Solve Systems using Substitution C. Solve Systems using Elimination D. Applications of Systems E. Graphing Linear Inequalities F. Solving Systems of Linear Inequalities Solve the following problems to practice these above concepts. Use a pencil and show work. For #1 & 2, solve the system graphically: 1. = = 2 = = 4 3. Describe the three different types of systems: a). Consistent and Independent: b). Consistent and Dependent: c). Inconsistent for #4 & 5, solve the system using substitution: 4. = 2 5. = = = 15

4 For #6 & 7, solve the system using elimination: = = = = 12 For #8 10, solve using any algebraic method. Write a system and define your variables. 8. A corner store sells two kinds of baked goods: cakes and pies. A cake costs $15 and a pie costs $6. In one day, the store sold 12 baked goods for a total of $108. How many cakes id they sell? 9. Sharon has some one-dollar bills and some five-dollar bills. She has 14 bills. The value of the bills is $30. Solve a system of equations to find how many of each kind of bill she has. 10. At the local ballpark, the team charges $8 for each ticket and expects to make $1,100 in concessions. The team must pay its players $2,100 and pay all other workers $1,200. Each fan gets a free bat that costs the team $4 per bat. How many tickets must be sold to break even? For #11 & 12, graph the solution to the system of linear inequalities: < 1 < > 24

5 Chapter 7 Exponents & Exponential Functions In your flip book complete the following topics. Write necessary formulas, information, and draw diagrams: G. Laws of Exponents H. Scientific Notation I.

For #13 16, simplify each expression: 13. " (6 ) Last year, a large trucking company delivered tons of goods with an average value of $20,000 per ton. What was the total value of the goods delivered? Write the answer in scientific notation. 20. Suppose a population of 200 crickets doubles in size every month. The function = gives the population after months. How many crickets will there be after 3 years?

6 For #21 & 22, provide a table and graph the exponential function: 21. = = 23. Suppose the population of a town is 19,000 and is growing 2% each year. Write an exponential growth function and predict he population after 11 years. 24. A tractor costs $15,100 and depreciates in value by 9% per year. Write an exponential decay function and predict how much it will be worth after 9 years. 25. Suppose that the amount of algae in a pond doubles every 3 hours. If the pond initially contains 50 pounds of algae, how much algae will be in the pond after 8 hours? 26. Steve invests $4000 in a money market account that pays 1.25% interest compounded monthly. Use the compound interest formula to find how much will be in the account after 4 years. 27. Shelly invests $10,000 in a money market account that pays 2.5% interest compounded annually. Use the compound interest formula to find how much will be in the account after 12 years.
