J=3,1 and 0,5 K=1,0 and 0,-2 L=1,3 and 0 M=3,-3 and 0,-2 N=4,6 and 0,5
Answer:
4 and -6≤x<0
Step-by-step explanation:
6. 4
7. -6≤x<0
W - 2 = -3
w = -3 + 2 added 2 to both sides
w = -1
hope this helps, God bless!
Cramer's rule tells you that the value of x in the system of equations

is given by

In matrix terms, this is the determinant of the coefficient matrix with the right-side constants replacing the x-coefficients divided by the determinant of the matrix of coefficients. The value of y can be found by doing similar math with the numerator being the determinant of the coefficient matrix with the right-side constants replacing the y-coefficients. For systems of higher dimension, the column of right-side coefficients replaces each column of variable coefficients in turn.
For your equations, this evaluates to
