Question

Solve the double inequality.
-$- 20 < - 5 \mathrm { a } \leq 0$
A) $0 \leq a < 4$
B) $0 \leq a \leq 4$
C) $0 < a < 4$
D) $- 4 < \mathrm { a } \leq 0$

Quizplus · Accepted Answer

To solve the inequality $-20 < -5a \leq 0$, divide the entire inequality by -5 (remember to flip the inequality signs when dividing by a negative number), resulting in $4 > a \geq 0$, which is equivalent to $0 \leq a < 4$.
