Today we had a substitute teacher (Mr. Reechai). I don’t know how to spell his name and I didn’t bother asking. The test is scheduled for Wednesday… so I’m just going to go over some review for the test. If you have forgotten what the types of systems there are then I will tell you. The first system is a Consistent system and will have an ordered pair solution. The next system is the Inconsistent system that will have no solution because the lines never cross. The last system will be the Dependent system that can have an infinite amount of solutions because the lines are superimposed and are always crossed.

I have also found some good links to website’s that may help you in prepping for the test.

Well that is my post and I have no idea who the scribe is for tomorrow.

We began the class with what we do every class, Mental Math. After the Mental Math was done the class moved on to learning about Systems of Equations. There are 3 possible solutions. The first solution is called an ordered pair solution, were the parabola's cross. This is called a Consistent System. The next system is called an Inconsistent System, this includes parallel lines that never cross leaving this system with no solution. The third and last system is called the Dependent System. The Dependent System has superimposed lines (one line on top of the other), there are an infinite amount of solutions for both lines.

Also, questions 1-3 on page C-3 in the new package we had been given today must be done for homework. P.S. Richie48 is the next scribe.
