Question

Which values from the set {–8, −5, −1, 1, 2, 5} satisfy this inequality?

–8x + 9 ≥ 49

Answer 1

-8 and -5

Explanation:

Plug in -8(-8)+9>-49

64+9 is 73 and 73 is bigger than 49

Do the same and plug in each of the numbers and see if the inequality makes sense.

-8 and -5

-8(-8)+9=73>=49
-8(-5)+9=49>=49
