Answer:
6x +12
Step-by-step explanation:
Falling at the rate of 2.5 m/s for 45 seconds, the anchor fell
(2.5 m/s) x (45 s) = 112.5 meters .
If it wound up only 40 meters underwater, then it must have fallen
(112.5 m - 40 m) = 72.5 meters
from its storage position on the big cruise ship,
before it ever reached the water.
Since it was falling at the rate of 2.5 m/s, it took
(72.5 m) / (2.5 m/s) = 29 seconds
to get down to the water surface after it started dropping.
1/12th of 60 is 5 (5 x 12 = 60)
f(X)=3/x-1,g(x)=2/x
g.f(-5)=g(f(-5))=g(-3/5-1)=g(-3-5/5)=g(-8/5)=2×(-5/8)=-5/4
