Representing Constraints

Constraint: a restriction or limitation on either the input or output values

1. Determine whether the coordinate (-2, -17) is a solution to the equation y = 5x - 7.

2. Determine whether the coordinate (-2, 9) is a solution to the inequality y ≤ 5x + 6.

3. Julia has $6.50 to spend on peaches and apples at the farmer’s market. She bought 4 peaches at $0.75 each. How much money can she spend on apples? Write a system on inequalities that represents this situation.

4. A taxi company charges $2. 50 plus $1. 10 for each mile driven 4. A taxi company charges $2.50 plus $1.10 for each mile driven. Write an equation to represent this situation. Use this equation to determine how far you can travel if you have $10.00. What is the minimum amount of money you will spend?

5. A school supply company produces wooden rulers and plastic rulers 5. A school supply company produces wooden rulers and plastic rulers. The rulers must first be made, and then painted. It takes 20 minutes to make a wooden ruler. It takes 15 minutes to make a plastic ruler. There is a maximum amount of 480 minutes per day set aside for making rulers. It takes 5 minutes to paint a wooden ruler. It takes 2 minutes to paint a plastic ruler. There is a maximum amount of 180 minutes per day set aside for painting rulers. Write a system of inequalities that models the making an then painting of wooden and plastic rulers.

6. Use the system of inequalities created in #3 to give a possible solution to the system.

7. A sport goods company produces figure skates and hockey skates 7. A sport goods company produces figure skates and hockey skates. One group of workers makes the blades for both types of skates. Another group makes the boots for both types of skates. It takes 2 hours to make the blade of a figure skate. It takes 3 hours to make the blade of a hockey skate. There is a maximum of 40 hours per week in which the blades can be made for both types of skates. It takes 3 hours to make the boot of a figure skate. It takes 1 hour to make the boot for a hockey skate. There is a maximum of 20 hours per week in which boots can be made for both types of skates. What are the possible combinations of the number of figure skates and hockey skates that can be produced given the constraints of this situation?
