Only answer if you’re sure :) need full equation. Will give Brainly!

Answer:

Step-by-step explanation:

Only one answer will do for this question and that is 1.

y/x = 5/5 = 1

y/x = 6/6 = 1

y/x = 1/1 = 1

The one you have to be careful with is when x = 0 y = 0. You can't solve this by using y/x because 0/0 is undefined at this point.

SOMEONE PLEASE JUST ANSWER THIS FOR BRAINLIEST!!!

Answer:

$y^2 + 8y + 16$

Step-by-step explanation:

$(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =$

The first set of parentheses is unnecessary, so it can just be removed.

$= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)$

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

$= 6y^2 + 2y + 5 - 5y^2 + 6y + 11$

Now you combine like terms.

$= 6y^2 - 5y^2 + 2y + 6y + 5 + 11$

$= y^2 + 8y + 16$
