Answer

$h\gt-13$

Work Step by Step

$-5h\lt65\longrightarrow$ divide both sides by -5; reverse the inequality sign $-5h\div-5\gt65\div-5\longrightarrow$ divide $h\gt -13$ Check the inequality. $-5(3)\overset?\lt65$ $-15\lt65\checkmark$ Since -13 is not included in the solution, the endpoint of the graph is an open circle.
