The Attempt at a Solution
I need help with the second question, I did the first one correctly. My pre board is on Monday so please help.
Matrices are used to represent and manipulate data in various fields such as mathematics, physics, and computer science. They are also used in solving systems of equations and in transformations in geometry.
To add or subtract matrices, you must make sure that they have the same dimensions (same number of rows and columns). Then, simply add or subtract corresponding elements of the matrices to get the resulting matrix.
No, in order to multiply two matrices, the number of columns in the first matrix must be equal to the number of rows in the second matrix. The resulting matrix will have the same number of rows as the first matrix and the same number of columns as the second matrix.
To find the inverse of a matrix, you must first make sure that the matrix is square (same number of rows and columns). Then, use the Gauss-Jordan elimination method to reduce the matrix to its row echelon form. The resulting matrix will be the inverse of the original matrix.
A row matrix is a matrix with only one row, while a column matrix is a matrix with only one column. They both have the same number of elements, but the order of the elements is different. In a row matrix, the elements are arranged horizontally, while in a column matrix, the elements are arranged vertically.
