Answer:

0 and -18

Step-by-step explanation:

The absolute value (|  |) of any number is a positive. Example: | -2 | = 2 and

| 2 | = 2.

But first you solve what's on the inside. If you have it as | 9+0 |, then you get | 9 | which equals 9. If you have -18, you have | 9+-18 | or | 9-18| and that gives you | 9 | which equals 9.

The absolute value is basically how far your number inside the | | is from 0. It will never be negative.

I hope this helped :)

The answer is C. You can prove that my answer is right by substituting 0 and -18 for x. Remember if -18 is put inside absolute value bars then it becomes 18. But if 9 is placed in the absolute value bars then the answer is 9 not -9.
