Do u know how to add negatives?

OpenStudy (ilovecake):

no

To solve this, we need to substitute the x and y given, so -4 and -12, which would give us -4 + |-12|. The question is asking for the absolute value (Because of the | | marks) of -12. Do you understand what absolute values are?

OpenStudy (ilovecake):

-8

OpenStudy (anonymous):

You're close, but you're thinking of -12 + 4. Instead, think -4 + 12, because the absolute value of |-12| is 12.

OpenStudy (ilovecake):

16

OpenStudy (anonymous):

No, still. What is 12 - 4?

OpenStudy (ilovecake):

8

OpenStudy (ilovecake):

it is c

OpenStudy (anonymous):

Yes! So your answer would be C. I got this because x + |y| is -4 + |-12| with the given values, and the absolute value of -12 is 12. So, the equation is just -4 + 12 = 8.
