MUST BE STAPLED

Algebra 1 Swine Flu Packet:
I hope you and your families are okay.

I shouldn’t have to tell you this, but I will anyway. This is not the time to try and see what you can get away with in terms of doing your work for this and all your other classes. We are missing a week of class time, through no fault of our own. This swine flu situation hit us and the school dealt with it in the best way possible to ensure the health of the student body and school community. That being said, missing a week of school this close to the end of the year is not a good thing. Take the learning packets from all your classes, whether they contain review material or new material, as an opportunity to get some of that class time back. I stress that I’m not just talking about this class. I’m talking about all your classes. Do not do just enough to get credit…. Do your best on all the learning packets and make the best out of an unfortunate situation. For our class assignment, use the answer key only if you get stuck. Remember you may be able to fool me on Monday, but the final and regents won’t lie.

In this class, we were just starting with Graphing the Parabola. I see no reason to give you a ton of parabola questions. We’ll do one a day. Use your parabola notes to help you with the calculator steps. I don’t expect perfection, but do your best. We will also use this as an opportunity to review for the quarter exam (yes, you do have a cumulative 4th quarter exam.) and the final.

DO NOT JUST GIVE UP AND SKIP PROBLEMS. Use your notes, the copies of the step by step answer keys that have been given out, or note packets from the website. Call a friend. Call an enemy. Call the police. I don’t care. Whoever you think can help you, wherever you can look for help, whatever you can think of doing, DO IT. Make sure you know how to do the problems. They are not going away. They will be part of my 4th quarter exam, the final, and the regents. Take this opportunity to make up for not doing what you should have done when 1st covering these topics.

These problems are not meant to be done in 1 day. Split up the joy over the 3 remaining days you are out of school. You’ll enjoy the problems more that way.

Print out the sheets and do the work in the space provided. If your printer doesn’t work, go to the library. It will be empty, all the other kids have school. If the graphs don’t print use your own graph paper and staple the packet and graph paper together.

For the parabolas, graph only the points that fit on your graph.
When it says: Graph: y = - x2 – 2x + 3, for -4 x 2 that means your table will start at x = -4 and finish at x = 2.

Wednesday, April 29
1) a) Graph: y = x2 - 2x – 8, for -3 x 5
b) Is the vertex a minimum or maximum?
c) Find the axis of symmetry.
d) Find the vertex.
e) Find the roots.

2) Solve the system algebraically and check: (Kriss Kross makes you jump, jump!)

11x – 4y = 113
3x + 8y = -1

3) Factor: No T! (Go back to factoring packet if you need steps for Case II, part d)
a) 3x2 - 3x – 168b) 8x3 + 24x2 + 16xc) 5x9 – 320x7d) 6x2 - 7x – 5

4) Met jerseys cost $85 and Yankee Jerseys cost $93. If 200 jerseys were sold and total sales were $18,592. How many of each were sold? True story…. (Remember special let, x; 200-x)

5) Solve:
a) x2 – 7x = 44b) 9(6x + 4) = 8(5x - 6)c) 2(9x - 4) - 8(4x - 7) = 181

Wednesday Answer Key:
1) a) min. b) x = 1 c) (1,-9) d) (-2,0)(4,0)2) (9,-3.5)
3) a) 3(x- 8)(x+7) b) 8x(x+2)(x+1)c) 5x7 (x – 8)(x+8) d) (3x-5)(2x+1)
4) 199 Yankee jersey, 1 mets jersey (true story) 5) a) x = {-4,11} b) -6 c) -9.5

Thursday, April 30
1) a) Graph: y = - x2 – 2x + 3, for -4 x 2
b) Is the vertex a minimum or maximum?
c) Find the axis of symmetry.
d) Find the vertex.
e) Find the roots.

2) A jar of change has $74.15 in it. There are 7 nickels less than twice the amount of dimes and 6 less quarters than triple the amount of dimes. How many nickels, dimes, and quarters are in the jar? (There are no pennies.)

3) Graph the system of inequalities – Remember to test and shade (Go back to graphing packet if you have to.)
x 4
-3x – 12y > -24

4) Factor: No T! (Go back to factoring packet if you need steps for Case II, parts and b)
a) 36x2- 15x - 9b) 36x2 + 13x + 1c) 169x2 – 4d) 36x2 – 16

Thursday Answer Key:
1) a) max. b) x = -1 c) (-1,4) d) (-3,0)(1,0)2) 153n, 80d, 234q3) graph
4) a) 3(4x-3)(3x+1) b) (9x+1)(4x+1)c) (13x+2)(13x-2) d) 4(3x+2)(3x-2)

Friday, May 1
1) a) Graph: y = x2 + 6x + 5, for -6 x 0
b) Is the vertex a minimum or maximum?
c) Find the axis of symmetry.
d) Find the vertex.
e) Find the roots.

2) At Barnes and Noble Bookstore a book called Yankees: The Championship Years is sold for $30. They also sell a book called Mets: The Championship Years for $5 (as it is a MUCH shorter book). If the store sold 150 books and total sales were $4,450, how many of each book were sold? (Special let from Wednesday… )

3) Graph the system of equations and check – Remember to check the point of intersection in both original eq.)
y + 2 = - ⅔(x – 12)
18x – 12y = 84

4) Solve: T it Up!
a) x2= 16x - 63b) x3- 132x = x2c) 5x2 – 11x + 9 = 6x2 – 7x + 9
