Answer:

Her average speed is 48 miles per hour.

Step-by-step explanation:

1. You have to do order of operations in reverse (PEMDAS in reverse)

2. Divide 36 by 3/4 which would be to multiply by the reciprocal (multiplying 36 by 4/3)

3. The answer would then be r=48

How would i do number 2?
vekshin1

Answer:

m=2

Step-by-step explanation:

When you put a number into the inverse of a function (f^-1) you get the original number back.

Ex: f^-1(11) = (11-3)/2 = 4

f(4) = 2×4+3 = 11

So, f(-5)=-2

So, when x is -5,

f(x) = -2

f(x)=m(-5)+8

-2=m(-5) + 8

m=2
