Answer:
1. The answer is b ≥ 4
2. m = -11; m> -11
Step-by-step explanation:
1. solve your inequality step-by-step.
-4b + 9 ≤ -7
subtract nine from both sides.
-4b + 9-9 ≤ -7-9
-4b ≤ -16
then divide both sides by 4,
-4b/4 and -16/4,
you get: b ≥ 4
2. to solve:
2m+18>-4
subtract 18 from both sides.
2m + 18 -18 >-4 -18
= 2m>-22,
divide both sides by 2,
2m/2, -22/2
you end up with: m > -11
