PLEASE I NEED HELP : The total value of money (in cents) of (7x - 2 ) nickels, 4x dimes, and x quarters
Answers are either:
(75x-10) / (100x-10) / (100x-2) / or (100x+10)

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2

What is the average rate of change for this function for the interval from x=2 to x=4 ?
