Chloe and Bao are in motorboats at the center of a lake. At time t-0, Chloe begins traveling south at a speed of 55 km/h. One minute later, Bao takes off, heading east at a speed of 45 km/h. At what rate is the distance between them increasing at t = 11 min? (Round your answer to three decimal places.) ds km/min dt

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.
