A banker has a retirement portfolio that increases at a particular rate per year. The total amount, in dollars, in the portfolio can be modeled by the equation. y = p (1 + q )x What is the meaning of the parameter p in this model? It is the amount in the portfolio after x years. It is the initial amount in the portfolio. It is the number of years the banker has had the portfolio. It is the rate of change for the portfolio per year.

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.
