Answer:
31.929
Step-by-step explanation:
29.95×6/100=1.797
29.95+1.797=31.929
C- Often times, if someone is using a coupon, they just want the lowest price and don't care what toothpaste is considered "the Best."
Answer:
<u>-4 </u>
Step-by-step explanation:
This is the slope-intercept form of a line equation.
This means that -5/3 is the slope of the line.
It also means that -4 is the y intercept.
<u>-4 is the y intercept.</u>
Given:
A fourth-degree polynomial function has zeros 4, -4, 4i , and -4i .
To find:
The fourth-degree polynomial function in factored form.
Solution:
The factor for of nth degree polynomial is:

Where,
are n zeros of the polynomial.
It is given that a fourth-degree polynomial function has zeros 4, -4, 4i , and -4i. So, the factor form of given polynomial is:


![[\because a^2-b^2=(a-b)(a+b)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29%5D)
On further simplification, we get

![[\because i^2=-1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20i%5E2%3D-1%5D)
Therefore, the required fourth degree polynomial is
.
To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.



_______________


___ ____

(rounded)
Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.




So, your final answer would be (3.29, 4.87).
