Patterns, Relations, and Functions Jamal wants to save $75.00 for a new bike. He thinks he can save $5.00 each week. Make a table to show how many weeks it will take him to save the money for the bike. A.4.5.1

Patterns, Relations, and Functions Find the missing term in the function table provided by your teacher. A.4.6.1

Patterns, Relations, and Functions The rule “multiply by 2 and add 1” can be written as y = 2x + 1. Use the rule provided by your teacher to create and complete a function table. A.4.7.1

Patterns, Relations, and Functions For the following questions, use the algebraic equation provided by your teacher. 1. Find the value of y if x = Identify the independent and dependent variables. 3. State the y-intercept and slope of the equation. A.4.8.1

Algebraic Representations 1.How many halves are in the number 3? 2.Use your answer to step 1 and the factor 3 to write a mathematical sentence. 3.How many halves are in the number 4? 4.Use your answer to step3 and the factor 4 to write a mathematical sentence. 5.In your own words, write a relationship between multiplication and division. NO.2.4.2, A.5.4.1

Algebraic Representations A variable is a letter representing an unknown quantity. If you are using x as your variable, three more than x can be written as x + 3. Choose a variable for your unknown. Write an expression to represent three less than your variable. A.5.5.2
