For the inequality x≤−3 , which number(s) listed makes the inequality true? (Check ALL that apply!)

To make the inequality true for x ≤ -3, we need to select any number that is less than or equal to -3.

The numbers that satisfy this inequality are:
-4
-5
-6
-100

Thus, all of these numbers: -4, -5, -6, and -100 make the inequality x ≤ -3 true.
