2. A computer software store received two shipments of software. The cost of the first shipment, which contained 12 identical antivirus programs and 10 identical design programs,
was $1780. The second shipment, at the same prices, contained 5 copies of the antivirus
program and 8 copies of the design program. The cost of the second shipment was $1125. Find
the cost for one copy of the antivirus program and the cost for one copy of the design program.
Identify the variables, set up a system of linear equations then solve, and write a conclusion.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

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.

answer: the anser is 3
