Sophie: 5x – 32x² – 36x Sophie's expression is because . Salima: 5x – 4x(-x) Salima's expression is because . Yvette: x(8x – 9) Yvette's expression is because . Equivalent Expression A correct equivalent expression is .

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

table 3 represents a direct variation function. : )
