Answer: x = 17 
Step-by-step explanation:
From the question: y α x
⇒ y = kx
y=4 and x = 10 implies
4 = 10k
k = 4/10
k = 2/5
substitute k = 2/5 into the equation
y = 2/5 x
When y = 7 , the equation becomes
7 = 
35 = 2x
35/2 =x
Therefore : 17 
x =
Answer:
7x2 + 3y2 - 4x
Step-by-step explanation:
Answer:
8x + 8
Step-by-step explanation:
There are 8x and the numbers equal 8.
If you go from x + 6, the numbers add up to 8
Using distribution it would be 3m+7
The answer to that question is If h(x) = 7 + 6f(x) , where f(4) = 7 and f '(4) = 3, find h'(4).
