Answer:
+13
Step-by-step explanation:
-4-9 gives -13
when +13 is added to -13 , the expression becomes +13+(-13) =13-13=0
these are my two answers
5+8=13. | 8+5=13.
It's A
y=-1/5x-16/15
slope intercept form y=mx+b
3x+15y=-16
15y=-3x-16 divide both sides by 15
y=-3/15x-16/15 simplify -3/15 to -1/5
B. 18x3 + 6x2 + 14x - 72
