Answer:
[1] x - y = -10
[2] 2x + 4y = 22
Step-by-step explanation:
// Solve equation [1] for the variable x
[1] x = y - 10
// Plug this in for variable x in equation [2]
[2] 2•(y -10) + 4y = 22
[2] 6y = 42
// Solve equation [2] for the variable y
[2] 6y = 42
[2] y = 7
// By now we know this much :
x = y-10
y = 7
// Use the y value to solve for x
x = (7)-10 = -3
I am sorry if I got it wrong but I hope this helped.

Answer:
C
Step-by-step explanation:
Given
![\sqrt[4]{81y^{12} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B81y%5E%7B12%7D%20%7D)
= ![\sqrt[4]{3^{4} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B3%5E%7B4%7D%20%7D)
= 3y³ → C
It’s name would be a monomial because it only has 1 term. (Terms are departed by addition or subtraction sign) The degree would be the highest exponent in the polynomial, in this case we only have 1 term so the degree of that term is 2
