what about -3?-/-3/
Similarly, make two equations: -3 ? -3 and -3 ? 3 Now find the signs..
-3 < or > 3? You do the math.
The first one is \[-3 = -3\]
You have to find the other now...
What sign will come in: -3 ? 3
but all im trying to find is the ? right ... which is =
Please reword it?
@rayleigh you're right -3 = -|-3|
Ramya I think there is something wrong in it...
please use "|" instead of a slash, so that the question doesnt become confusing :P
Is -3 < or > 3?
i dont know how to do that ;P
why.. negative of absolute value is negative of value itself
\(-3 = -(3)\) and \(-3 \ne = -(-3)\)
It will form two equations: \[-3 = -(3)\] and: \[-3 \ne -(-3)\]
second statement is incorrect. we can use that concept only for inequalities. not here i suppose
\[|x|\] is always taken as: x and (-x) We first break it and then solve..
will those 2 equations have different answers? theres only 1 ?
Yes they will have different answers -3 = -3 and -3 < ..3
@waterineyes missing the -ve sign outside the mods -3 = -3 and -3 = -3
negative sign outside the mods sticks. we cannot remove it
what about this one /p/=2
p = 2 (or) p = -1
* p = -2
thats what i thought
did i do this right ? /z/=0.3 z=-0.3
no any |mod| value gives two values. pls check @waterineyes method in the beginning. |z| = 0.3 => z = 0.3 (or) z = -0.3
i find it useful to think of mods as this : |z| = x+2 means, z value can be 2 units more or 2 units less than x
youve got what ive got
hmm
For the first question. right. its, =
@ramya I am not removing the sign..
You said -3 = -|-3|
im confused |z| = 0.3
Now this will have two values I show you: |-3| can have two values : -3 and -(-3) Now put these values in the equation: -3 = -(-3) and -3 = -(-(-3)) -3 = +3 (Incorrect) and -3 = -3 (Correct)..
mod of an EQUALITY can have only one value : +ve
mod of an INEQUALITY has TWO values : +ve, -ve sorry for the caps... just to highlight :P
the statement Now this will have two values I show you: |-3| can have two values : -3 and -(-3) is fundamentally incorrect i feel
I don't think so.. |-x| will always have two values : -x and -(-x)
thats different. here x is a variable
still it will have only one CONSTANT value. you can use -x, or +x on the way solving, but you will end up with ONE value
I have just let it as x.. It can be 3 -3 4 -4 5 7 etc...
okay.... what about this /z/=0.3
z = +0.3 z = -0.3
write a number to represent the situation. then write the opposite of that situation and write a number to represent it. 2 rooms to the right
