Answer 1

Sorry, C

Answer 2

Could you explain how you got the answer?

Answer 3

-2,3+(-(-5,9))=5,9-2,3=3,6

Answer 4

All you have to do to figure this out is substitute the values in. Since x is -2.3 and y is -5.9, you'll put -2.3 in wherever you see an x and -5.9 wherever you see a y. What will your equation look like once you've done that? @Vianne

Answer 5

-2.3 + (-5.9)?

Answer 6

Answer 7

Oh xD

Answer 8

Answer 9

c=-5,9;
-c=5,9;
You can write:
-2,3+5,9 or 5,9-2,3
