Monday Updates and Algebra Answer Key for Quiz Review

Hi All!

In Green class, we worked on writing, solving, and graphing multi-step inequalities. We reviewed word problems, and practiced solving the special solutions when solving the inequalities. For homework, complete Page 80 # 1-16 all. Please look at the end of this post for the answers to your homework!

In Purple, Red, and Blue class, we learned how to identify and recognize the four different transformations that can happen to a shape. For homework, complete the Chapter 2 Fair Game Review, but remember we changed the directions on #1-6 to "Plot the points in the coordinate plane" and on the back side for #7-10, make sure you use a ruler and label each of the points A, B, C, etc.


Answer Key to Page 80 #1-16 (GREEN CLASS ONLY!):

1.) z - 6 > or equal to 11

2.) 12 < or equal to -1.5w + 4 3.) x < 0 4.) x > or equal to 8

5.) q < or equal to 6 GRAPH LOOKS LIKE: Closed circle on 6 and moving in the negative direction 6.) z <-2 GRAPH LOOKS LIKE: Open circle on -2, and then moving in the negative direction 7.) y > 1 GRAPH LOOKS LIKE: Open circle on 1, and then moving in the positive direction

8.) p > or equal to 6 GRAPH LOOKS LIKE: Closed circle on 6 and then moving in the positive direction

9.) w > -12 GRAPH LOOKS LIKE: Open circle on -12 and then moving in the positive direction

10.) x < -1/4 GRAPH LOOKS LIKE: Open circle on -1/4 and then moving in the negative direction 11.) y > or equal to 8

12.) all real numbers

13.) no solution

14.) PART A: s > or equal to 100, t > or equal to 5, u > or equal to 10. Don't forget to graph!
PART B: no; one of the requirements is to swim 100 yards, which is equal to 300 feet. If you only swim 250 feet, you do not meet this requirement.

15.) V + 100 < or equal to 700; V < or equal to 600 cubic inches of water 16.) PART A: 15w > or equal to 120; w > or equal to 8 weeks
PART B: the number of weeks is reduced; 65 + 15w > or equal to 120; w > or equal to 3 and 2/3 weeks.
