f = (f1 f2) / (f1 + f2)
f(f1 + f2) = f1 f2
f f 1 + f f 2 = f1 f 2
f1 f2 - f f2 = f f1
f2 (f1 - f) = f f1
f2 = (f f1) / (f1 - f) <==== solution
Answer:
The Domain is {3,2-1,0} Range {7,4,2}
Step-by-step explanation:
It is a function because there is one value of y for every x value.
The jogger moves 5.4 mph / 60 = 0.09 miles per minute.
