Answer

$ -1\leq y \lt 3$ The graph is shown below.

Work Step by Step

The given inequality is $\Rightarrow 5\leq 3y+8 \lt 17$ Subtract $8$ from each expression. $\Rightarrow 5-8\leq 3y+8-8 \lt 17-8$ Simplify. $\Rightarrow -3\leq 3y \lt 9$ Divide each side by $3$. $\Rightarrow \frac{-3}{3}\leq \frac{3y}{3}\lt \frac{9}{3}$ Simplify. $\Rightarrow -1\leq y \lt 3$ Hence, the solution is $ -1\leq y \lt 3$.
