Modeling/Multiple Representation: Question 1 of 25
 What is the image of point (2,5) under the translation that shifts (x,y) to (x+3,y-2)? (0,3) (0,8) (5,3) (5,8) Correct Answer Number: 3 Explanation: For the point that you are given (2,5), 2 is the x-coordinate, and 5 is the y-coordinate. Simply substitute x=2 and y=5 into the new translation (x+3,y-2). You will get (2+3, 5-2) which is (5,3). More Information

Modeling/Multiple Representation: Question 2 of 25
 The direct distance between city A and city B is 200 miles. The direct distance between city B and city C is 300 miles. Which could be the direct distance between city C and city A? 50 miles 350 miles 550 miles 650 miles Correct Answer Number: 2 Explanation: Picture the three cities forming a triangle. (According to the answers, the three cities do not form a straight line.) The sides of a triangle are related in such a manner that the adding of any two sides of the triangle must give a value larger than any single side of the triangle. The value 350 is the only choice that will uphold this relationship. More Information

Modeling/Multiple Representation: Question 3 of 25
 At a concert, \$720 was collected for hot dogs, hamburgers, and soft drinks. All three items sold for \$1.00 each. Twice as many hot dogs were sold as hamburgers. Three times as many soft drinks were sold as hamburgers. The number of soft drinks was 120 240 360 480 Correct Answer Number: 3 Explanation: Represent the number of hamburgers by x. The cost of a hamburger is one dollar times x, which is still represented by x. Since they all sold for the same amount of money, the cost of the hotdogs is represented by 2x and the cost of the soft drinks is 3x. Your equation is x + 2x + 3x = 720. Solving for x, you will get 6x = 720 and x = 120. BE CAREFUL!! The question asks for the number of soft drinks or 3x.

Modeling/Multiple Representation: Question 4 of 25
 If x = -3 and y = 2, which point on the graph below represents the location (-x,-y)?   P Q R S Correct Answer Number: 2 Explanation: (-x,-y) = (-(-3),-2) = (3,-2) More Information

Modeling/Multiple Representation: Question 5 of 25
 The diagram below shows triangle ABC with segment AB extended to point D, exterior angle CBD measuring 145º, and angle C measuring 75º. What is the measure of angle CAB?   35º 70º 110º 220º Correct Answer Number: 2 Explanation: Since angle ABC and angle DBC form a straight angle, the measure of angle ABC=35º. The angles in a triangle add to 180º. Therefore the measure of angle CAB=70º. This problem could also be done using the exterior angle theorem: The exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles. More Information

 The image of the point (5,6) reflected in the y-axis is (6,5) (-6,5) (5,-6) (-5,6) Correct Answer Number: 4 Explanation: Draw a sketch and fold along the y-axis. Your new point is in the 2nd Quadrant. It is the same distance away from the y-axis as the original point (5,6). More Information

Modeling/Multiple Representation: Question 9 of 25
 If the sides of a triangle are 6, 8 and x, how many integer values of x could be the measure of the third side of the triangle? 11 5 6 8 Correct Answer Number: 1 Explanation: Remember that the sum of any two sides of a triangle must be larger than the third side. The third side could be as small as 3, or as large as 13, and still make this rule true. This is a total of 11 values. More Information

Modeling/Multiple Representation: Question 10 of 25
 The distance between parallel lines p and m is 12 units. Point A is on line p. How many points are equidistant from lines p and m and 8 units from point A? 1 2 3 4 Correct Answer Number: 2 Explanation: This is a compound locus problem. Do each part separately and see where the results intersect. First, the points equidistant from the two parallel lines is a third parallel line half way between the two given lines (in this problem, 6 units from each line). Draw this line as a dotted line. Second, the points equidistant from point A form a circle of radius 8. Draw the circle dotted. Look for the intersections of the dotted drawings. The dotted circle intersects the dotted line in two places. More Information

Modeling/Multiple Representation: Question 12 of 25
 The distance from point A to point B is seven units. How many points are equidistant from A and B and also four units from point A? 0 1 2 3 Correct Answer Number: 3 Explanation: This is a compound locus problem. Do each part separately and find the points of intersection. First, the points equidistant from A and point B form a line half way between A and B (the perpendicular bisector of segment AB). In this problem, this line is 3.5 units from both A and B. Draw this line dotted. Second, the points equidistant from point A form a circle of radius 4. Draw the circle dotted. Look to where the dotted line and the dotted circle intersect (2 locations). More Information

Modeling/Multiple Representation: Question 13 of 25
 Two supplementary angles are in the ratio of 2 to 3. The number of degrees in the smaller angle is: 18 36 54 72 Correct Answer Number: 4 Explanation: Supplementary angles add to 180º. Represent the angles as 2x and 3x. 2x + 3x = 180 and 5x = 180 therefore x = 36. BE CAREFUL!! The question asked for the smaller angle (2x). 2x = 72. More Information

 Triangle ABC is congruent to triangle DEF with segment AB congruent to segment DE. If AB = 2x + 10, and DE = 4x - 20, find the value of x. 5 10 15 60 Correct Answer Number: 3 Explanation: Congruent means equal. 2x+10=4x-20 30=2x 15=x More Information

Modeling/Multiple Representation: Question 15 of 25
 The two legs of a right triangle measure 5 and 12. The leg and hypotenuse of another right triangle measure 12 and 13 respectively. What can be said about these two triangles? The triangles are congruent. The triangles are not congruent. The triangles are both equilateral triangles. The triangles are both isosceles triangles. Correct Answer Number: 1 Explanation: In the first triangle with legs of 5 and 12, the hypotenuse is 13 (use the Pythagorean Theorem). In the second triangle with leg 12 and hypotenuse 13, the missing leg is 5 (use the Pythagorean Theorem). These triangles are exactly the same size and shape (congruent). More Information
