<u>Equation of a Polynomial</u>
Given the roots x1, x2, and x3 of a cubic polynomial, the equation can be written as:

Where a is the leading coefficient.
We know the three roots of the polynomial -6, -3, and 1, thus:

Since the y-intercept of the polynomial is y=90 when x=0:
90=a(0+6)(0+3)(0-1)
90=a(6)(3)(-1)=-18a
Thus
a = 90/(-18) = -5
The polynomial is:

We must write it in standard form, so we have to multiply all of the factors as follows:





Answer:
-12

Step-by-step explanation:
its just the numbers in front of the variables
Answer:
Step-by-step explanation: Use the two points that are given to you and substitute them into the slope formula to find the answer.
m=<u><em>y2-y1/x2-x1</em></u>
m=9-5/3-1
m=4/2
Simplify the answer.
m=4/2
m=2/1
Final answer is 2.
The slope is positive meaning it is ascending (going up).

Answer:
Step-by-step explanation:
2 - 3y + 3t = -x - 2yz
I don't think you can actually solve the equation. You are not given any information about the letters (variables).
1st question
$23,760-(4000+6000)=$13,760
$13,760 x 4%=$ 550.40
2nd question
$43,300-(2000+2000)= $39,300
$39,300 x 5%= $1,965
