A car service charges customers a flat fee per ride (which is higher during rush hour traffic) plus charges for each minute and each mile. Suppose that, in a certain metropolitan area during rush hour, the flat fee is $ , the cost per minute is $ , and the cost per mile is $ . Let x be the number of minutes and y the number of miles. At the end of a ride, the driver said that the passenger owed $ and remarked that the number of minutes was times the number of miles. Find the number of minutes and the number of miles for this trip. 2 0.40 1.30 21.80 five Complete the equation that represents the total cost of the ride.

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.
