Who'd be better at speed answering? Datguy323 or some Helping Hand? (Not a serious question) Solve for the variables:

x = 3

y = 1

Step-by-step explanation:

The equations are:

and

Putting second equation in the first one:

=>

Subtracting 27 to both sides

=>

=>

Taking power 7 to both sides

=> y = 1

Now,

Taking cube root on the both sides

x = 3

(3,1)

Step-by-step explanation:

First, to find x, simply take the cube root of 27, or 3.  Thus, x = 3.

Then, simply plug it in:

Thus, y = 1

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.
