Question 317

Multiple Choice

Provide an appropriate response.
-For a certain system of three linear equations, the solution set is {6,1,7}\{ 6,1 , - 7 \} , and D=17D = - 17 . Find the values of DX,Dy\mathrm { D } _ { \mathrm { X } } , \mathrm { D } _ { \mathrm { y } } , and DZ\mathrm { D } _ { \mathrm { Z } } .


A) Dx=6;Dy=1;Dz=7\mathrm { D } _ { \mathrm { x } } = 6 ; \mathrm { D } _ { \mathrm { y } } = 1 ; \mathrm { D } _ { \mathrm { z } } = - 7
B) DX=17;Dy=102;Dz=119\mathrm { D } _ { \mathrm { X } } = - 17 ; \mathrm { D } _ { \mathrm { y } } = - 102 ; \mathrm { D } _ { \mathrm { z } } = 119
C) Dx=102;Dy=17;DZ=119\mathrm { D } _ { \mathrm { x } } = - 102 ; \mathrm { D } _ { \mathrm { y } } = - 17 ; \mathrm { D } _ { \mathrm { Z } } = 119
D) DX=176;Dy=17;DZ=177\mathrm { D } _ { \mathrm { X } } = - \frac { 17 } { 6 } ; \mathrm { D } _ { \mathrm { y } } = - 17 ; \mathrm { D } _ { \mathrm { Z } } = \frac { 17 } { 7 }
