Wich statement is true about the order pair (-1,5) x+y=4
x-y=-6

A. The order pair (-1,5) is a solution to the first equation because it makes the first equation true

B. The ordered pair. (-1,5) is a solution to the second equation because it makes the second equation true

C. The ordered pair of (-1,5) is not a solution to the system because it makes at least one of the equations false

D. The ordered pair (-1,5) is a solution to the system because it makes both equations true

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

i think the answer is b.

step-by-step explanation:

not 100% sure though.

i think it is 18

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.
