D(t) = -4t^3 + 40t^2 + 500t = 4088
4t^3 - 40t^2 - 500t + 4088 = 0
t = 7
Therefore, the plane has flown 4088 km 7 hours after it took off.
Answer:
y = -5x + 8
Step-by-step explanation:

Since the question gives you these values, all you need to do is plug it in. (x and y remain the same).
y = -5x + 8
