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

$–4 ≤ 9$

$x < 1$
Hint (b):
What if $x$ is $7$ ?
What if $x$ is $−4$ ?

$–5 > -2$

$3x + 5 = 2$
Hint (d):
$3x + 5 = 2$
$−5 \quad \ \ \ −5$

$3x = −3$
If x is equal to $−1$ , then the statement is true.
Any other time the statement is false.
