Question

that means x ≤ -4 is the solution set of x + 3 ≤ -
test a value not included in the solution set.
-3 ≤ -4 false
x + 3 ≤ -1
-3 + 3 ≤ -1 substitute -3 for x.
0 ≤ -1 ?

Explanation:

Step1: Check the inequality result

After substituting \(x = -3\) into \(x + 3 \leq -1\), we get \(0 \leq -1\).

Step2: Determine truth value

Since 0 is greater than -1, the inequality \(0 \leq -1\) is false.

Answer:

FALSE
