Question

is the inequality true or false?
$4d - 10 \leq -2$
$4(1) - 10 \leq -2$ substitute 1 for $d$.
$4 - 10 \leq -2$
$-6 \leq -2$
?
true
false

Explanation:

Step1: Evaluate left-hand side

$4(1)-10 = 4-10 = -6$

Step2: Compare values

$-6 \leq -2$ is a true statement, since -6 is less than -2.

Answer:

TRUE
