Show intervals on a number line.

52. | x | < 4

54.| x | > 0

[Eigenvalue]

52. |x|<4 means the distance from x to 0 is less than 4
x<4 and x>-4
-4<x<4

54.|x|>0 means the distance from x to 0 is greater than 0
x>0 or x<0
All real numbers

52. |x|<4 means the distance from x to 0 is less than 4
x<4 and x>-4
-4<x<4

54.|x|>0 means the distance from x to 0 is greater than 0
x>0 or x<0
All real numbers

Thank you again. Where's the number line?

I will post the picture of the number one
Closed circles for < or >
Open circles for [tex]\le[/tex] or [tex]\ge[/tex]

You are going to post a picture of the number one. Do you mean 52 or 54?

I don't see a number line here.
