In a bike race, Jeremy maintains a speed of one mile every five minutes for the first 30 minutes. This situation is represented by the following set of ordered pairs: (5, 1), (10, 2) (15, 3), (20, 4), (25, 5), (30, 6). What equation represents this relationship?

Step-by-step explanation:

The first one (5,1)

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)

(23*2)-12=x     x=34
