Find the difference. Jeremy is practicing some tricks on his skateboard. One trick takes him forwards 3 feet, then he flips

around and moves backwards 7.2 feet, then he moves forward again for 4.2 feet.

What expression could be used to find how far Jeremy is from his starting position when he finishes the

trick?

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.
