2/14 Algebra 1 - Systems of Inequalities...Cont'd

Welcome back after the long weekend & snow day! Today we continued our work with systems of inequalities. Unfortunately, the computer demonstration did not work Friday when I was absent, but the process was explained again today anyway. To review graphing linear inequalities, watch the video from above. All you do with a system of inequalities is repeat the process for the second inequality, and whatever area is shaded twice is your solution. The assignment given on Friday can be turned in for extra credit.

A note about the Website & Extra Credit

All extra credit will now be available through the website only. It will be given by leaving comments on the website. As you work through the homework, use the website as a resource. If you find something useful, one of the demos answered a question or you discovered something while doing the homework, leave a comment on that day's post. All you have to do is click on the "Post a Comment" or "0 Comments" at the bottom of a post. When you enter your name, use your first name & last initial. The Comment page is shown above. Type your message. Click the 'Other" button and leave your name. Also, there is a new help feature located in the sidebar at the right. The small chat module will tell you if I am online at home, and if you have a question over a homework problem, I can talk you through it. Again use your first name and last initial. Please make sure comments are appropriate and related to that day's post.

2/14 Algebra 2 - Solving Radical Equations

Welcome back after our holiday weekend and snow day! The blog is back in action after a layoff since Thursday. Today in Algebra 2, we continue with Chapter 7. We will be solving radical equations today. Radical equations are equations that contain a root or fraction exponent of some kind. Above, you can see a simple example of how to solve one of these. Students will take notes, as usual, in class showing some example problems and how to solve them. After some discussion and a few practice problems at the board, students will work on the graded assignment. Below is another example of how to solve a radical equation. This one has a root on both sides of the equation.
