Answer:

Activity 3: Let's Determine!

Determine if the x = -3 is a solution of the following linear inequalities.

1. x - 7 < -9

(-3)-7 < -9

-10 < -9

true

-> x= -3 is a solution

2. 4x + 5 ≤ -10

4(-3)+5 ≤ -10

-12+5 ≤ -10

-7 ≤ -10

false

-> x= -3 is not a solution

3. 5 - 6x ≥ x + 26

5 - 6(-3) ≥ (-3) + 26

5 + 18 ≥ 23

23≥23

true

-> x= -3 is a solution
