Write the solution set using interval notation.
-$20 - 5 x \leq - 5$
A) $( - \infty , 5 )$
B) $[ 5 , \infty )$
C) $[ - 5 , \infty )$
D) $( - \infty , - 5 )$

First, solve the inequality: $20 - 5x \leq -5$. Subtract 20 from both sides to get $-5x \leq -25$. Divide both sides by -5 (remember to flip the inequality sign when dividing by a negative number), which gives $x \geq 5$. This corresponds to the interval $[5, \infty)$.
