Can someone explain to me how to graph the equation in the top left corner? i know that line is right but i don’t know why.

This is just y=mx+b in simplified terms.

The traditional way would be written as:

Since the slope and the y-intercept both have the same denominator, you can put it under (x-5)

Since there is an understood 1 in front of x, it is still treated as .

Since the y-intercept is positive , you can change them both to negative and it will be positive.

I know this explanation is confusing, but it is rarely seen like this. Just understand that it is equivalent.

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)

hope this : )
