Using a matrix, you CAN represent adding or subtracting equations by adding or subtracting rows of numbers. Therefore the answer is True
So, the cubic polynomial function is 
No, none of the roots have multiplicity.
Step-by-step explanation:
We need to write an equation for the cubic polynomial function
whose graph has zeroes at 2, 3, and 5.
Zeros mean:
x=2, x=3 and x=5
or
x-2=0, x-3=0 and x-5=0
Multiplying all the factors:

So, the cubic polynomial function is 
No, none of the roots have multiplicity, A root has multiplicity if it appears more than 1 time. Like if (x-1)^2 is a root then 1 has multiplicity 2

First. You have to look at what kind of proportionality it is.It is an Inverse Proportion.so you see the rate of change is 2.3
Answer:
Amanda's percent of error: = .03 or 3% Dwyane's percent of error: = .02 = 2%
Looks like Amanda had the larger error.
