Ms. O'Malley wrote this equation on the board and asked, "Is this a true equation?" x – y = y – x

Lindsey said, "Sometimes it is, and sometimes it isn't."

For each case shown, determine whether this equation is true or false. Check the box if the case is always true.

Question 5 options:

x ≠ 0, y = 0

x = 0, y = 0

x = 0, y ≠ 0

x ≠ 0, y ≠ 0

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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.
