Question 18Correct8.75 points out of 8.75Flag questionQuestion textSolve the system using Gaussian elimination or Gauss-Jordan elimination.2(x- 2z) = 3y+ x+ 30x= 2y- 2z- 3-5x+ 2y+ 6z= -41
Question 19
Incorrect0.00 points out of 8.75Flag questionQuestion textSolve the problem.An accountant checks the reported earnings for a concert venue for three different performers against the number of tickets sold. Let x, y, and z represent the cost for children tickets, student tickets, and general admission tickets, respectively. Set up an augmented matrix for the system and solve for x, y, and z. Explain what the accountant knows about the reported earnings.Select one:a. {(8, 8, 17)}; There were $8 children's tickets, $8 student tickets, and $17 general admission tickets sold.b. { }; The system of equations reduces to a contradiction. There are no values for x, y, and zthat can simultaneously meet the conditions of this problem.c. {(7, 7, 16)};There were $7 children's tickets, $7 student tickets, and $16 general admission tickets sold.d. {(6, 6, 15)}; There were $6 children's tickets, $6 student tickets, and $15 general admission tickets sold.FeedbackThe correct answer is: { }; The system of equations reduces to a contradiction. There are no values for x, y, and zthat can simultaneously meet the conditions of this problem.
