Terrence Allison · Answer 1

B) x ≥ - 2

Step-by-step explanation:

We have to find a number that when subtracted 3 times from number 5 will get a result that is ≤ 11. We can make the following inequality out of what we know:

5 - 3x ≤ 11

We just have to isolate x:

5 - 3x ≤ 11

5 - 11 ≤ 3x

-6 ≤ 3x

-2 ≤ x

x ≥ - 2

And you can verify it ... by testing with

-1 ⇒ 5 - (-3) ≤ 11, 8 ≤ 11 YES

and - 3 ⇒ 5 - (-9) ≤ 11, 14 ≤ 11 NO
