Answer:

see explanation

Step-by-step explanation:

to evaluate f(g(x)) substitute x = g(x) into f(x), that is

f(g(x)) = f(x - 1) = 3(x - 1) = 3x - 3

Similarly to evaluate g(f(x)) substitute x = f(x) into g(x)

g(f(x)) = g(3x) = 3x - 1

Oksanka [162]

24% of the cars were travelling above the speed limit.

Step-by-step explanation:

Given,

Total cars monitored = 25

Cars traveling above the speed limit = 6

Percent of cars traveling above speed limit = \frac{Cars\ travelling\ above\ speed\ limit}{Total\ cars\ monitored}*100

Percent of cars = \frac{6}{25}*100\\

Percent\ of\ cars=\frac{600}{25}\\Percent\ of\ cars=24\%

24% of the cars were travelling above the speed limit.
