x (.60) + 60 (.15) = (x+60) .50
distribute
.60x +9 = .5x +30
subtract .5x from each side
.1x +9 = 30
subtract 9 from each side
.1x = 21
divide by .1
x = 210

Answer:
f(-2) = -1
Step-by-step explanation:
Look at x = -2 and find the value of y.
We will use the equation:
r t = 3/4 r ( t+12 ) /:r
t = 3/4 t + 9
t - 3/4 t = 9
1/4 t = 9
t = 9 * 4 = 36 minutes ( takes a trip to the market )
36 + 12 = 48 minutes
The ride home takes 48 minutes.
