People Missing Binders
Today – Review Session
• At 2:45 in this room
• I have a meeting from 2:30 till 2:45
Today
Objective: I CAN graph compound inequalities
Raise Your Hand if…
You are wearing a white tee shirt
ANDYou are wearing Black pants
Raise Your Hand if…
You are a female
ANDHave a binder for this class
Raise Your Hand if…
You are a male
ANDWearing sneakers
Raise Your Hand if…
You take the 79th street bus to school
ANDThe Pulaski bus to school
Let’s Define AND
AND: the word AND indicates that both statements must be true
We call this the INTERSECTION
Raise Your Hand if…

ORYou are wearing Black pants
Raise Your Hand if…
You are a female
ORHave a binder for this class
Raise Your Hand if…

You take the 79th street bus to school
ORThe Pulaski bus to school
Define OR
OR: the word OR indicates that one statement, the other statement or both statements must be true
We call this the Union
Let’s look at some math
PICK ANY number for X and write it very large on a blank piece of paper
Now hold up your number if it is true?
AND
4x
20x
Now hold up your number if it is true?
AND
30x
5x
Now hold up your number if it is true?
OR
100X
50x
Now hold up your number if it is true?
OR
100X
50x
Now hold up your number if it is true?
OR
7X
3x
Now let’s Graph
Example #1 – Graph7x 2xAND
0 1 2 3 4 5 6 7 8
72 xWe can write this as:
Example #2 – Part B1x 4xor
0 1 2 3 4 5 6 7 8
Try these five on your own5x3x AND
0x4x AND
10x3x OR
12x4x OR
2x5x AND
Example #3: Write the inequality
-5 -1 0 1 2 3-2-3-4
1x 3xor
Example #4
-5 -1 0 1 2 3-2-3-4
5x 1xand
