Answer:
Marcus
Step-by-step explanation:
Marcus' Polynomial: ![3x^3-4x^2y+y^3+2](https://tex.z-dn.net/?f=3x%5E3-4x%5E2y%2By%5E3%2B2)
Ariel's Polynomial: ![y^3-4x^2y+3x^3+2](https://tex.z-dn.net/?f=y%5E3-4x%5E2y%2B3x%5E3%2B2)
Marcus' polynomial is correct because by convention, variables are usually listed in alphabetical order.
Marcus Polynomial is listed in descending order of x.

The solution to a system of equations given the graphical representation is at the point of intersection of the 2 lines, that is
solution = (4, 1) ← point of intersection

31.832142857 is what you got, look at your tenths digit. if it's greater or equal to 5, it will always round to the higher number. if its less than or equal to 4, it will be the lower number.
for example, 10.4 will be 10, as it is lower than 5
or 10.6 will be 11 cause it is higher than 5
I don't quite understand the ten strategy, or what EXACTLY you're asking. But, what you can do is when you add a one digit number plus a nine, just change the nine to a ten and subtract one. It is very easy. So, 7+10 equals 17, subtract one and you get 16 which is 7+9. It is always one less than anything plus 10.
