Answer

$v\leq-3$
1501734238

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.
