Answer:
x= -5 y= -1
Step-by-step explanation:
7/10 because you add seven and three which equals ten, and seven of them are dimes.
15x+5y+6
It can be simplified further if there is an amount this is equal to.
Answer:
15
Step-by-step explanation:
Rate of change is the slope of the tangent which will be the derivative of the function
if f(x) = 3x² - 4
f'(x) = 6x
as the derivative is linear, the average rate of change will occur at the midpoint of the interval
f'(2.5) = 6(2.5) = 15
