The $315 cost of the couch after tax, gives the cost before tax, <em>C</em>, as the following equation;
The cost of the couch with tax = $315
Let, <em>t</em>, represent the tax rate, and let <em>C</em>, represent the cost before tax, we have;
315 = C + C × t
Which gives;
Mathematically, we have the following equation;

Answer:
a) We get
So, Is the result of A+B is a polynomial:Yes
b) We get
So, Is the result of A-B is a polynomial:Yes
c) We get
So, Is the result of A.B is a polynomial:Yes
Step-by-step explanation:
We are giving the polynomial equations:
We need to find
a) A+B
So, we get
So, Is the result of A+B is a polynomial:Yes
b) A-B
So, we get
So, Is the result of A-B is a polynomial:Yes
c) A . B
So, we get
So, Is the result of A.B is a polynomial:Yes
The graph on #6 describes a scatterplot. Because years of experience is the input, this makes the starting salary our output. Finding the best fitting line in a scatterplot requires the line to follow a trajectory similar to that of the points. As a result, there will be outliers. Since I don't know what "the calculator" is meant by this problem, I have used a different program. I hope it works for you. Good luck.
