9-7 Solving Systems of Linear and Quadratic Equations – We learned to describe a linear-quadratic system of equations and solve this system of equations by graphing, elimination, or substitution. For any system of two equations in two variables the solution consists of the ordered pairs that satisfy both equations.
10-1 Perimeter and Area – We reviewed the concept of the number of faces, edges, and vertices in 3 dimensional shapes. Then we completed a 3-D shape maze where we answered questions and followed the answer to solve the next problem until we got to the end of all the boxes.
Topic 2 Mid-Topic Checkpoint – We learned to use mathematical modeling to represent a problem situation and to propose a solution. Then we learned to test and verify the appropriateness of our math models. Next we discovered that many real-world problem situations can be represented with a mathematical model, but that model may not represent a real-world situation exactly.
Andrew continued exercises from his Algebra I, Prentice Hall textbook, rearrange multi-variable equations. He also practiced several multiplication facts.
Ben continued exercises from his Algebra I, Prentice Hall textbook, relate the graph of the equation to solutions. He also practiced several multiplication facts.
9-6 The Quadratic Formula and the Discriminant – We learned that the quadratic formula can be used to solve every quadratic equation and is particularly useful for those that cannot be easily factored. Then we learned to use the discriminant to determine the number and type of solutions to a quadratic equation.
