Answer:

D. -23

Explanation:

The question wants you to plug in the -7 into the equation. So in this case it wants you to plug the -7 in so it looks like this:

-2(-7)-9

Now it's just simplify which would be easy. Follow PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction). Do the multiplication first so you get -14-9 and then you'll get -23.
