Answer
$k\leq -8$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow k+5\leq -3$
Subtract $5$ from each side.
$\Rightarrow k+5-5\leq -3-5$
Simplify.
$\Rightarrow k\leq -8$
Hence, the solution is $k\leq -8$.
Use a close circle because $-8$ is a solution.
Shade the number line on the left side.
