Augmented Matrix
An augmented matrix contains the coefficients and constants from a system of equations.
Determinant
The determinant of a square matrix is a real number that can be computed from its elements according to a specific formula.
Dilation
A dilation is a transformation that can change the size of a figure. When the center of the dilation is the origin, you can use scalar multiplication to find the coordinates of the vertices of an image.
Equal Matrices
Equal matrices are matrices with the same dimensions and equal corresponding elements.
Image
An image is a figure obtained by a transformation of a preimage.
Matrix
A matrix is a rectangular array of numbers written within brackets. A matrix with m horizontal rows and n vertical columns is an m X n matrix.
Matrix Addition
You add two matrices with the same dimensions by adding their corresponding elements
Matrix Element
Every item listed in a matrix is an element of the matrix. An element is identified by its position in the matrix.
Matrix Equation
A matrix equation is an equation in which variable is a matrix.
Matrix Multiplication
If A is an m X n matrix and B is an n X p matrix, then the product matrix AB is an m X p matrix.
Preimage
The pre image is the original figure before a transformation.
Row Operations
To solve a system of equations using an augmented matrix, you can use one or more of the following row operations: switch any two rows, multiply a row by a constant, add one row to another, combine one or more of these ships.
Scalar Multiplication
Scalar multiplication is an operation that multiplies a matrix A by a scalar c. To find the resulting matrix cA, multiply each element of A by c.
Variable Matrix
When representing a system of equations with a matrix equation, the matrix containing the variables of the system is the variable matrix.
Zero Matrix
It is the additive identity matrix for the set of all m X n matrices.
