T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
Answer:
C
Step-by-step explanation:
If the parent function is function 
and 
then
- the graph of the function
is translated a units to the right graph of the parent function; - the graph of the function
is translated a units to the left graph of the parent function; - the graph of the function
is translated a units up graph of the parent function; - the graph of the function
is translated a units down graph of the parent function.
In your case, the grapgh of the function 
is translated 2 units up the graph of the function

In order to figure out what N is you have to isolate it by dividing by 50 on both sides as shown below:
