Answer:
g(f(x)) = 8x-18
Step-by-step explanation:
Given that,
f(x) = 5 - 2x
g(x) = -4x + 2
We need to find g(f(x))
.
g(f(x)) = g(5-2x)
= -4(5-2x)+2
= (-4) (5) +(-4)(-2x) +2
= -20 +8x +2
= 8x-18
Hence, the value of g(f(x)) is 8x-18

The arrival time in london of a train that leaves Leicester to london at 11:50 A.M is 13:05 pm.
To calculate the arrival time in london of a train that leaves Leicester to london at 11:50 A.M, use use the formula below.
Formula:
- Ta = [(d/s)+11:50]....... Equation 1
Where:
- Ta = Arrival time
- d = distance from Leicester to London
- s = Speed
From the question,
Given:
Substitute these values into equation 1
- Ta = [(100/80)+11:50]
- Ta = 1.25h+11:50
- Ta = 1 hours 15 minutes +11:50
- Ta = 13:05 pm
Hence, the arrival time in london of a train that leaves Leicester to london at 11:50 A.M is 13:05 pm.
