 3), its x-coordinate is increasing at a rate of 4 units per second. What is the speed of the y-coordinate at that moment and in which direction is it moving?
The speed of the y-coordinate at that moment is 12 units per second, and it is moving in the negative y-direction.
What is a graph?
In computer science and mathematics, a graph is a collection of vertices (also known as nodes or points) connected by edges (also known as links or lines).
We can start by taking the derivative of the equation xy = 3 with respect to time t:
x(dy/dt) + y(dx/dt) = 0
Now we can substitute the given information: when the point is at (1, 3), dx/dt = 4. Solving for dy/dt:
(1)(dy/dt) + (3)(4) = 0
dy/dt = -12/1 = -12 units per second
The negative sign indicates that the y-coordinate is decreasing.
So the speed of the y-coordinate at that moment is 12 units per second, and it is moving in the negative y-direction.

find three mixed numbers so that the sum is 18 and the difference between the greatest number and the least number is 5 1/5
Answer:
Step-by-step explanation:
Let's begin by assigning variables to represent the three mixed numbers. Let a be the greatest mixed number, b be the middle mixed number, and c be the least mixed number. Then we can write:
a + b + c = 18 (the sum of the three mixed numbers is 18)
a - c = 5 1/5 (the difference between the greatest and least mixed numbers is 5 1/5)
To solve for a, b, and c, we can use substitution. From the second equation, we can solve for a in terms of c:
a = c + 5 1/5
Substituting this expression for a into the first equation, we get:
(c + 5 1/5) + b + c = 18
Simplifying, we get:
2c + b = 12 4/5
Now we need to find three mixed numbers that satisfy this equation. We can start by choosing a value for c. Let's choose c = 2 1/2, which is the smallest possible value for c that will allow the mixed numbers to be non-negative. Then we can solve for b:
2c + b = 12 4/5
2(2 1/2) + b = 12 4/5
5 + b = 12 4/5
b = 7 4/5
Finally, we can solve for a using the equation a = c + 5 1/5:
a = c + 5 1/5
a = 2 1/2 + 5 1/5
a = 7 3/5
Therefore, three mixed numbers that satisfy the conditions of the problem are:
The greatest mixed number: 7 3/5
The middle mixed number: 7 4/5
The least mixed number: 2 1/2
And indeed, their sum is 18 and the difference between the greatest and least mixed numbers is 5 1/5.

If 107 people attend a concert and tickets for adults cost $3.25 while tickets for children cost $2.75 and total receipts for the concert was $317.75, how many of each went to the concert?
___adults
___children
If 107 people attend a concert, 47 adults and 60 children went to concert using substitution method.
Given,
Let A be the quantity of tickets sold to adults.
Let C be the number of tickets sold to children.
Tickets for adults cost $3.25
Tickets for children cost $2.75
Equation,
3.25A + 2.75C = 317.75
And,
107 people attend a concert.
A + C = 107
Now using the substitution method,
C = 107 - A
Substituting value of C in equation 3.25A + 2.75C = 317.75,
3.25A + 2.75(107 - A) = 317.75
3.25A + 294.25 - 2.75A = 317.75
3.25A - 2.75A = 317.75 - 294.25
0.5A = 23.5
A = [tex]\frac{23.5}{0.5}[/tex]
A = 47
Substituting the value of A in equation C = 107 - A,
C = 107 - 47
C = 60

Brandon invested $4700 at 3% interest and $1100 at 8% interest using a linear equation.
In mathematics, what exactly is a linear equation?An algebraic equation of the form y=mx+b is a linear equation. m is the slant and b is the y-capture. A "linear equation in two variables" with y and x as variables is sometimes referred to as the one above.
A linear equation is one in which a variable is raised to its first power. One example of a one variable is ax+b = 0. x is a variable and an and b are genuine numbers.
Let x represent the amount invested in the first account, which earns interest at a rate of 3%, and let y represent the amount invested in the second account, which earns interest at a rate of 8%. Since the aggregate sum contributed is $5800, we have:
x + y = 5800 The first account has earned 0.03x in interest, while the second account has earned 0.08y in interest. After one year, we have earned $229 in total interest, so we have:
We now have two equations with two unknowns: 0.03x + 0.08y = 229
We can solve for x and y using either the elimination or substitution method. x + y = 5800. In this instance, we will employ substitution.
Find a solution to the first x-equation:
x = 5800 - y
Substitute this expression for x:
0.03(5800 - y) + 0.08y = 229
174 - 0.03y + 0.08y = 229
0.05y = 55
y = 1100

The area of the composite figure in the diagram given is calculated as: C. 46 square inches.
How to Find the Area of a Composite Figure?In order to find the area of the composite figure given above, it can be decomposed into a parallelogram and a trapezoid.
Therefore:
Area of the composite figure = area of parallelogram + area of trapezoid
Area of parallelogram = base * height = 7 * 5 = 35 in.²
Area of trapezoid = 1/2 * (sum of the bases) * height = 1/2 * (3 + 8) * 2
= 1/2 * 22 = 11 in.²
Area of the composite figure = 35 + 11
= 46 square inches.

