A business owner spent $4000 for a computer and software. For bookkeeping purposes, he needs to post the price of the computer a
2 answers:
Answer:
The cost of the software is $800.
Step-by-step explanation:
Here we have to solve a linear equation. In order to complete our task we need to designate the unknowns. Let us write x for the price of the software, and y for the price of the computer. By the statement of the problem we know that the price of the computer is four times the price of the software. This means that y=4x.
Also, we know that the combined price is $4000, and this stands for the addition of the price of the software and the price of the computer. The, we have obtain that
Then,
Dividing 4000 by 5 we obtain that x=800.

we know that
For a polynomial, if x=a is a zero of the function, then (x−a) is a factor of the function. The term multiplicity, refers to the number of times that its associated factor appears in the polynomial.
So
In this problem
If the cubic polynomial function has zeroes at 2, 3, and 5
then
the factors are
Part a) Can any of the roots have multiplicity?
The answer is No
If a cubic polynomial function has three different zeroes
then
the multiplicity of each factor is one
For instance, the cubic polynomial function has the zeroes
each occurring once.
Part b) How can you find a function that has these roots?
To find the cubic polynomial function multiply the factors and equate to zero
so
therefore
the answer Part b) is
the cubic polynomial function is equal to
