As they are written, they are all linear. I think you meant for the third one to be y=x^2. if that is true then y=x^2 is a quadratic and therefore is the answer
Answer:
1493
Step-by-step explanation:
The two numbers are 10 and 1. When you add 10 and 1, it adds up to 11. When you multiply 10 by 1, the answer is 10.
Hope it helps :)
X+y=42, 4y+2x=114
y=42-x
4(42-x)+2x=114
168-4x+2x=114
168-2x=114
168-114=2x
54=2x
54/2=x
27=x
plug 27 into y=42-x
y=42-27
y=15
