86, 91, 98, 83, 97, 89, 99, and 96
Which inequality describes the score the ninth student must make for the class to qualify for the pizza party? 16% Picked C 10% Picked B 59% Picked D 11% Picked A Test Hint: Perimeter means you need to add up all the sides, so you are being tested on distributing and combining like terms. A hexagon has two sides with lengths 2x + 1, two sides with lengths 3x - 2, and two sides with lengths 4x - 5. Express the perimeter of the hexagon in terms of x. B. 9x - 6 16% Picked B C. 18x3 + 10 11% Picked C D. 18x - 16 9 % Picked D A. 18x - 12 61% Picked A What simplified expression could be used to find the area of the shaded region?

D: -3 ≤ x ≤ 2 ; R: -2 ≤ y ≤ 4 C. D: -3 ≤ x ≤ 2 ; R: -3 ≤ y ≤ 6 D. D: -3 ≤ x ≤ 2 ; R: 0 ≤ y ≤ 4 Test Hint: The line curves so make sure you include all the x and y values that the graph represents 14% Picked B 79% Picked D Three students solved an algebraic equation. Who has solved the equation correctly? Test Hint: Solve the equation and then match your answer. F. No One G. Mia H. Molly J. Jared 12% Picked H 17 % Picked G 24% Picked J 46% Picked F Find the length of a rectangle with perimeter 30 meters and width 4 meters.
l = P = 2l + 2w Test Hint: You are being tested on evaluating an equation. You can either use your store feature on your calculator or plug the equation into your y = screen and use the table feature to solve using the x value they gave you. Use whatever method works best for you. In the quadratic equation x2 - x + c = 0, c represents an unknown constant. If x = 3 is one of the solutions to this equation, what is the value of c? c = Test Hint: Place the equation for nonmembers in y1 and place the equation for members in y2 , then use the table feature to find where the two equations equal each other. The unknow variable is the number of videos a customer will rent, therefore the x-value represents the number of rented videos. The is the same when a customer rents Suppose a video store charges nonmembers $4 to rent each video. A store membership costs $21 and members pay only $2.50 to each video. For what number of videos is the cost the same? videos. Test Hint: Remember there will be a variable rate that is connected to the x - value and a fixed rate that will either be added or subtracted to the end of the equation. To identify the variable rate look for words such as: Each A Per Denise's cell phone plan is $29.95 per month plus $0.10 per minute. Denise's cell phone bill is $99.95. For how many minutes was she billed? Write the equation out and then solve using the two - step method. She was billed for minutes. Find the product (-2x) (x2 - 3x + 9) F. -2x3 - 3x + 9 G. -2x3 - 6x2 + 18x H. -2x3 - 6x2 - 18x J. -2x3 + 6x2 - 18x Please feel free to take this practice test as many times as you need. I will have to reset the practice exam for you, so come by during tutorials or before / after class.
