Answer:
Step-by-step explanation:
One off fee is 120 Dirhams and weekly charge is 200 Dirhams.
<u>The equation for this relation is:</u>
- y = 200x + 120, where x- the number of weeks
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:
a
Step-by-step explanation:
F(4)=.5×4+8
simplified to F(4)=2+8,
simplified even more means F(4)=10.
6x+8 <62
-8 < -8
6x/6 54/6
Answer: x< 9
