A) the Johnson family will travel 300 miles in 5 hours
Assuming 5, represents the amount of hours & 300 representing miles
The first one is 4
The second one is 2.449489743 or 2.45
8x-5 would be the largest angle because as you approach a larger and larger x value, 8x-5 will skyrocket past the other two. Also when you plug in a low value like 1, 8x-5=3, which is still higher than the other two. The only exception is if you plug in a negative x value which is impossible.
8x-5

c>=3 and n<0 and p<=(9-3 c)/n
