Answer:

r = $\frac{120t}{120-t}$

Step-by-step explanation:

Multiply both sides by r + 120.

t (r + 120) = 120r

Expand.

tr + 120t = 120r

Subtract tr from both sides.

120t = 120r - tr

Factor out the common term r.

120t = r (120-t)

Divide both sides by 120 - t.

$\frac{120t}{120-t}$ = r

Finally, switch r to the left side and you get your answer.

Answer:

b is not a function

Step-by-step explanation:

To be a function there must be a one to one correspondence.

Each x must only go to one y

b has an x that goes to two different y's

1 goes to 5 and 13. That makes it a relation not a function
