Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle.
A (-5, 2), B(-5,-4),C (5,-4), D(5,2) What is the Area?
A = bh
A = 10 x 6
A = 60 square units

Which inequality matches the graph?
x>=2
When we switch the x and 2, we also have to flip the inequality symbol

Mr. Thompson’s class was competing in field day. There were 16 boys and 12 girls in his class. He divided the class into the greatest number of teams possible with the same number of boys and girls on each team. How many teams were made if each person was on a team? How many girls were on each team? How many boys were on each team?
You are trying to find the GREATEST number of teams with the GREATEST number of girls and GREATEST number of boys on each team.
GCF = 3 x 2 x 1
GCF = 6 Teams with 4 boys and 3 girls on each team

Using the number line, determine if each expression is true or false.
1. FALSE a is further LEFT so it is LESS than b (a < b)
2. TRUE the absolute value of 0 is 0 because 0 is not positive or negative.
3. FALSE .... The absolute value of 0 is 0 and the absolute value of b is still positive. 0 < all positive numbers

Camryn practices the trumpet every 11th day and the flute every 3rd day.
How many days until Camryn practices the trumpet and flute on the same day?
You need to find the LCM (Least Common Multiple)
3 and 11 are both prime numbers.
The first time Camryn would practice BOTH would be the 33rd day.

Which inequality matches the graph?
x ≤ -1 x > -1
-1 > x -1< x
x < -1 but that isn't a choice so...
reverse the -1 and x but you also must reverse the symbol:
-1 > x
****The circle is OPEN so you do NOT include the equal sign

What can we say about D?
- D is OPPOSITE of E
- D = B
- E = C
- D means the OPPOSITE of D
D is 1 so the opposite of D is -1 so ...
- D = B

The Crossroads Middle School band needs to raise more than $1500 for new instruments. If they sell wrapping paper for $8 per roll, how many rolls will they need to sell?
8x < 1500 8x >1500
8x ≤ 1500 8x ≥ 1500
MORE THAN means that it can be more but not equal
8x > 1500

The city of New Orleans is 2 meters below sea level.
- What is sea level?
- What is the elevation of New Orleans?
- What is the distance from sea level?
1. Sea level is 0.
2. New Orleans elevation is -2 or 2 m below sea level.
3. New Orleans is 2 meters from sea level (distance can't be negative)

The temperature is -16.4﮲C in Alaska and - 5.8 ﮲C in Minnesota.
Which is the correct symbol for each inequality?
1) -16.4 ____ -5.8
2) -5.8 ____ -16.4
1) -16.4 < -5.8 because -16.4 is further LEFT
2) -5.8 > -16.4 because -5.8 is further RIGHT
***The further LEFT you go on a number line the LOWER or LESS the number's value.
****The further RIGHT you go on a number line, the GREATER the number's value.

Which inequality is TRUE?
- 6 3/8 is further LEFT on the number line so it is LESS THAN - 4 1/9

The recommended maximum speed for the German Autobahn expressway is 130 km per hour.
Write an inequality for this.
K ____ 130
K ≤ 130
MAXIMUM means you can go all the way up to that number but you can NOT go over it

A theme park uses positive numbers to represent when a roller coaster is above ground and negative numbers to represent when a roller coaster is below ground.
How would the theme park represent a roller coaster that is 5 meters below ground?
Below ground would be negative numbers so...
-5 meters

Which quadrant would
(2.5, -2) be in on a coordinate plane?
Quadrant IV
The first number (x) tells whether you go RIGHT or LEFT.
The second number (y) tells you whether to go UP or DOWN.
(2.5, -2)
The first number is POSITIVE, so you go RIGHT 2.5
The second number is NEGATIVE, so you go DOWN -2
