Quizplus · Accepted Answer

The correct response involves finding the determinant of the coefficients matrix from the system of equations given by u and v. The determinant is calculated as $|A| = (2)(4) - (5)(5) = 8 - 25 = -17$. The question seems to ask for the reciprocal of this determinant, thus the correct answer is $- \frac { 1 } { 17 }$.
