Question

Which graph represents the solution set of the inequality 11 ≤ 2x + 5 ≤ 15

Answer 1

D.

Explanation:

First, simply the inequality.

`11\leq 2x+5\leq 15\\6\leq 2x\leq 10\\3\leq x\leq 5`

Based on the simplified inequality, you are looking for a line with closed points on 3 and 5. Therefore, the answer is D.
