$\ge$
RECALL: The Multiplication Property of Inequality states that for real numbers $a$, $b$, and $c\gt0$, If $a \ge b$, then $ac \ge bc$ Thus. if $x \ge -4$, then, multiplying $3$ to each side of the inequality gives: $3(x) \ge 3(-4) \\3x \ge -12$ Therefore, the missing inequality symbol is $\ge$.
