Jason is participating in a walkathon. He writes the equation m=2d+50 to represents the amount of money m(money) he collects from each sponsor for walking d (distance) kilometers. What member represents the rate of change?

What is the test that you can do to tell if a graph represents a function?

A

the horizontal line test

B

the vertical line test

C

the expression test

D

the litmus test

Step-by-step explanation:

d

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
