WebProof of 'only-if' part Let rank ( A) = n. Since RREF ( A) is row-equivalent to A , RREF ( A) = R A, where R is an invertible matrix. Since rank ( A) = n, all rows of RREF ( A) = R A are non-zero. Since R A is a square matrix in RREF, R A = I n . Since R is invertible, all left inverses of R are the same as all right inverses of R . tennis recycling and trash mnWebT is a linear transformation so T (x) can be written as a linear combination of the vectors T (e1) and T (e2).
