OpenStudy (notamathgenius):

Do you know what this is ? \[\left| x \right|\]

OpenStudy (anonymous):

Nah.

OpenStudy (notamathgenius):

It means Absolute value, meaning anything in between those lines makes it automatically positive

OpenStudy (anonymous):

mk, so b and d are wrong then.

OpenStudy (notamathgenius):

Exactly now just take the numbers and plug it in x with x and y with y

OpenStudy (anonymous):

im not even sure.

OpenStudy (notamathgenius):

|-x - 2y| x = -5 and y = 5. you take -5 and put it with -x and it makes it 5 and you put 2y and make y 5

OpenStudy (anonymous):

so c?

OpenStudy (anonymous):

A..?

OpenStudy (notamathgenius):

It's a -5 is in between absolute value so its 5

OpenStudy (anonymous):

You can only take it out unless it is a positive not a negative . lol somewhat like jail
