Finite Math Homework Assignments – Part 1
General Directions
Throughout the semester, always carefully follow the directions on the homework assignment sheet. Show all
your work. The more work you show me, the more partial credit I can give you. Unless otherwise directed, give
exact answers in fraction form or round answers to 3 decimal places. On cycle-back problems (which are
required, not optional), follow the directions from the original assignment. Always check your answers against the
back of your textbook (for odds) or the instructor’s manual (for evens).

Chapter 3:
Graph carefully and accurately. Make your graphs large enough to clearly see the feasible
region. Graph paper is not required, but it is highly recommended. Include a t-chart with a
minimum of three points (preferably the x and y-intercepts and a point between them) with the
graph of every oblique line. Mark one notch on each axis to indicate the scale you are using.

Chapter 4:
When solving linear programming problems using the simplex method, use Method 2, i.e. get a
one in the pivot position before you pivot. Record all slack or surplus equations, record all
manual row operations (i.e. 21 R3, 3R1 + R2), circle the pivot in each matrix, and record all
matrices. Clearly state your conclusion.
