we have the inequality
[tex]\frac{h}{-24}\leq18[/tex]Solve for h
[tex]-\frac{h}{24}\leqslant18[/tex]Multiply both sides by 24
[tex]\begin{gathered} -\frac{h}{24}*24\leqslant18*24 \\ -h\leq432 \end{gathered}[/tex]Multiply both sides by -1 (Note that the sign of inequality changes too)
[tex]h\ge-432[/tex]therefore
The answer is
