Question

1. for the given inequality, select the possible values of $c$ when $x = 4$

$cx \leq -20$
$c \geq -5$
$c < 5$
$c > 5$
$c \leq -5$

Explanation:

Step1: Substitute $x=4$ into inequality

$C \times 4 \leq -20$

Step2: Isolate $C$ by dividing by 4

$\frac{4C}{4} \leq \frac{-20}{4}$

Step3: Simplify to find $C$ range

$C \leq -5$

Answer:

$C \leq -5$
