Expanding the walls of our classroom. This is an interactive learning ecology for students and parents in our Algebra 2 class. This ongoing dialogue is as rich as YOU make it. Visit often and post your comments freely.
Here are some Problems from chapter 3 that I am using to study I will post the problems and then we can all post the answers to the different problems as comments and that way we are colabrating!
3.1 Solve each inequality giving its solution set in both interval and graph forms. Check your answers. 27. 2/3 (3k-1) is greater than or equal to 3/2(2k-3)
Solve each inequality giving its solution set in both intervals and graph forms. Check. 45. -3 is less than or equal to 3m+1/4 is less than or equal to 3
47. Use the graph in the book to complete this word problem Distance runners prefer cool temperatures. During what time period are temperatures predicted t be no more than 70 degrees F? Use the lower forcast boundary.
3.2 For each compound inequality state whether intersection or union should b used. Then give the solution set in both interval and graph forms. 53. x+1 is greater than or equal to 5 and x-2 is less than or equal to 10
For each compound inequality state whether intersection or union should b used. Then give the solution set in both interval and graph forms. 55. -3x is less than or equal to -6 or -3x is greater than or equal to 0
27. 2/3 (3k-1) is greater than or equal to 3/2(2k-3) 2k-2/3 is greater than or equal to 3k-9/2 -k is greater than or equal to -23/6 k is less than or equal to 23/6 Set form=(negative infinity,23/3]
53. x+1 is greater than or equal to 5 and x-2 is less than or equal to 10 x is greater than or equal to 4 AND x is less than or equal to 12. [4, infinity) and (negaitive infinity,12]

10z+7>0
10z>-7
z>-7/10
10z+7<0
10z<-7
z<-7/10
(negative infinity,-7/10), (-7/10, infinity)
