Karla's starting salary was $32,200. she gets a $700 raise every year. write an equation that models this.

Karla's starting salary was $32,200. She gets a $700 raise every year.

Constant increase in salary is $700. so 700 is the rate of increase or slope.

Let x be the number of years and y be the salary .

There is a constant increase in salary every year so we use equation

y= mx + b

Where m is the slope and b is the y intercept

y intercept is the initial salary that is 32,000

m is the rate of increase that is 700

Replace the values of m and b

y = 700x + 32000

The required equation is y= 700x + 32000.

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)
