I agree with what that person told you. The expression -2(x+10) is equivalent to -2x-20
Multiply the outer -2 with the inner x to get -2 times x = -2x
Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20
So overall, -2(x+10) = -2x-20
--------------------------------------------
So that's how we're able to go from this [tex]-2(x+10) \ge 75[/tex] to this [tex]-2x-20 \ge 75[/tex]
The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.

Answer:True
Step-by-step explanation:
Yes, you don't have to reverse the inequality symbol since the variables are not from the other side (right).