Let f be a function such that StartFraction x squared minus x Superscript 4 Baseline Over x squared EndFraction ≤ f(x) ≤ One-fourth x cubed for all –2 ≤ x ≤ 2. What is Limit of f (x) as x approaches 0?
WILL MARK BRAINLIESTPLS !!!
The limit of f(x) as x approaches 0 is 0.
How to determine the Limit of f (x) as x approaches 0As x approaches 0, we can see that both the numerator and denominator of the expression in the given inequality approach 0. Thus, we can use L'Hopital's rule to evaluate the limit.
Taking the derivative of the numerator and denominator separately, we get:
lim x→0 [(2x - 4x^3) / 2x] = lim x→0 [1 - 2x^2] = 1
lim x→0 [x^3 / 4] = 0
Since 0 ≤ f(x) ≤ 1/4x^3, we can conclude that as x approaches 0, f(x) approaches 0 (by the squeeze theorem).
Therefore, the limit of f(x) as x approaches 0 is 0.

Calcular la longitud del lado excentricidad y lado recto de la cónica 9x2 + 4y2 = 36.
The eccentricity (c) length is [tex]c = \sqrt{5}[/tex] and the length of the conic's straight side is 4.
What is the standard equation of an ellipse?[tex]\frac{x^{2} }{b^{2} } + \frac{y^{2} }{a^{2} } = 1[/tex]
We can begin by transforming the given conic equation into the standard form:
[tex]9x^2 + 4y^2 = 36[/tex]
When we divide both sides by 36, we get:
[tex]\frac{x^2}{4} + \frac{y^{2} }{9} = 1[/tex]
When we compare this to the standard form equation for an ellipse, we can see that the major axis is 2a = 6 (since [tex]a^{2}[/tex] = 9 and a = 3) and the minor axis is [tex]b^{2}[/tex] = 4 (because [tex]b^{2}[/tex] = 4 and b = 2). Thus, the eccentricity (c) length can be computed using the formula:
[tex]c^{2} = a^{2} - b^{2}[/tex]
[tex]c^{2} = 9 - 4[/tex]
c = [tex]\sqrt{5}[/tex]
To get the length of the conic's straight side, we must first determine the distance between the two vertices on the major axis. We can deduce from the equation [tex]\frac{x^2}{4} + \frac{y^{2} }{9} = 1[/tex] that We can see that the vertices' x-coordinates are 2, hence the distance between them is 4. As a result, the length of the conic's straight side is 4.

The coordinates of the midpoint of GH are M (8, 0) and the coordinates of one endpoint are H (-2, 9).
Answer:
G(18 , -9)
Step-by-step explanation:
[tex]\boxed{\bf Midpoint = \left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}[/tex]
H(-2 , 9) ⇒ [tex]x_1 = -2 \ & \ y_1=9[/tex]
[tex]\left(\dfrac{-2+y_1}{2},\dfrac{9+y_2}{2}\right)= \left(8,0 \right)[/tex]
Compare x and y co-ordiantes,
[tex]\dfrac{-2+x_2}{2}= 8 \ ; \ \dfrac{9+y_2}{2}=0[/tex]
Cross multiply,
-2 + x₂ = 16 ; 9 + y₂ = 0
x₂ = 16 +2 ; y₂ = -9
x₂ = 18

When Amella started painting, the paint can had 7/8 gallon in it. She used 3/8 gallons How much paint is left in the can?
Answer: If Amella started with 7/8 gallon of paint in the can and used 3/8 gallons, then the amount of paint left in the can can be found by subtracting the amount used from the amount started with:
Amount left = Amount started with - Amount used
Amount left = 7/8 - 3/8
Amount left = 4/8 or 1/2 gallon
Therefore, Amella has 1/2 gallon of paint left in the can.

What is a linear equation in mathematics?
A linear equation is an algebraic equation of the form y=mx+b. m is the slope and b is the y-intercept. The above is sometimes called a "linear equation in two variables" where y and x are variables.
A linear equation is an equation that raises a variable to the first power. ax+b = 0 is an example of a 1 variable. x is a variable and a and b are real numbers.
Roots : -3(mult . 2), 4(mult.2)
the function is given as
f(n) = (n + 3)² (n - 4)²
= (n + 3) (n + 3 ) ( n - 4 ) ( n - 4)
= (n² + 6n + 9) (n² - 8n + 16 )
= n⁴ - 8n³ + 16n² + 6n³ - 48n² + 96n + 9n² - 72n + 1
collecting like term,
f(n) = n⁴ - 2n³ - 23n² + 24n + 144
