Well they are the same line. Because if you put x=-1 and y=1, 2(-1)+8(1)=6 and that works, now -5(-1)-20(1)=-15 and that also works so they are the same line.

-2+8=6
5-20=-15

Answer:They are the same line

Answer:

$\textsf{A)} \quad 5u^3-2u^2+5u+8$

Step-by-step explanation:

Given expression:

$(-2u^3+5u-1)+(7u^3-2u^2+9)$

Remove parentheses:

$\implies -2u^3+5u-1+7u^3-2u^2+9$

Collect like terms:

$\implies -2u^3+7u^3-2u^2+5u-1+9$

Combine like terms:

$\implies 5u^3-2u^2+5u+8$
