Question

Which graph represents the solution of the inequality? ​

Answer 1

The third graph.

Explanation:

`14\leq2t+18\leq20\qquad\text{subtract 18 from all sides}\\\\14-18\leq2t+18-18\leq20-18\\\\-4\leq2t\leq2\qquad\text{divide all sides by 2}\\\\(-4)/(2)\leq(2t)/(2)\leq(2)/(2)\\\\-2\leq t\leq1\\\\\text{The third graph.}`
