Answer 1

Answer:

B. -1

Step-by-step explanation:

I just looked over it quickly, everything looks correct.

To see if a number is in the solution set, plug it in and see if its true:

0 - 9 > -10

-9 > -10

true

-1 - 9 > -10

-10 > -10

false

1 - 9 > -10

-8 > -10

true

2 - 9 > -10

The only solution that doesn't work is B. -1
