Use the determinant feature of a graphing calculator to solve the system by Cramer's rule . (Round to one decimal place.)
-1.5x + 3.1y - 2.3z + 0.6w = 2.7 6.1x - 0.5z - 3.4w = 0.8
11.5y - 2.2w = 0
4.0x + 3.0y - 2.1z = 9
A) {(3.6, 1.1, 4.1, 5.6)}
B) {(3.2, 1.0, 3.7, 5.0)}
C) {(7.9, 2.4, 9.0, 12.3)}
D) {(4.3, 1.3, 4.9, 6.7)}
