1. MES 21 9/25/13 Mrs. CabaneroAim: To be able to use the set-builder notation and/or interval notation to illustrate the elements of a set, given the elements in roster form Do Now: 1. Write in roster form.2. Write in set-builder notation.

2. Name _________ HW#11 Pd __ 9/25/13Copy all questions.p.107 #26p. 103 # 17, 30p. 93 # 3, 7p. 83 # 26, 278. Write in roster form: 9. Write in set-builder notation: 10. Write in interval notation:

3. Name ___________ HW#10 Pd __ 9/24/13p. 106 #11 Tell whether 2x – 7 = 15 is an open sentence, a true sentence, or an algebraic expression.P.106 #18 Using the domain find the solution set for 5 – n = 2p.9 # 15 True or False 17)22) Find the value of 27) 29) 40) Use > or < . The product of 6 and 7 is less than the quotient of 100 divided by 2. 48) Use < to order the numbers. -2, +8, 0, -8

4. p.106 # 25 The local grocery store has frozen orange juice on sale for \$0.99 a can but limits the number of cans that a customer may buy at the sale price to no more than five.A. The domain for this problem is the number of cans of juice that a customer may buy at the sale price. Write the domain.B. If Mrs. Dajhon does not want to spend more than \$10, the number of cans that she might buy at the sale price, y, is given by the equation . Find the solution set of this equation using the domain from part A.C. How many cans can Mrs. Dajhon buy if she does not want to spend more than \$10?

5. Methods of Describing Sets:*By roster: A roster is a list of the elements in a set, separated by commas and surrounded by braces.Example: {2, 3, 4, 5, 6} (2 to 6, inclusive)*By Set-Builder Notation: Example: (1 to 10, including 1 but not including 10)*By Interval Notation: makes use of means open, not included, greater than means open, not included, less than means closed, included, greater than or equal to means closed, included, less than or equal toExample: (1 to 5, exclusive) (1 to 5, inclusive)

6. (-2 to 4, not including -2 and including 4) (3 to 7, including 3 and not including 7)

7. EXIT Ticket: on a separate paper to be collected1.Write in interval notation.2. Write in roster form.

8. Admission to a recreation park is \$17.50. This includes all rides except for a ride called the Bronco that costs \$1.50 for each ride. Ian has \$25 to spend.a. Find the domain for this problem, the number of times a person might ride The Bronco.b. The number of times Ian might ride The Bronco, z,can be found using the open sentence Find the solution set of this open sentence using the domain from part a.c. How many times can Ian ride The Bronco?
