Question

What is the solution to the inequality? m < -5 m > -5 m < -20 m > -20

Answer 1

D. m > - 20

Explanation:

`(m)/(-2) < 10`

Cancel out the negative 2, so we can leave the m alone.

`-2((m)/(-2)) < 10 (-2)`

Then, multiply the 10(-2).

Therefore, it would be...

m < -20

Now, the rule is when we divide or multiply by a negative number, the inequality sign flips. Which therefore would make the answer as:

m > - 20
