Title: Credit Unit 5 Introduction
Course: SkillsCom MTH 111 14.0 > Section: Credit Unit 5 Module 1

You have made it to the last Credit Unit in College Algebra and you are almost finished! In this last Credit Unit, the focus is on linear systems of equations and then a recap of the key topics in College Algebra. Most of you will be continuing on to Calculus, so we want to be sure you remember all of the important topics.

We will start off with solving systems of 2 or more variable equations by hand, using  the addition and elimination methods. There will be application problems to set up and solve. It is important to recognize when a system of equations has an inconsistent solution or a dependent solution. This part of the material may be a review.

Then we move on to looking at systems of equations as augmented matrices; we will translate systems of 2 or more equations into augmented matrices and then use our graphing calculators to solve a system of equations. You are going to LIKE that part!

There will be a quick introduction into the algebra of matrices: adding and subtracting matrices, scalar multiplication with a matrix, multiplication of two matrices, finding the inverse of a square matrix and recognizing when each of these operations is defined. Technology will be used as needed and appropriate.

Last will be an overview of the important topics to take with you into MTH241. This will be a review of the key algebraic functions and their graphs, the vocabulary associated with functions and function notation and a review of a variety of algebraic equations and applications.

Course Outcomes:

- Recognize and identify the different types of functions (linear, polynomial, radical, inverse, rational, exponential, and logarithmic) by making connections between the graphical behavior, numerical patterns, and symbolic representations.
- Apply algebra skills to solve equations including linear, polynomial, radical, rational, exponential, and logarithmic expressions, and also linear systems of equations.
- Use a graphing calculator and/or other technology to solve college algebra problems.
