Which system of equations has two solutions? Select one: Match each system of equations with the number of solutions. a. y -2x2--4X -2 y=-x2-3 y=-4 Choose... y = - 2X - 5 x + 2y =2 4 3x -zy Choose.. y- -X3 y = - 2x+1 2x + 3y = 1 3y -25-2x Choose. O CE My - -x2-4 y -3 y = = 2x+ 1 3x-9 = 3y Choose.. two solutions O d. y =x7+4 infinitely many solutions y = 2x+ 2 student is asked to solve the following system of equations using substitution: 2x+y = -1 Time left 2:41:27 x-y =1 State the solution(s) of the system of equations represented by the graph. Identify a possible third equation that must be solved to find the sofation using substitution Not yet answered Marked out of Select one: 1.00 O a. -2x+ (x -1) = -1 O b. - 2x + (x -1) =1 O c. - 2(1 -y )+y= =1 O d. - 2(y - 1) +y= -1 Select one : O a. (-3, -2). (0, 1) O b. (-1,2) (-3, -2). (0. 1), (-1. 0) O d. (0,1), (-1, 0) ine number line that Illustrates the solution to x2 + 3x - 4 2x2 - 5x - 6, the test point (2, -8) of Select one: O d. 20x + 2y = 2 10x + 4y = 6 O A. can be used to determine the solution region because it lies on the boundary O B. cannot be used to determine the solution region because it does notelle on the bou O C. cannot be used to determine the solution region because it lies on the boundary O D. can be used to determine the solution region because it does not be the boundary Clear my choice
