Document Summary
There are 6 problems on two pages in this examination. Problem 1. a) use gauss-jordan elimination (reduced row echelon form) to solve the system of linear equations x +y +2z w = x y x +2y +3z 3w = 5 or explain why the system is inconsistent. If the system is consistent, write down the solution in a vector form. No credit will be given, if any other method is used: determine if the vectors. Determine if the vector is a linear combination of the vectors. Given three points a = (1, 2, 3), b = ( 1, 5, 0) and c = (2, 3, 2): write parametric equations of the plane containing points a, b and. C: determine if the triangle with the vertices a, b and c is acute, obtuse or right triangle. Determine if the given matrix c is elementary matrix or not.
