Answer

$x\geq-19$

Work Step by Step

$-2x+7\leq45\longrightarrow$ subtract 7 from each side $-2x+7-7\leq45-7\longrightarrow$ subtract $-2x\leq38\longrightarrow$ divide each side by -2; reverse the inequality sign $-2x\div-2\geq38\div-2\longrightarrow$ divide $x\geq-19$ Since -19 is included in the solution set, the endpoint of the graph is a solid circle.
