We then reviewed solving a system of equations by substitution and learned a new method, solving by elimination (lesson, pdf).
Your homework for Friday is:
- In the lesson (pdf) on Atomic Weights, we got as far as solving for H. Try to complete that problem by substituting in the value of H into either original equation and then find C, then check it in the other equation. We'll go over this on Friday.
- Prepare for the Solving Systems of Equations by Graphing Assessment. There are a variety of ways to do that including, but not limited to: review the online pre-assessment; review your notebook and/or the openers and lessons posted on the blog; review the video, work some practice problems in your textbook or that you find online. You can, of course, also get help from me, another math teacher, a teacher in the Study Center, a peer tutor in the Study Center, or a parent, sibling or friend. Do whatever works best for you, but make sure you're prepared. The expectation is that you should all be able to do very well on this assessment.
