Answer:
y=2/-1 -3
Step-by-step explanation:
Place values:
As each is in a different place value, when we add them neither will affect the other, meaning:

Answer: B 4.39
Answer:
x = 18
Step-by-step explanation:
the sum of any exterior angle is equal to the sum of any two interior angles
3x-11 + 5x+14 = 9x-15
8x + 3 = 9x - 15
3 = x - 15
x = 18
Simplifying-
(6d^2)(-7d)=
= -(42d^2)(d)
=-42d^3

So y=2x is the only answer that fit y=kx, while k=2
