Determine the number of solutions. 2x+3y=6. and -6x-9y=-18

There are 0 solutions

Step-by-step explanation:

I graphed this equation and they are parallel lines so since they will never touch there is no solution. Another way to figure this out is by finding the slop and seeing is it's parallel or perpendicular but graphing it is just faster for me! The picture below is what the graph looks like so you have a visual. Hope this helps!

step-by-step explanation:

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.
