Solutions of Systems of Linear Equations

Description: Fundamental concepts of Algebra; equations and inequalities; functions and graphs; polynomial, rational,
exponential and logarithmic functions ; systems of equations and inequalities; conics; the Binomial Theorem. Credit not
granted in both MATH 143 and MATH 147.

Pre-requisites: C or better in Math 108 OR placement recommendation from COMPASS (Algebra Score of 62 or
greater), ACT (Math Score of 23 of greater) or SAT (Math Score of 540 or greater)

Required Textbooks and Supplies: College Algebra Third Edition Robert Blitzer, Prentice Hall, 2001, ISBN 0-13-
087828-6; a scientific calculator with log and exponential functions (You won’t have to pay more that $12 for this type of
calculator); a small stapler (for your homework)

Course Objectives: The student will demonstrate knowledge of: complex numbers; linear, quadratic, and certain other
equations; linear, quadratic, and rational inequalities ; lines and slope ; parallel and perpendicular lines and circles ;
functions and their graphs; transformations, compositions, combinations, and inverses of functions; quadratic and
polynomial functions and their graphs; polynomial division ; the remainder and factor theorems; finding zeros of polynomial
functions; rational functions and their graphs; modeling using variation; exponential and logarithmic functions and their
properties; exponential and logarithmic equations; using modeling with exponential and logarithmic functions; systems of
linear equations in two or three variables; systems of nonlinear equations in two variables; systems of inequalities; linear programming; ellipses, hyperbolas, and parabolas ; and the binomial theorem.

Library Use: The CSI Library is an excellent place to find further information about topics in mathematics. The computers
in the library are available for your use in finding information from the card catalog and the internet as well as sending
email. Student Email Account If you don't currently have an email address, every registered student has a web-based
student email account.  if you do not have a middle initial or did not use it when registering at the Records Office, you need to use an x instead) Your password is your full Social Security Number as given to CSI, no spaces or dashes.
Example: John Doe who was born May 7th with social security number 555-00-1111 You can access this account anywhere that you can find access to the web: at home, in a public library, in a computer lab, etc.

Policies and Procedures:
a. Attendance is important for your success in this class and homework/quiz scores will be used to track attendance.
Even if you don't have the assignment done, you should turn in a page with your name and the chapter and section. If
missing class is unavoidable, please make arrangements with a classmate to get notes.
b. Homework assignments and their due dates will be emailed after class each day. I will occasionally give a pop quiz
instead of collecting the homework. Since I use homework/quizzes as a record of attendance, late homework will not be
accepted and make-up quizzes will not be given, no matter what the reason. From time to time, circumstances may force
a student to miss class. I recognize this and will drop your four lowest homework /quiz scores. Homework that is not neatly
written on loose-leaf paper (without spiral edges) may receive a grade of zero. All of the pages that correspond to an
assignment should be stapled. If you do complete a homework assignment late and would like to know the answers, come
see me during office hours. If you are going to miss class because of required attendance at a verified school activity, you should turn in your completed assignment ahead of time and prepare the assignment that will be due upon your return to
c. 5 regular exams and 1 comprehensive final will be given during the semester. There will be NO makeup exams
given. If you must miss a test, that exam score will be dropped and replaced by your final exam score. Although I plan to
give tests in class, I reserve the right to give tests in the Campus Testing Center (GRM 230).The Campus Testing Center
hours are Mon. - Thurs. 8:00 am - 9:30 pm. You cannot start a test after 8:30 pm. On Friday, the hours are 8:00 am – 5:00
pm. You cannot start a test after 4:00 pm. Photo ID is required every time. The testing center does not make exceptions!
d. Grades will be calculated as follows: the homework/quiz average (after dropping the lowest 4) will be 1/7 of your grade. Each of the first five tests will be 1/7 of your grade. The final will make up the remaining 1/7 of your grade.
90 - 100 is an 'A', 80 - 89 is a 'B', 70 - 79 is a 'C', 60 - 69 is a 'D', and below 60 is an 'F'
e. Please read the behavioral policies starting on page 16 of the current CSI Catalog. Any violation of these policies will
be dealt with severely, including but not limited to, being dismissed from the class and/or given a grade of "F" for the
f. Cell Phones that ring or cause other disruptions will not be tolerated. If you anticipate that a child, friend, spouse, etc. may need to call you because of an emergency and your cell phone cannot be set to alert you silently, you should arrange for the caller to dial CSI security at 732-6605. Failure to respect the rights of others in the class will in most cases lead to a verbal warning on the first offense and a grade of “F” and/or withdrawal from the class if the problem persists.
g. Any student with a documented disability may be eligible for related accommodations. To determine eligibility and
secure services, students should contact the coordinator of Disability Services at their first opportunity after registration for a class. Student Disability Services is located on the second floor of the Taylor Building on the Twin Falls Campus.
h. Resources for Help: 1. Free drop-in tutoring in the Math Lab in Shields 207; see schedule on the door there. 2. Free
drop-in tutoring for developmental math at the Math Help Desk in Library 202; call Nate Kelsey 732-6548 for schedule. 3.
Get a free Peer Tutor; call Nate Kelsey 732-6548 for application information. 4. Form a study group with others in the
class; to reserve a study room in the library, call 732-6500. 5. Check out Math 143 Videos on reserve in the library; ask at the circulation desk.
i. I reserve the right to correct errors or omissions in this syllabus.

Outcomes Assessment: Homework will be assigned, graded, and analyzed. Five tests and a final will be administered
and the results compared to course objectives. As part of departmental analysis of outcomes in this course and its place
in the Mathematics program, student completion of the pre-requisite, success in the current course, success in
subsequent courses and student satisfaction will be reviewed by the instructor. A report containing this information will be submitted by department faculty to determine what, if any, changes can be made to improve the course in terms of
content, focus, and instruction.
