What is the x-intercept for function f? f(x) = −2/3x + 8
Answer:
x = 12 is the x-axis intercept
Step-by-step explanation:
'x-intercept' is short for 'x-axis intercept' <==== when the graph crosses the x axis, y = 0 so put y = 0 in the equation
y = -2/3 x + 8
0 = -2/3 x + 8
-8 = - 2/3x
x = 8 * 3/2 = 12

give your answers to 2 decimal places
Answer:
-1.47, 1.14 to 2 decimal places.
Step-by-step explanation:
3x^2 + x - 5 = 0
3(x^2 + 1/3x) - 5 = 0
Completing the square on the expression in the parentheses:
3[(x + 1/6)^2 - 1/36) - 5 = 0
3(x + 1/6)^2 - 1/12 - 5 = 0
(x + 1/6)^2 = 61/12 / 3
(x + 1/6)^2 = 61/36
(x + 1/6) = +/-√61 / 6
x = -1/6 +/- √61 / 6
x = 1.135, -1.468
Write the equation of a parabola with x-intercepts at (3, 0) and (9, 0) that
passes through the point (10, -7).
The parabola's equation is y = -x2 + 12x - 27.
A parabola is a point's location where the focus and a fixed point's distance from a fixed line, known as the directrix, are the same.
A parabola's equation is in quadratic form.
Thus, it is stated as:
Y = Ax2, Bx, and C
Located at (3, 0):
0 = a(3²) + b(3) + c
9a + 3b + c = 0 (1) (1)
Located at (9, 0):
0 = a(9²) + b(9) + c
81a + 9b + c = 0 (2) (2)
Located at (10, -7):
-7 = a(10²) + b(10) + c
100a + 10b + c = -7 (3) (3)
Equations 1, 2, and 3 are solved to yield: a = -1, b = 12, and c = -27.
Consequently, the parabola's equation is y = -x2 + 12x - 27.

Step-by-step explanation:
The triangle on the right is an equilateral triangle. This means each angle is 60 degrees.
The bottom angle which goes over both triangles is marked as a right angle (90 degrees). Given that the part of that angle in the equilateral triangle is 60 degrees, the rest of the angle (i.e. the part of the angle in the other triangle) is 30 degrees.
It is implied by the markings that the angle x = the other angle at the top (although this should be clearer). Assuming this is the case, we can use the rule that angles in a triangle sum to 180 degrees, to say that:
x + x + 30 = 180
Combine like terms, rearrange and simplify:
2x + 30 = 180
2x = 150

Step-by-step explanation:
One side of an envelope is 3 inches longer than the other side. The area of the envelope is 108 in²Determine the dimensions of the envelope.
Dimensions of envelope will be Length will be (x + 3) = (9 + 3) = 12 and Breadth will be x = 9.
Envelope can be considered as the shape of rectangle.
Rectangle has length and breath which can be considered as the sides of envelope.
Now we have given one side of envelope is 3 inches longer than the other side of envelope.
let side of envelop be x inches than other side will be (x + 3) inches.
Now we have also given that the area of envelop is 108 in².
The Area of rectangle = (length)(breadth).
let length of envelop be (x+3) as its bigger than its breadth x.
∴ Substitute area of rectangle with the area of envelope.
∴ (x + 3)(x) = 108.
∴ x² + 3x = 108.
∴ x² + 3x - 108 = 0.
∴ x² + 12x -9x - 108 = 0
∴ x(x + 12) -9(x +12) = 0
∴ (x-9) (x +12) = 0
∴ (x-9) = 0 and (x +12) = 0
∴ x = 9 and x = -12
Now as dimensions cannot be negative ∴ x = -12 is rejected.
∴ x = 9 is considered
∴ Length will be (x + 3) = (9 + 3) = 12.
∴ Breadth will be x = 9.

The fundamental guidelines and procedures to simplify any algebraic statement are as follows:By multiplying factors, remove any grouping symbols like brackets and parenthesis.
If the words contain exponents, use the exponent rule to eliminate grouping.Add or subtract like terms to combine them.
Simplify: -42 30(cubed) / 12 10 (cubed)?
By removing the denominators, convert fractions to integers.
Because the denominators of our two fractions differ, we must calculate the Least Common Denominator and rewrite our fractions using the common denominator as needed. LCD(-42/30, 12/10) = 30
Now that the denominators of our two fractions are similar, we may multiply them both by 30 to get rid of the denominators.
The final result is: -42/30: 12/10 = -42: 36
With the highest common factor, attempt to further reduce the ratio (GCF).
GCF is 6 for -42 and 36.
Divide both terms by the GCF, 6, as follows: -7 36 6 = 6; -42 6 =
By dividing both parts by the GCF = 6, the ratio -42:36 can be reduced to its smallest terms: -42:36 = -7:6.

The probability of the car encountering it's first red light on the third day, i.e., P(Y = 3) will be 0.1479
As per the question statement, assuming that "Y" denotes the number of days pass up to and including the first day on which the car encounters a red light, a traffic light at a certain intersection is green 55% of the time, yellow 10% of the time, and red 35% of the time and a car approaches this intersection once each day.
We are required to calculate the probability of the car encountering it's first red light on the third day, i.e., P(Y = 3)
Here, Probability of encountering a Red light = 0.35, since traffic light at the intersection is red 35% of the time.
And "Y" is the number of days that pass up to and including the first time the car encounters a red light, i.e.,
The distribution here is a geometric one, where
P(Y = 3)
= P(Not red light in initial 2 lights) * P(red light in third light)
= [(1 - 0.35)² * 0.35]
= 0.1479

Polynomial equations are used to encode a wide range of problems, from simple word problems to complex scientific problems. Therefore, the value of k is -7.
What are Polynomials?A polynomial is an expression in mathematics made up of coefficients and indeterminates, which are also known as variables. It can only be solved using the addition, subtraction, multiplication, and powers of positive-integer variables. For instance, x3 + 2xyz2 yz + 1 has three indeterminates. Value In both mathematics and science, polynomials are widely used. For instance, they are used to define polynomial functions, which can be found in a variety of contexts, from basic chemistry and physics to economics and social science, and they are used in calculus and numerical analysis to approximate other functions. If f(x) = 3x³ + kx- 10 , If x -2 is a factor of the given equation, then,x - 2 = 0 ⇒ x = 2, On substituting, x =2, f(x) = f (2) = 0.So, f (2) = 3(2) ³ + k2- 10 = 0⇒ 24 + 2k -10 = 0 and 2k = -14⇒ k = -14/2, so k = -7In higher mathematics, polynomials are employed to build algebraic varieties and polynomial rings, which are fundamental ideas in algebra and algebraic geometry.To learn more about Polynomials, refer to:

When comparing functions, such as Seth’s scenarios for travelling to school, will the function with the greatest initial value continue to be the greatest as time increases?
No. The pace of change affects the y-value, therefore having a higher beginning value does not guarantee it. The output may decrease if the function with the bigger beginning value has a slower rate of change.
This is further explained below.
What are functions?Generally, No. Even if the function had a higher beginning value, it does not always follow that it would always have a higher y-value. This is because the y-value also relies on the rate of change.
In conclusion, If the function with the higher beginning value has a slower rate of change, it is possible that the output may become smaller at some time in the future as a consequence of this.
