Math 116 - Chapter 5 Study Guide

  1. Solve the system of equations by the method of substitution. One linear system, one non-linear system. Look at problems 5.1.15-28, 41-42, 49-50.
  2. Find the system of linear equations that has the given solution. There is more than one possible solution. One part has an ordered pair, the other part has an ordered triplet. Look at problems 5.2.57-60, 5.3.41-44.
  3. Use a graphing calculator to approximate all points of intersection of the graph of the system of equations. One system involving transcendental functions, one non-linear system. Look at problems 5.1.37-50.
  4. Use back substitution to find the solution to the system of equations. Look at problems 5.3.5-10.
  5. Find the equation of a parabola passing through three points. The model y=ax2 + bx + c is given. Write a system of linear equations that can be used to find the equation of the parabola, solve the system of equations, then write the equation of the parabola. Look at problems 5.3.85-88.
  6. Sketch the graph of the inequality. Look at problems 5.4.9-20.
  7. Sketch the graph of the solution of the system of inequalities. Look at problems 5.4.39-50.
  8. Solve the system of equations by the method of elimination. Two parts. Look at problems 5.2.11-20.
  9. Solve the system of linear equations. Show your work. One is a three by three system of linear equations, the other is a two by three system of linear equations. Look at problems 5.3.13-21, 33-38.
