First, solve for either x or y. Since the first is already solved for x, solve the second for x as well;
Yea sure can u show us the problems
To solve this, we divide the price by the kilograms of peanuts.
4.5/5= 0.9
So therefore, our answer is that it costs $0.9 per can of peanuts.
hope this help you out
Answer:
f'(x) = 8x +4h
Step-by-step explanation:
For f(x) = 4x^2 +1, we have ...
f(x+h) = 4(x +h)^2 +1 = 4x^2 +8xh +4h^2 +1
Then ...
f'(x) = (f(x+h) -f(x))/h = ((4x^2 +8xh +4h^2 +1) -(4x^2 +1))/h
= (8xh +4h^2)/h
f'(x) = 8x +4h
