The car's average rate  is 43.7 mph. The bicycle's average rate is 12.3 mph.

To get this solution, let the bicycle's average rate be (x) and the car's average rate be (x + 31.4) mph. 

Distance= Speed x Time
364 = (x + x + 31.4) 6.5
364 = (2x + 31.4) 6.5
364/6.5 = 2x + 31.4
56 = 2x + 31.4
56 - 31.4 = 2x
24.6 = 2x
24.6/2 = x
12.3 = x

x = 12.3 mph     
x+31.4 = 43.7 mph

If g(x)=70−3x, find -g(-x)
Vedmedyk [2.9K]

Answer:

- g(- x) = - 70 - 3x

Step-by-step explanation:

to evaluate g(- x) substitute x = - x into g(x)

g(- x) = 70 - 3(- x) = 70 + 3x, hence

- g(- x) = - (70 + 3x) = - 70 - 3x
