Question

Which expressions are equivalent to Negative 9 (two-thirds x + 1)? Check all that apply.
Negative 9 (two-thirds x) + 9 (1)
Negative 9 (two-thirds x) minus 9 (1)
Negative 9 (two-thirds x) + 1
–6x + 1
–6x + 9
–6x – 9
A B C D E F

Answer 1

First distribute: -9[(2/3)x + 1] = -9*(2/3)x + -9*1 = -6x - 9.

So the equivalent expressions are:
- Negative 9 (two-thirds x) minus 9 (1) — (B)
- –6x – 9 — (F)
