If the equation Ax = 0 has only the trivial.solution, then A is row equivalent to the nxn identity matrix. noose the correct answer below. O A. The statement is true. By the Invertible Matrix Theorem, if equation Ax = 0 has only the trivial solution, then the equation Ax =b has no solutions for each b in R^. Thus, A must also be row equivalent to the O B. The statement is false. By the Invertible Matrix Theorem, if the equation Ax =0 has only the trivial solution, then the matrix is not invertible. Thus, A cannot be row equivalent to the n× n identity matrix. OC. The statement is true. By the Invertible Matrix Theorem, if the equation Ax = 0 has only the trivial solution, then the matrix is invertible. Thus, A must also be row equivalent to the nxn identity matrix. trhial nolution then the matriy is not invertible: this means the columns of A do not span R". Thus, A must also be

Matrices

‘Matrices’ is the plural form of the word matrix, and it is basically a spreadsheet in the form of a box. In mathematics, various functions can be carried out with matrices. Generally, a matrix comes in the shape of a square or rectangle. The elements are distributed horizontally in the form of rows, and vertically in the form of columns.
