QUESTION 9 of 10: Suppose cash income for the first three months is $200, 5850, and $1,060. Total expenses for these same three months are $4,200, $2,800, and $1,900. Which is the cumulative amount of cash available at the end of each month? Assume So starting cash.
a) $6,000-$5,750,-$4,380
b) $4,000,-$5,950,-$6,790
c) $4,000,-$2,850, $5,170
d) $5.000,-$7.260,-$8,160

c) $4,000,-$2,850, $5,170

Step-by-step explanation:

were is the equation

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.
