Say Louis addresses x envelopes in some amount of time. In that time, Jane, addressing twice as many, will have addressed 2x envelopes. Total, they'll address 240 envelopes. So, we can add the x and 2x to solve for x.
x + 2x = 240
3x = 240
x = 80
If Louis addresses x envelopes and x = 80, Louis will address 80 envelopes. If Jane addresses twice as many, you do 80 * 2, getting 160 envelopes.
To fully answer this question you would have to list the plynomials or provide a picture of the question, but the answer you're looking for will have the highest exponent be 2 an example of a plynomial like this would be 94x^2 - 54y + 17x - 49
The domain is the x value.
List the x value of where all the dots are:
-6, -4, -2, 1, 4
