You would take the number of ice cream cups which is 12 and divide it by the cost which is 9.60
12/9.60=1.25
10................................
Answer:
what grade is this?
Step-by-step explanation:
We know that f(x) = 7x + 8. So, take the derivative of this function with respect to x.
This gives
f'(x) = 7
Now, you probably realized that the x value disappeared. This means that no matter what value of x you use, the derivative of this function is always going to be 7, even at x = 5. That is, the rate of change of this function is always going to be a rate of 7.
