Step-by-step explanation:
a) r=d/t ( same as formula of speed)
b) r= 665280/3=221760 feet/hr
c) distance in miles = 665280/5280= 126
so r=126/3 = 42 miles/hr
d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error

Answer:
f^-1(x) = (x +4)/3
Step-by-step explanation:
The inverse function is found by swapping x and y, then solving for y.
y = 3x -4 . . . . . function y = f(x)
x = 3y -4 . . . . . inverse relation
x +4 = 3y . . . . add 4
(x +4)/3 = y . . . divide by 3. This is the inverse function
f^-1(x) = (x +4)/3
The slope of function A is the coefficient of x, which is 6.
The slope of function B is the rise divided by the run, which is 3/1 = 3.
The appropriate choice is ...
... c) Slope of Function A = 2×Slope of Function B
