Answer:
8 is the slope . I got m=8 but I got confused where m came from .
The first 3 rows are proportional
because when you divide the earning by car washed they all have the same unit rate of 9.5/ to answer the second part you multiply 9.5 by 88. you'll get $836
(2(8)-12)+(12(8)(2)-10)
(16-12)+(132-10)
4+122=126
THE ANSWER WOULD BE 126 :D
Answer:
x = 7
y = -2
Step-by-step explanation:
There are 2 equations. The substitution method takes one equation and puts it into the other and solves for 1 variable. Then you take that answer and put into any one equation and solve for the other variable.
Since equation #2 is already given for y = SOMETHING, we take that something and put it into "y" of the 1st equation. Shown below:

We got x = 7
Now, we know from Equation #2, y = x - 9, so
y = x - 9
y = 7 - 9
y = -2
Hence,
y = -2
In coordinate pair, the answer is (7, -2)
