Are You Smarter Than a Fifth Grader? 1

Stay focused and work out each problem in your notebooks 2

Copy problems into your notebook and SHOW ALL of your work!! 3

The review is only as good as you make it…..so make it your best! 4

5 Evaluate the expression for x = 2 and y = -2 3x 2 - 4(y + 1) 16

6 Bill’ construction company builds 3 houses a month. Use the expression 3m (where m = # of months) to determine How many houses are built in 36 months. 108

7 Graph the point (4, -2) on a coordinate graph? What are the coordinates of point B?

8 Express the relation in a table and state the domain and range: {(5, 4), (2, 8), (-3, 0), (3, 2), (4, 7)} X 5 2 -3 3 4 Y 4 8 0 2 7 Domain: 5, 2, -3, 3, 2 Range: 4, 8, 0, 2, 7

9 Express the relation as a graph and state the domain and range. Also, is the graph continuous or discrete? {(5, 8), (1/2, 4), (-3, 6), (0, 0), (-10, 3)} Domain: 5, ½, -3, 0, -10 Range: 8, 4, 6, 0, 3 Discrete

11 223, 243, 263, 283, …….. Put the sequence into a chart: 1 2 3 4 5 6 223 243 263 283 303 323 Write an expression that could be used to find the nth term 20n +203 What is the 99 th term of the sequence? 2183

12 Write an expression that can be used to find the nth term of the sequence: -8, -3, 2, 7, ….. 5x - 13

13 Write an algebraic expression to represent the data in the graph 625m Use the expression to find the total budget for 15 months. \$9375

14 The phone company charges a monthly fee of \$35 and an additional \$0.45 per minute of phone usage. Make a table for the total cost during month for 10, 25, 55 and 90 minutes of calls. minutes (m) 10 25 55 90 Cost (c) 39.50 46.25 59.75 75.50 Write an equation to model the total charge (c) for any given number of minutes. C = 0.45m + 35

16 Which equation represents the linear Relationship between x and y shown In the table? X 0 1 2 3 Y 5 8 11 14 a. Y = -3x + 5 b. Y = -3x + 2 c. Y = x + 2 d. Y = 3x + 5 d

17 A regular octagon has all 8 sides congruent. The relationship between the side length of a regular octagon, s, and its perimeter, P, Can be modeled by the function P = 8s. Find the missing side Length in the table below: Side length (s)Perimeter (P) 1 8 3 24 5 40 ???? 64 8

18 Graph the function y = -3x + 5 Is this graph continuous or discrete? continuous

19 Graph the function y = x 2 + 1

20 Determine if the following chart of data represents a linear or non-linear function, and……how do you know? Yes, same common difference

21 Howard is raising money for his school by selling baseball caps. The amount of money, y, that he needs to reach his goal depends on the number of baseball caps, x, that he sells. This is represented by the equation y = 800 – 15x. What does the 800 represent? a.Price of each baseball cap b.Howard’s sales goal c.Number of baseball caps d.Number of baseball caps to sell B
