Answer:
14=3x-2y
[tex]y = m x+ c \\ y = \frac{3}{2} x - 7 \\ y = \frac{3x - 14}{2} \\ 2y = 3x - 14 \\ 14 = 3x - 2y \\ therefore \\ 14 = 3x - 2y \: is \: the \: required \: eqution \: of \: the \: line[/tex]

HELP WORTH 80 points! DO PART ONE AND PART TWO!
Answer:
see explanation
Step-by-step explanation:
The area (A) is calculated as
A = 3(2x + 1) = 6x + 3
Now 12 ≤ A ≤ 36 , that is
12 ≤ 6x + 3 ( subtract 3 from both sides )
9 ≤ 6x ( divide both sides by 6 )
1.5 ≤ x
and
6x + 3 ≤ 36 ( subtract 3 from both sides )
6x ≤ 33 ( divide both sides by 6 )
x ≤ 5.5
Put the 2 results together, then
1.5 ≤ x ≤ 5.5
Substitute the end values into length = 2x + 1
x = 1.5 : length = 2(1.5) + 1 = 3 + 1 = 4
x = 5.5 : length = 2(5.5) + 1 = 11 + 1 = 12
length can be between 4 and 12

Hello!
The midpoint separates two equal distances,
This means that AB = BC
So lets type of the equation to solve for x:
2x + 7 = 5x -14
Lets add 14 on both sides.
2x + 21 = 5x
Lets subtract 2x on both sides.
21 =3x
Lets divide 3 by both sides
x = 7
AB= 21
2(7) + 7
14 + 7
21
BC = 21
5(7) - 14
35 - 14
21
AC = 42
21 + 21 = 42
I hope this helps, Have a great day!!

Solve for n in the literal equation a(n − 5) + 6 = bn.
Answer:
(6-5a)/(b-a) = n
Step-by-step explanation:
a(n − 5) + 6 = bn
Distribute
an -5a +6 = bn
Subtract an from each side
an -5a+6 -an = bn-an
6-5a = bn-an
Factor out n
6-5a = n(b-a)
Divide each side by (b-a)
(6-5a)/(b-a) = n
Answer:
[tex]a(n - 5) + 6 = bn \\ an - 5a + 6 = bn \\ an - bn = 5a - 6 \\ n(a - b) = 5a - 6 \\ n = \frac{5a - 6}{a - b} \\ thank \: you[/tex]
Find the slope of the line whose equation is 8 y = 4 − 3 x .
Answer:
-3/8
Step-by-step explanation:
8y = 4 - 3x
~Divide 8 to everything
y = 1/2 - 3/8x
~Reorder
y = -3/8x + 1/2
In slope intercept form [ y = mx + b ] m resembles the slope so -3/8 is the slope.

State the type of graph that is characteristic of velocity with depth
Graphs and functions are used to show relationships between variables.
The term "graph" as used in this question represents functions. There are several types of functions, some of them are:
LinearPowerQuadraticPolynomialThe question is incomplete, so I'll give a general explanation of how to identify the graph
Linear function:
This is represented by a straight line, and the equation is [tex]y = mx + b[/tex]
Power function
This is when a variable is raised to the power of a fixed number. It is represented as: [tex]y = x^n[/tex]
Quadratic Function
A quadratic function has the form: [tex]y = ax^2 + bx + c[/tex]
Polynomial function
A polynomial function is a function where the exponents of the variable are non-negative. The form of a polynomial function is: [tex]y = ax^m + bx^{m-1} + cx^{m-2} + ........ + d[/tex]
There are several other functions (sinusoidal, constant, inverse, rational functions, etc.)
Compare the missing graph of this question to the attached graphs (see attachment), to determine the graph type.

-2(7 + y) ≥ -8(y + 1)
Answer: y ≤ -2.2
Step-by-step explanation:
Given expression
-2 (7 + y) ≥ 8 (y + 1)
Expand parentheses and apply the distributive property
-14 - 2y ≥ 8y + 8
Subtract 8y on both sides
-14 - 2y - 8y ≥ 8y + 8 - 8y
-14 - 10y ≥ 8
Add 14 on both sides
-14 - 10y + 14 ≥ 8 + 14
-10y ≥ 22
Divide -10 on both sides
(REMEMBER to change the [≤, ≥] signs when multiplying/subtracting a negative number)
-10y / -10 ≥ 22 / -10

The elder brother has 280 yuan, and the younger brother has 56 yuan, How many times is the money of the elder brother?
Step-by-step explanation:
how many times is the money of the elder brother ?
this is the same to ask "how many times do I need to add the money of the younger brother to get the money off the older brother ?"
this is simply done by division : how many times do 56 fit into 280 ?
280 / 56 = 5
so, the elder brother has 5 times the money of the younger brother.
Answer:
56+56+56+56+56
hence
5 times

Help meeeeeee on this math hw
Answer:
Step-by-step explanation:
What do you know about y?
Nothing. It could be odd or even. You can't take the chance. So you need to start your list with 2y
That means that 2y + 2 is the second member in your list
2y + 4
2y + 6
2y + 8
2y + 10
But notice you only have 5 numbers. 2y + 10 cannot be the answer.
The answer must be 2y + 20
How many digits does the number 5^100 have if it's written in the decimal system?
please helpppppp!!!!!!!!!
Answer:
64w^2
Step-by-step explanation:
Because 8w is in parentheses, you must apply the exponent to both the 8 and w.
So, it becomes (8*8)(x*x) which equals (64)(x^2).
Which then gives you your final answer, 64x^2.
The function f(x)=100+0.75(x-50) can be used to determine the cost in dollars for printing x, t shirts what is the rate of change of the cost in dollars with respect to the number of t shirts printed
A. $100
B. -$50
C. $50
D.$0.75
Answer:
0.75$ did it on quiz 100% right
Step-by-step explanation:
The general rate of change can be found by using the difference quotient formula. To find the average rate of change over an interval, enter a function with an interval: f
(
x
)
=
x
2
,
[
2
,
3
]
0.75
We know that the function:
f(x) = 100 + 0.75×(x - 50)
Models the cost in dollars of printing x t-shirts.
We want to find the rate of change of the cost in dollars. We will find that the correct option is D: $0.75
First, remember that a general linear equation can be written as:
y = a×x + b
Where the rate of change is "a" (also called the slope)
So just let's write our function in this way, to do this, we need to distribute the multiplication in the second term:
f(x) = 100 + 0.75×(x - 50) = 100 + 0.75×x - 0.75×50 = 0.75×x + 62.5
So we can see that the rate of change is 0.75
And f(x) is expressed in dollars, thus the actual rate of change is $0.75.
Then the correct option is D: $0.75

Find the value of X in the following figures where O is the centre of the circle.
9514 1404 393
Answer:
70°55°35°35°Step-by-step explanation:
An inscribed angle is half the measure of the central angle that intercepts the same arc.
__
(i) 35° = x/2 ⇒ x = 70°
(ii) x = 110°/2 = 55°
(iii) x = 70°/2 = 35°
(iv) x = 90° -55° = 35° . . . . a triangle inscribed in a semicircle is a right triangle
Step-by-step explanation:
#1
Centre = O
x = 35 × 2
x = 70⁰
#2
Centre = O
x = 110/2
x = 55⁰
#3
Centre = O
x = 70/2
x = 35⁰
#4
Centre = O
A right angle triangle has a side of 90⁰
x = 90 - 55
x = 35
