The following graph shows a system of inequalities. Is the point (2,2) a solution?
Yes, the point is a solution
No, the point is not a solution.

Yes, the point is a solution.

Step-by-step explanation:

A system of inequalities displayed on a graph has two shaded regions, and for this example, one is red and the other is blue. The region that contains all the solutions to the system of inequalities is where the two regions intersect to usually form a new color, which in this case is purple. We can see that the point (2,2) is located within the purple region, so therefore, yes, the point is a solution.

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.
