Answer:
B) x ≥ -9
Step-by-step explanation:
The division property of inequality states that when we divide both sides of an inequality by a negative number, the direction of the inequality is reversed.
Therefore, to solve -2x ≤ 18, we divide both sides of the inequality by -2 and reverse the direction of inequality sign:
[tex]\sf -2x \leq 18 \\\\\\\dfrac{-2x}{-2}\leq \dfrac{18}{-2}\\\\\\x\geq -9[/tex]
So, the missing step in solving the inequality is:
[tex]\Large\boxed{\sf x\geq -9}[/tex]
