An triangle has vertices A, B, C as shown in the diagram. It has been translated vertically and/or horizontally to the triangle with vertices labelled A', B', and C' using a translation matrix defined as T. y A B A' B' Which of the following matrices is T? OF = 32 22 22] Or = OF = 2 2 7 3 ] FinishFrom the list of equations: 1. y = 2x - 1 2. y = 2x - 2 3. y = 2x + 1 4. 2y = 4x - 2 Which pair of equations forms a system that has infinitely many solutions? O 1 and 4 O 1 and 2 O 2 and 4 O 2 and 3 Given the matrices below, 4 = [8 2] if D = A + C, then the element d21 is: 0 6 O 15 O 12 O 33If A= - 6 4 , find A - 1 . 1 - A O A-1 = 2 Solve the system of equations defined by Ax + 3y = 10 5x + 4y = 13 using matrices. it: [8 8] x - [19] The value of y is O - 2 O 2 O 1 O 3 Ashley and Stephanie went shopping for Father's Day at the same store. Stephanie spent $70 for 5 cans of tennis balls and 3 sleeves of golf balls. Ashley bought 2 cans of tennis balls and 5 sleeves of golf balls for $85. What was the cost of a can of tennis balls? (Hint: The equation for Ashley's purchases is 27 + 5G = 85 First determine the equation for Stephanie's purchases and then solve the system of equations using matrices.) $4 for tennis balls $5 for tennis balls $4.25 for tennis balls $3 for tennis balls
