Answer
$ n\geq -4$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow -\frac{3}{4}n\leq 3$
Multiply each side by $-\frac{4}{3}$. Reverse the inequality symbol.
$\Rightarrow -\frac{4}{3}(-\frac{3}{4}n)\geq -\frac{4}{3}(3)$
Simplify.
$\Rightarrow n\geq -4$
Hence, the solution is $ n\geq -4$.
Use a close circle because $-4$ is a solution.
Shade the number line on the right side.
