And 3.b?
Recall that
|x| = x if x >= 0
|x| = -x if x < 0
So,
|12| = 12
|-12| = 12
1A
|-15| = 15, so
-|-15| = -15
So, -|-15| < 15
3B
recall that you can say 4 is 2 less than 6. That means 6-2 = 4
So, #2 is
y-8 = 2
2C
|x| = x if x >= 0
|x| = -x if x < 0
So,
|12| = 12
|-12| = 12
1A
|-15| = 15, so
-|-15| = -15
So, -|-15| < 15
3B
recall that you can say 4 is 2 less than 6. That means 6-2 = 4
So, #2 is
