Answer 2

no you read the problem wrong it is -9

Answer 3

yes but everything inside the lines becomes positive because it is the absolute value of the numbers within

Answer 4

really?

Answer 5

thats what those straight lines mean....absolute value is making everything positive.

Answer 6

I don't think so, I beleive that the absolute value sign is removed and then you solve it as a regular equation

Answer 7

but what do I know, thats why I am on here

Answer 8

lol no because why would someone put those lines there if they are meant to be just taken away. Those lines change it all to positive.

Answer 9

the book I am going from is showing the signs to be removed and then solved

Answer 10

How would you do this?
|6x +4| + 9 17

Answer 11

the signs are removed and nothing changes if it is already positive. But if there is a (-) in it then that becomes a (+).

Answer 12

and the 9 17 what goes in between that?

Answer 13

≥
