is x=|-x| aLWAY SOMETIMES OR NEVER
1=|-1| always sometimes or never?
always
how can you tlel
tell*
remember, when something is just an x, imagine a 1 in front of it
so is 1=|-1| always true?
that what i am asking
It is. The absolute value of -1 is in fact one. 1 is 1 away from zero, and "−1" is also 1 away from zero. So the absolute value of 1 is 1, and the absolute value of −1 is also 1
ok see this sign I I means that every number whatever that may be negative or positive when you remove this sign that will ultimately become positive.
think of it on a number line, i have one that shows an example with the number 6, it is 6 away from 0 on each side. notice that it is a positive 6 away, thus the absolute value of a negative is a positive version of itelf
in simple words the basic property of this sign which is called module is that it makes every number positive when you remove the sign then x=x which is equality.
