Given inequality is

$-80\leq v-3(5-4v)$

Solve the inequality:

$\begin{gathered} -80\leq v-15+12v \\ -80\leq13v-15 \\ -80+15\leq13v-15+15 \\ -65\leq13v \\ -(65)/(13)\leq(13v)/(13) \\ -5\leq v \end{gathered}$

The solution is

$-5\le v$

This means v can take the values greater than or equal to -5.

That is shade the region that is right of the -5.

The required shaded region of the solution is:
