Monday October 29, 2018 Have the following on your desk: Glue Stick/Expo Markers Pencil Keeper Notebook: Pick up and glue into Keeper: Key Phrases

What are we learning today? How to use keys word to write inequalities.

Warm – UP WHAT ARE THE DIFFERENCES IN THE FOLLOWING VOCABULARY?? EXPRESSION EQUATION INEQUALITY

Where might I see inequalities in real life?

If it’s any smaller, you’ve got to throw him back!

What are some other situations that have more than one answer? Examples: Scores that qualify for an A: > 90 Money you need to get into Six Flags: > $39 Age required to get the kids’ meal: < 10 years old) Number of days to complete your project < 5 days

Inequalities 12-4 An inequality uses one of the following symbols. Course 2 12-4 Inequalities An inequality uses one of the following symbols. Use your white board to fill in the blanks: Symbol Meaning Word Phrases < > ≤ ≥ is less than Fewer than, below is greater than More than, above is less than or equal to At most, no more than is greater than or equal to At least, no less than

And: Symbol Meaning Word Phrases ≠ is not equal to Is not equal to

Opening You are going to Six Flags as soon as school is out (yaay!). You have to be at least 4 ft. tall to ride some of your favorite rides, but it isn’t only 4-foot tall people who can ride the rides! How tall can you be and ride the rides? See if you can figure out how to represent this with an inequality sign and a variable. (Hint: if it were an equation it would look like this: x = 4 ft. Use one of the inequality symbols from your notes to make it an inequality.) What are the possible solutions for x (the variable)? 4 ft. tall and taller x > 4 ft. 4’, 4’1”, 4’2” . . . 6’, 6’1”, etc.! And everything in between!

Write an inequality for each situation. A. There are at least 15 people in the waiting room. “At least” means greater than or equal to. number of people ≥ 15 or x ≥ 15 B. The tram attendant will allow no more than 60 people on the tram. “No more than” means less than or equal to. number of people ≤ 60 or x ≤ 60

“Use your Keeper Notes” Course 2 12-4 Inequalities “Use your Keeper Notes” Write an inequality for each situation. C. There are at most 10 gallons of gas in the tank. “At most” means less than or equal to. gallons of gas ≤ 10 or x ≤ 10 D. There are at least 10 yards of fabric left. “At least” means greater than or equal to. yards of fabric ≥ 10 or x ≥ 10

Show what you know!! Let’s practice writing an inequality #1-12 Challenge Practice: #13-15: *

Question 1: What is an Inequality? Think-Pair-Share Question 1: What is an Inequality? An inequality is a comparison of two values that may or may not be equal.

Think-Pair-Share Question 2: What is the difference between the symbols > and ≥? The symbol > means greater than. The symbol ≥ means greater than OR equal to.

Think-Pair-Share Question 3: What is the difference between the symbols < and ≤ ? The symbol < means less than. The symbol ≤ means less than OR equal to.

Think-Pair-Share Question 4: Write <, >, ≤ or ≥ to describe the number of students in each homeroom: There is a limit of 30 students for each homeroom. x ≤ 30

Math Lab Tomorrow at 8:15 HW: Unit 2 Study Guide – Due Friday

Thursday, January 8th, 2015 Warm-Up: Complete page 541 in your textbook. Under line key words in each problem and solve.

Please have a seat… Be ready for instructions! We are going a small journey today. 

Graphing Inequalities Words aren’t enough. I want to show an inequality on a number line. Can I do that?? Dr. Burger says yes! We can graph inequalities

Course 2 12-4 Inequalities You can graph the solutions of an inequality on a number line. If the variable is “greater than” or “less than” a number, then that number is indicated with an open circle. Shade left if less than. Shade right if greater than. You can graph the solutions of an inequality on a number line. If the variable is “greater than or equal to” or “less than or equal to” a number, then that number is indicated with a closed circle. Shade left if less than. Shade right if greater than.

Inequalities Flipbook Complete the third flap on your flipbook.

Inequalities 12-4 a > 5 b ≤ 3 Course 2 12-4 Inequalities This open circle shows that 5 is not a solution. a > 5 If the variable is “greater than or equal to” or “less than or equal to” a number, that number is indicated with a closed circle. This closed circle shows that 3 is a solution. b ≤ 3

Additional Example 2: Graphing Simple Inequalities Course 2 12-4 Inequalities Additional Example 2: Graphing Simple Inequalities On the back of your flipbook, graph each inequality. A. n < 3 3 is not a solution, so draw an open circle at 3. Shade the line to the left of 3. –2 –1 0 1 2 3 B. a ≥ –4 –4 is a solution, so draw a closed circle at –4. Shade the line to the right of –4. –6 –4 –2 0 2 4 6

Inequalities 12-4 Check It Out: Example 2 Course 2 12-4 Inequalities Check It Out: Example 2 On the back of your flipbook, graph each inequality. A. p ≤ 2 2 is a solution, so draw a closed circle at 2. Shade the line to the left of 2. –3 –2 –1 0 1 2 3 B. e > –2 –2 is not a solution, so draw an open circle at –2. Shade the line to the right of –2. –3 –2 –1 0 1 2 3
