The answer to this question is 100% B: y=2x+7 I hope this helped you! :)
d = Diameter of wheels = 25 inches
s = Distance to be traveled by the wheels = 458 miles
Converting the miles to inches
The distance traveled by the wheels in rotation is the circumference
The number of rotations required to cover the distance would be
rotation is 
so
The number of rotations to cover the required distance is

no, y does not relate to x. x is going down by .5 and y is going down by a third of the original number.
Step-by-step explanation:
23. area of rect,r = 11 x 3.5 = 38.5cmsq
area of tri, t = 6 x3.5/2 = 10.5 cmsq
area of shaded region, sr = r-t
=> sr = 38.5- 10.5 = 28.5cmsq
24. area of square, s = 10x10 = 100mmsq
area of circle, c = pi x 5^2 = 78.5mmsq
area of shaded region, sr = s - c
=> sr = 100- 78.5 = 22.5mmsq
25. area of circle, c = pi x 6^2 = 113.04insq
area of tri, t = 6x12/2 = 36insq
area of shaded region, sr = c - t
=> sr = 113.04 - 36 = 77.04insq
