Question

|x| = -x if x<0....[true or false] give reasons as well​ ....please tell

Answer 1

Answer:

true

Step-by-step explanation:

modulus of x will give you the numerical value of x, irrespective of the sign. since the output will be positive, it would be -(x), as x is already negative

for example, let's take a value for x that satisfies x<0:

x = -2

|x| = |-2|

= 2

since x= -2, it is clear that here |x|= -x, as -x = -(-2) = 2

Answer 2

Answer:

false.

Step-by-step explanation:

because in modulus if negative sign it will be positive when we come out from modulus it will be positive ....
