Document Summary
Please read all instructions carefully before beginning: each problem is worth 10 points. In parts (c) and (e), a denotes an m n matrix (m rows and n columns), and in (e), is a vector in rm. In (b) (e), circle t if the statement is necessarily true, and circle. F otherwise: what is the best way to describe the solution set of the equation x +2 y z = 0? a line in r2 a line in r3 a plane in r2 a plane in r3, t. It is possible for the matrix equation ax = 0 to be inconsistent. The following matrix corresponds to a linear system with one free variable: The solution set of ax = b is empty or it is a translate of a span in rm. 1: find a vector in r3 that is not in span1. Consider the following picture of two vectors v, w: d b c v.
