difference between an absolute value being 24 and an absolute value being -2?

6 years ago
myininaya (myininaya):

|x|=positive is fine we get solutions |x|=negative we get no solutions

6 years ago
OpenStudy (anonymous):

one is possible, and one is not

6 years ago
myininaya (myininaya):

|x|=0 we get one solution

OpenStudy (anonymous):

is that the question?

6 years ago
myininaya (myininaya):

do you get that y=|x| will never intersect a y=negative constant?

6 years ago
OpenStudy (saifoo.khan):

But in the second one, the answers were in -ve.

myininaya (myininaya):

what is ve?

negative maybe?

6 years ago
OpenStudy (saifoo.khan):

yes, negative.

saifoo my friend if \[|\text{something}|=p\] then \[p \geq 0\] or there is no solution. the "something" could be positive or negative

|x|=-3 \ /y=|x| \ / \ / ----------------x axis --------------y=-3 never intersect |x|=3 y=|x| \ / --------------------y=3 \ / \ / \ / ---------------------------x axis two intersections

forget the doggone graph. absolute value of something is positive or zero. it is never negative. what is inside the absolute value sign could be positive or negative, that is the input. but the output is positive

myininaya (myininaya):

|x|=0 has one intersection at x=0 y=|x| \ / \ / \ / -----------------------x axis y=0

so if i write \[|\text{blah}|=-3\] for example, i can just go fish because there is no way that the absolute value of anything is negativfe

oh they are very creative and i like them, but i do not need a graph of anything to tell me that the absolute values of something is non-negative

myininaya (myininaya):

i know you don't need it

i like piecewise someone here was trying to peddle a video of themselves solving absolute value equations with the graph. i think it is way more trouble than it is worth
