After all of the start-up costs, a company starts has $100 and makes $0.75 on each unit sold. write a linear equation in slope-intercept form that models this situation using p for profit and n for number of units sold.
a) p = 100n + 75
b) n = 100p + 75
c) p = 0.75n + 100
d) n = 0.75p + 100

The linear equation that in slope-intercept form is p = 0.75n + 100.

Given that,

Based on the above information, the linear equation should be

p = 0.75n + 100

Therefore we can conclude that the linear equation that in slope-intercept form is p = 0.75n + 100.

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.
