Elementary Algebra

revised 2019-01-26
Unit 8A

TOPIC: Applications of 2x2 Linear Systems & Solving Linear Systems Electronically (including 3x3)

  • Check for new Class Announcements and your Clark Student Email.

  • Read Lesson Notes #5.4 and Lesson Notes #5.6

    LN #5.6 "Supplementary Resources" contains important information about using technology to solve 3x3 systems.

  • MyMathLab: Study e-text sections 4.4-4.5

    In section 4.5 SKIP any examples that "solve 3x3 system algebraically" and solve electronically instead.

  • Note: Section 9.4 (graphing linear inequalities and solving systems of linear inequalities) I've made optional (not covered on any quiz/exam). However students planning to take Finite Mathematics (Math 105) are urged to study this material on their own (over a break).

  • WAMAP: Post a substantive response to DQ 8 on DB8 due by noon Wednesday. (4 pts toward CPRs.)
