Question

If 2 > -a, then _____. a > 2 a > -2 a < 2 a < -2

Answer 1

a > -2

Explanation:

The rule is, that if you multiply (or divide) by a negative number, you must reverse the inequality symbol.

Also, if you ever need to rearrange your inequality, like switch the left and right sides, make sure to keep the symbol pointing at the same number to make sure you have written an equivalent statement.

2 > -a

Multiply (or divide) both sides by -1. Don't forget to reverse the symbol.

-2 < a

The "wide side" is towards the a and the point is towards the -2. Rearrange, but keep that the same.

a > -2
