The work is down there... the answer is X= 0.93 0r X=1.07
Answer:
Step-by-step explanation:
g(h(-3)) = g(7)
As h(x)= 4-x so h(-3) = 4+3=7
(g•h)(-3)= g(7) = 7+1/7-2= 8/5
10.
a) x- is the time after which the total cost is the same.
24 + 99x - is the cost in the dealership
45 + 89x is the cost at the local mechanic
24 +99x = 45 + 89x
99x - 89x = 45 - 24
10x = 21
x= 2.1 (hours)
b) 24 +99x < 45 + 89x
x< 2.1
The repairs cost less in dealership when work takes less than 2.1, and the dealership is better, because the cost of parts is less in the dealership.
