Answer:

sometimes

Step-by-step explanation:

|x| =x

We can look at 3 case, when x>0, x=0, and when x<0

If x>0

|3| =3

3 = 3

True

x=0

|0| =0

0 = 0

True

x<0

|-3| =-3

3 = -3

False

Hello from MrBillDoesMath!

Answer:

Sometimes!

Discussion:

Consider these examples:


abs(3) = 3                           ( so abs(x) = x for this value of x)

abs(-3) = 3                          ( so abs(x) <> x for this value of x)


In general,

if x >= 0, then abs(x) = x

if x < 0, then abs(x) = -x



Thank you,

MrB
