Answer:
7 is B
8 is C
9 is D
Step-by-step explanation:
Hey There!
So as you can see in the first image the slope of a line that passes through the coordinates (-3,1) and (5,-7) is -1
As you can see in the second image the equation of the line that passes through the points (-2,5) and (3,15) is y=2x+9
The last one is D because the equation is a=2b-3
The statement that says a is equal to 3 LESS then TWICE B is correct cause its saying that 2b - 3 is equal to a
Answer:
The answer is <u>C.</u> 0.08x + $156.00 = r.
Step-by-step explanation:
Given:
Oprah makes $156.00 per day plus an additional 8% commission on her sales.
She sold x dollars worth.
Now, to find equation how much Oprah made in one day, r.
As. given in question:
She makes per day = $156.00.
Worth of sold =
Commision on her sales = 8%.
And one day =
Now, to get the equation Oprah made in one day:
<em>Thus, the equation is</em>
Therefore, the answer is C. 0.08x + $156.00 = r.
