Answer
$v\leq-3$
Work Step by Step
$-\frac{v}{2}\geq1.5\longrightarrow$ multiply each side by -2; reverse the inequality
$-\frac{v}{2}\times-2\leq1.5\times-2\longrightarrow$ multiply
$v\leq-3$
Check the endpoint.
$-\frac{-3}{2}\overset?=1.5$
$1.5=1.5\checkmark$
Check the inequality.
$-\frac{-4}{2}\overset?\geq1.5$
$2\geq1.5\checkmark$
Since -3 is included in the solution, the endpoint of the graph is a solid circle.
