Alluisi Production Copyright Norfolk Public Schools, 2006 Animations from www.gifs.net Directions • For each question you get correct you get 2 points. • For each incorrect answer that you select, the computer gets 1 point. • Your goal is to beat the computer’s score. Lets get started! A repairman estimated the cost of replacing a part in Mrs. James’ computer would be at most $225. The estimate included $35 for the part, a $40 service charge, and $30 per hour for labor. What is the maximum number of hours the repairman estimated for the job? 4½ 5 5½ 6 Correct! 2 points What is the solution to the following equation? 4x – 1 = 2x + 5 x=1 x=2 x=3 x=4 Correct! 2 points What are the x- and y-intercepts of the line with equation 4x + 5y = 40? x-intercept 10, y-intercept 8 x-intercept 8, y-intercept 10 x-intercept -10, y-intercept -8 x-intercept -8, y-intercept -10 Correct! 2 points Which is an equation for the line that passes through the origin and has a slope of 3/5? y = 3/5 x = 3/5 y=x y = 3/5x Correct! 2 points What is the slope of the line y = 4x – 2? 4 2 ¼ -2 Correct! 2 points The difference in cost between a large bag of chips and a small bag of chips was 90¢. Alicia bought 5 large bags and 3 small bags of chips for her party and spent $17.22. What was the cost of a small bag of chips? $5.74 $2.49 $2.15 $1.59 Correct! 2 points The length of a rectangle is 6 meters more than its width. If the area is 135 square meters, what is its width? 5m 9m 15 m 27 m Correct! 2 points Which is a solution to the following equation? x2 – 12x – 28 = 0 x = 14 x = 12 x=2 x=0 Correct! 2 points What is the slope of the line through (3,2) and (-1, -4)? 3 3/2 2/3 -3/2 Correct! 2 points x2 – 3x = 0 Which is the solution set for the equation above? {0, 3} {-3, 0} {1, 3} {2, 3} Correct! 2 points What is the value of 4m + 8 4m + 4 when m = 4? 0.5 1.2 1.7 2.0 Correct! 2 points Which expression is equivalent to -4a(3a – 5b)? -12a2 = 20ab -12a2 – 20ab -12a2 + 20a -12a2 + 9ab Correct! 2 points Which is equivalent to (2a + 3b – 2c) + (3a – 4b – c) + (a – 5b + 4c)? 5a – 6b + c 6a – 6b - c 6a – 6b + c 6a2 – 6b2 + c2 Correct! 2 points Which equation best represents the line shown? y = 2x + 2 y = 2x + 1 y = ½x + 2 y=x+2 Correct! 2 points What is the apparent slope of the line graphed? 5/2 2/5 -2/5 -5/2 Correct! 2 points The numbers in the table follow a linear pattern. x y 2 14 4 26 6 38 8 50 28 170 30 ? What is the missing y value? 182 180 176 172 Correct! 2 points The table below shows the relation between the number of members in a club selling cookies and the predicted number of boxes sold. Number of Members, g Number of Boxes Sold, b 5 350 10 650 15 950 20 1,250 Using the data shown above, which equation could be used to predict the number of boxes of cookies that the club will sell? b = 60g b = 70g b = 60g + 50 b = 50g + 50 Correct! 2 points The cost of fabric varies directly with the amount of fabric purchased. If 1 2/3 yards of fabric cost $10.00, how much would 4 ½ yards cost? $45 $27 $24 $14 Correct! 2 points If m varies directly as p, and m = 5 when p = 7, what is the constant of variation? 35 12 7/5 5/7 Correct! 2 points The stem-and-leaf plots show the number of miles per gallon a family’s car and truck averaged over the past few months.
