9-8.

Identify the mathematical sentences below as always true, sometimes true, or never true.

1. $–4 ≤ 9$

1. $x < 1$

What if $x$ is $7$?
What if $x$ is $−4$?

1. $–5 > -2$

1. $3x + 5 = 2$

$3x + 5 = 2$
$−5 \quad \ \ \ −5$

$3x = −3$

If x is equal to $−1$, then the statement is true.
Any other time the statement is false.
Therefore, the statement is sometimes true.

Sometimes true

1. $61 = 61$

Always true

1. $–6 < –6$
