Answer 1

Please.

Answer 2

what abt hahd?

Answer 3

nice joke though

Answer 4

|x| is never negative is the difference

Answer 5

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

Answer 6

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

Answer 7

one is possible, and one is not

Answer 8

|x|=0 we get one solution

Answer 9

is that the question?

Answer 10

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

Answer 11

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

Answer 12

what is ve?

Answer 13

negative maybe?

Answer 14

yes, negative.

Answer 15

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

Answer 16

|x|=-3

\ /y=|x|
\ /
\ /
----------------x axis


--------------y=-3

never intersect



|x|=3

y=|x|
\ /
--------------------y=3
\ /
\ /
\ /
---------------------------x axis

two intersections

Answer 17

lol

Answer 18

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

Answer 19

|x|=0

has one intersection at x=0

y=|x|
\ /
\ /
\ /
-----------------------x axis y=0

Answer 20

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

Answer 21

no satellite i like art i won't forget it

Answer 22

art who?

Answer 23

you should like me doodles

Answer 24

my*

Answer 25

i say me sometimes like i'm irish

Answer 26

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

Answer 27

i know you don't need it

Answer 28

i don't need it

Answer 29

some people might need a visual

Answer 30

\[ |x|= \left\{\begin{array}{rcc}
x & \text{if} & x \geq 0 \\
- x& \text{if} & x < 0
\end{array}
\right.
\]

Answer 31

\[|-3|=-(-3)=3\]

Answer 32

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

Answer 33

just use the definition. halas

Answer 34

do you answer questions with him alot?

Answer 35

dunno. why do you ask?

Answer 36

i have.

Answer 37

kind of thought he/she might be a teenage girl

Answer 38

why a girl?

Answer 39
