The inverse for f(x)=2x+4 is f-1(x)= x/2 -2
1679/7
=239.85...
Rounds to 240
So average rate is 240
We know that 75=5*5*3 so
5*5*3 times 5=125*3=375 then move the decimal place two places to the left (divide by 100) and get 3.75
or you could note that 0.75=3/4 so
3/4 times 5=
15/4
simplified=3 and 3/4
