Which inequality is equivalent to -m ≥ 15?
Vera_Pavlovna [14]

Answer:

m ≤ -15

Step-by-step explanation:

You can convert m into positive by multiplying -1 on both sides of the equation. This would also result to a -15.

Note that when an unknown variable changes its sign, the symbol becomes the opposite version of itself.

So,

-m ≥ 15

-m(-1) ≥ 15(-1)

m ≤ -15
