Answer
$8.6\leq h$
Work Step by Step
$22.3\leq13.7+h\longrightarrow$ subtract 13.7 from each side
$22.3-13.7\leq13.7+h-13.7\longrightarrow$ subtract
$8.6\leq h$
A closed dot at the endpoint indicates that 8.6 is part of the solution set.
Since the variable is greater than the endpoint, the arrow continues to the right in the direction of increasing values.
