Question

Which graph represent the solution set of this inequality

Answer 1

Hi!

First, let me explain that open circles mean that the answer starts after or before that number. So if the answer is q < 4, the answer would be C, and not B. 

If the answer was q ≤ 4, the answer would be B, and not C. 

I hope that makes sense. Now let's solve the inequality.

Remember that whatever we do to the inequality, we have to do it to both sides. 

We need to isolate q on one side.
11q + 5 ≤ 49
Start by subtracting 5 from both sides.
11q + 5 - 5 ≤ 49 - 5
11q ≤ 44
Divide by 11 on both sides.
11q/11 ≤ 44/11
q ≤ 4

The answer is B.

Hope this helps! :)
