C, A, B
A’s rate if change:
3
B’s rate of change:
(10 - 0) / (-2 - (-4)) = 10 / 2
5
C’s rate of change:

it's x ≤ 3 :))) I found it out after realizing what you were asking
Answer: Company B
Step-by-step explanation:
First we must calculate the area of the carpet. Variable A represents area.


So the area of the carpet is 168 square feet.
To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.

Company A charges, $462, while Company B will charge $450 for the one room.
This means Company B has the better price.
Answer:
40
Step-by-step explanation:
Let n represent the integer. Then the increase can be written as ...
n + (-12) = 28
We can add 12 to both sides of this equation:
n + (-12) + (+12) = 28 +12
n + 0 = 40 . . . . . . -12 and 12 total to zero; 28 and 12 total to 40.
n = 40
The integer is 40.
It is something that you see often. In the problem it may say what is the area of a square that is 6in by 6in. The BY represent multiplication
