Step-by-step explanation:
Answer:
y = ⅕x; -5
Step-by-step explanation:
y = kx
k = y/x Divided both sides by x
k = 2/10
k = ⅕
y = ⅕x
The equation of variation is y = ⅕x.
If x = -25,
y = ⅕(-25) = -5
Answer:
2a + 2b + ay + by
Step-by-step explanation:
(a+b)(2+y)
What you do first is distribute it out.
When you do that you get a x 2, a x y, b x 2, and b x y
2a + 2b + ay + by
That is as simplified as it is going to get because you have no more common factors.
Hope this helps!!!
