Chapter five was all about matrices. We learned how to use our calculators and to do the math in our head. it was about solving equation sets and also graphing them on our calcs and on a number line. We learned about the determinant and the inverse of a matrice. mr.s. rakova really made us notr only use our calculator but learn how to do it in our heads.

Chapter 5 was a very interesting chapter. We learned a lot about how to solve systems of equations. It began with teaching about inequalities and compound sentences. Next, we learned about solving systems using tables and graphs. After that we learned how to solve systems by using substitution, then linear combinations, and inverse matrices. After completing the different ways to solve systems, we began to learn about graphing inequalities in the coordinate plane. Next, we learned about the graphing and solving of linear inequalities. Chapter 5 was very informative.

Chapter 5 was about matrices. We learned how to multiply them, use them in equations, and solve linear equations with them. We also learned about linear combinations and solving them through different methods. We had to learn to do a lot of math in our heads, but we also learned how to use our calculators to solve the problems as well as graph inequalities.

We also learned about inequalities and compound snebtences. We reviewed how to graph them on a number line and on a graph. The chapter also explained ways of solving systems. It explained how to solve using tables, graphs, substitution and linear combinations. LIke Margo said we also used matrices to solve systems.Another aspect of ch. 5 was graphing inequalities in the coordinate plane. We also learned about how to get the solutions to a system of linear inequalities called a feasible set

Chapter five was all about systems: how to graph them, solve them by using linear equations and solve them by using matrices. We also learned all about inequalities. I didn't find this too hard.

In chapter 5 I learned how to solve inequalities with substutition, and linear combinations. I also learned that when you multiply or divide by a negative number the enequality is switched. I learned how to graph enequalities with open or closed circles. I also learned how and where to shade when I am graphing an enequalitiy.It really helped get a chance to try to do the problems without a calculator, because of the no calculator section

In Chapter 5 we learned how to solve systems using subsitution, linear combinations, matrices, and graphs. We also learned how to solve matrices of all sizes and how to make line graphs and use them to solve simple equations.

I thought that chapter five was rather easy. I found the concept of metrices was easy to learn. In chapter 5 we learned about inequalities and compound sentences. Then we learned about solving systems using tables or graphs. Then we learned how to solve systems using substitution. Then we learned how to solve systems using linear combinations. After that we had to memorize how to figure out how to get the inverse of a matrice. After that we learned how to solve a system using metrices. After learning how to graph inequalities in a coordinate plane, we learned the systems of linear inequalities. Basically, in this lesson we learned how to solve systems in many ways. I thought that all the ways were pretty easy, and i got a very good grade on the test.

In chapter 5, we learned about inequalities and how they pertain to compound sentences, and how they can be solved by tables and graphs, substitution, and linear combinations.Also, matrices were introduced as a stem from chapter 4. The idea of inverse matrices was introduced. Solutions can be solved by matrices. The inequalities were graphed in the coordinate planes. It was actually an interesting chapter because it introduced a variety of different concepts, yet related them to each other and added on to information learned inthe previous chapters.

Chapter 5 taught us how to solve equality and ineqaulity equations by using substitution, linear combinations and graphing. This was not necesarily an easy thing to do but chapter 5 also taught us how to use matrices to solve such problems. Besides learning how to do such functions on our calculator, our teacher also encouraged us to do such work in our heads. Although Chapter 5 was tedious work, it did teach us a lot in using variables and linear equations as well as many ways to solve and interpret the results.

Chapter five was about solving systems of equations. It was ver interesting because we learned that you can make a system of two or more equations from almost any word problem to make solving it easier. We used four main ways of solving the systems; subsitution, linear combinations, graphing, and matrices. With matrices we had to do the work in our head, and we also learned how to do it on a calculator. We learned how to use determinants and inverse matrices to help solve the system. We also learned how to graph equations using < and > signs.
