OpenStudy (buttermequeasy):

|x + 2| + 16 = 14 x = −32 and x = −4 x = −4 and x = 0 x = 0 and x = 28 No solution

OpenStudy (amistre64):

you cant negate an absolute value

OpenStudy (buttermequeasy):

I know.

myininaya (myininaya):

\[|something| \neq negative something \]

OpenStudy (amistre64):

| | = -# not good

OpenStudy (amistre64):

sites still going slow

myininaya (myininaya):

so what happens when you subtract 16 on both sides don't we have |junk|=negative something?

OpenStudy (buttermequeasy):

???

OpenStudy (anonymous):

|x+2| +16=14 -16 -16 |x+2|=-2 x+2=-2 -2 -2 x=-4 I don't know how you got the second part but that's how i would do the first part

myininaya (myininaya):

|x+2|=-2 never happens for any input

myininaya (myininaya):

|something| is either positive or neutral

myininaya (myininaya):

|something| is never negative

OpenStudy (anonymous):

What do you mean? you just drop you absolute value and subtract 2 on both sides to cancel out the 2 on the side with the variable. and only |inside| has to positive..everything outside the | | can be whatever

myininaya (myininaya):

we can put anything into | | and the output will either be 0 or positive

myininaya (myininaya):

| | represents distance

myininaya (myininaya):

distance is either positive or zero

myininaya (myininaya):

distance is never negative

OpenStudy (anonymous):

| | is called absolute value.. look it up on google.. Are you talking about highschool algebra or college?

myininaya (myininaya):

absolute value is the distance of some number to 0

myininaya (myininaya):

|-3|=3 |0|=0 |3|=3 |-141441|=141441 look the outputs are never negative

OpenStudy (buttermequeasy):

So the answer is no solution ?

OpenStudy (anonymous):

That's what i'm saying.. I didn't put a negative inside the bars i put them on the outside

myininaya (myininaya):

butter ask yourself can you ever get a negative output for |something| the answer is no

myininaya (myininaya):

|junk| is never negative

myininaya (myininaya):

\[|junk| \neq negative something \]

OpenStudy (anonymous):

I know that... i didn't make |junk| negative it was still positive

OpenStudy (buttermequeasy):

I know that an absolute value can never be negative!

myininaya (myininaya):

then what you know there is no solution

myininaya (myininaya):

to this equation you have

OpenStudy (buttermequeasy):

Okay, thank you. Just making sure.

myininaya (myininaya):

\[|x+2| \neq -2 \]

OpenStudy (anonymous):

see there is no negative except on the OTHERSIDE of the = sign.. and you can do that..

myininaya (myininaya):

no you cannot |junk| is never negative

myininaya (myininaya):

|x+2|=-2 has no solution
