System of equations and inequalities

  1. OPEN ENDED Give a system of equation that is more easily solved by substitution and a system of equations that is more easily solved by elimination.
  2. OPEN ENDED Write an example of a system of three equations in three variables that has (-3, 5, 2) as a solution. Show that the ordered triple satisfies all three equations.
  3. OPEN ENDED Create a system of inequalities that forms a bounded region.
  4. Writing in Math Use the information about buoy tenders on page 158 to explain how linear programming can be used in scheduling work. Include a system of inequalities that represents the constraints that are used to schedule buoy repair and replacement and an explanation of the linear function that the buoy tender captain would wish to maximize.

For #4, page 158 is in the attachment.
