Question 113

Multiple Choice

Provide an appropriate response.
-For a certain system of three linear equations, the solution set is {5,19,2}\{ 5 , - 19 , - 2 \} , and D=13D = 13 . Find the values of DXD _ { X } , Dy\mathrm { D } _ { \mathrm { y } } , and DZ\mathrm { D } _ { \mathrm { Z } } .


A) DX=247;Dy=65;DZ=26\mathrm { D } _ { \mathrm { X } } = - 247 ; \mathrm { D } _ { \mathrm { y } } = 65 ; \mathrm { D } _ { \mathrm { Z } } = - 26
B) DX=5;Dy=19;DZ=2\mathrm { D } _ { \mathrm { X } } = 5 ; \mathrm { D } _ { \mathrm { y } } = - 19 ; \mathrm { D } _ { \mathrm { Z } } = - 2
C) DX=65;Dy=247;DZ=26\mathrm { D } _ { \mathrm { X } } = 65 ; \mathrm { D } _ { \mathrm { y } } = - 247 ; \mathrm { D } _ { \mathrm { Z } } = - 26
D) DX=135;Dy=1319;DZ=132\mathrm { D } _ { \mathrm { X } } = \frac { 13 } { 5 } ; \mathrm { D } _ { \mathrm { y } } = - \frac { 13 } { 19 } ; \mathrm { D } _ { \mathrm { Z } } = - \frac { 13 } { 2 }
