Answer:
f(x) = 10x - 2x + 4.
Step-by-step explanation:
This is linear because the degree of x is 1.
The others have degree 2 , degree 3 and degree -1.
(f(x) = 2/x = 2x^-1)).
Answer:
A and C are proportional relationships.
Step-by-step explanation:
Recall that a "proportional relationship" has no constant term. Thus, we eliminate Answers B and D immediately.
Answer A represents a proportional relationship: y varies directly with the square of x.
Answer C also represents a proportional relationship: y varies directly with x.

Step-by-step explanation: I hope this helps u out very much thank you :)
V = d/t
75 km/h = 480km /t
t = 480km / 75 km
t = 6.4 hours or 384 minutes
