O -10 x < -2 X>-2 y < -2 y> -2 OT 5 LA 11 10 QUESTION 14 How many solutions does the system, infinitely many none one none of the above 3x + 4y = 12 6x + 8y = - 12' have? QUESTION 15 What is the solution to this graphed system of linear equations? (0,0) (4.-1) (-1.4) no solution -5 y LO 6 -10 10 x Solve the system, (0, 3) (3, 0) (-3,0) (0, -3) 22 and 44 QUESTION 17 The sum of two numbers is 66. The larger number is 2 more than 3 times the smaller. What are the two numbers? 20 and 46 18 and 48 16 and 50 [2x+y = 3 y=x+3 QUESTION 18 Solve the system, (-/, 4) (4,-2) (-2, 4) , by substitution. -2x+y=9 2x+4y=11' by elimination, and then write the answer as an ordered pair (x, y). QUESTION 19 3 points Save Answer Four times a number, x, plus five times a number, y, equals 79. Ten times x minus 5 times y equals 5. Find the numbers by setting up a system of linear equations and solving the system using the elimination method. x=7.y=9 x=6, y = 11 x = 8, y = 10 x = -10, y = 7 QUESTION 20 Which point is a solution to this graphed system of inequalities? 10 (1.4) (-43) (-1, -3) (-6. 1) -5 y 10 No -5 -10 in 10 X
