Answer

$c\leq-2 $ or $c\gt 7$ The graph is shown below.

Work Step by Step

The given inequality is $\Rightarrow 4c+3\leq -5$ or $c-8 \gt -1$ Solve the first inequality. $\Rightarrow 4c+3\leq -5$ Subtract $3$ from each side. $\Rightarrow 4c+3-3\leq -5-3$ Simplify. $\Rightarrow 4c\leq -8$ Divide each side by $4$. $\Rightarrow \frac{4c}{4}\leq \frac{-8}{4}$ Simplify. $\Rightarrow c\leq -2$ Solve the second inequality. $\Rightarrow c-8\gt -1$ Add $8$ to each side. $\Rightarrow c-8+8\gt -1+8$ Simplify. $\Rightarrow c\gt 7$ Hence, the solution is $c\leq-2 $ or $c\gt 7$.
