Benny gets a job at a law firm with a salary of $70,000 per year. after the first year, his salary increases to $73,000. over the next five years, he gets an increase of $3,000 every year. if you were to plot a graph of benny's annual salary, what would the slope and y-intercept bewhat equation would represent benny's annual salary over the years?

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
