The graph of f is shown. The x y-coordinate plane is given. The graph labeled y = f(x) is made up of 4 connected line segments.
The first line segment starts at the point (0, 5) on the y-axis, goes up and right, and ends at the point (10, 15).
The second line segment starts at (10, 15), goes horizontally right, and ends at the point (15, 15).
The third line segment starts at the point (15, 15), goes down and right, crosses the x-axis at x = 25, and ends at the point (35, −15).
The fourth line segment starts at the point (35, −15), goes up and right, and ends at the point (45, −10).

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
