Answer:
w=14
Step-by-step explanation:
29-15=14
F(x)=(4x-3)^-1(10))
(-4x+3(10))
(-4x(30))
i think that's how you would solve it i can't quite remember if you substitute the x with the 10 but if you do it would be
f(x)=4(10)-3
40-3
37
but im pretty sure it's the first way.
To find the constant variation, solve for only one hour (in this case).
Divide 100 with 2
100/2 = 50/1
Each hour is 50 miles driven, so your constant variation is 50 mph
50% is exactly half, so to find half of something you just divide it by 2= 7.5
Or you could multiply it
15 x 0.50=7.5
