Select all the equations that represent lines perpendicular to y= 2x - 4. ATT 11 7-7 B. x+2y=3 c. 2x=y=3 1 7x+5 E. 3y = 6x + 5

you need to show the graph

step-by-step explanation:

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)

step-by-step explanation:

1. minimum

2. 6400

3. eight

hope this !

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
