Schools A and B are competing in an academic contest. Correct answers earn 10 points. Incorrect answers lose 6 points. In the final round, School A gives the same number of correct and incorrect answers. School B gives no incorrect answers and the same number of correct answers as School A. School A started the final round with 186 points. School B started with 96. The game ends with the two schools tied. Let x represent the number of correct answers given by School A in the final round.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
