A pattern of rectangles is formed by decreasing the length and increasing the width each by the same amount. The
relationship between x, the amount of increase, and A, the area of the rectangle represented by the increase, is
quadratic
Which graph could represent the area of each rectangle in terms of the change in the length and width?

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.
