In a certain video game, players earn bonus points after finishing a level. The number of bonus points is based on how many seconds, t, it takes the player to finish the level. The game uses -5.5 + 500 + 0.9t + (11/2 - 1.9t) to determain the number of bonus points . Zaraha finishes a level in 201 seconds. How many bonus points does she earn?

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.
