Larson Algebra II - Chapters 3 & 4 Vocabulary

A method of solving a system of equations where the “value” of one variable is inserted into the other equation and solved for the single variable

• elimination

• substitution

• rotation

• reflection

A system of equations that does not have a unique solution but has infinitely many solutions

• matrix

• translation

• inconsistent system

• dependent system

The rectangular array of numbers used as the “opposite” to “undo” multiplication in an matrix equation

• inverse matrix

• translation

• identity matrix

• equal matrix

A system of equations that has no solution

• inverse matrix

• reflection

• inconsistent system

• dependent system

A process for solving systems of equations where one equation is added to another equation to “remove” one variable and allow to solve for the other. Then, the first variable is substituted to find the second

• elimination

• transformation

• dilation

• substitution

The rectangular array of numbers which, when multiplied by a matrix, produces the original matrix

• reflection

• identity matrix

• inverse matrix

• image

Values of x, y, and z that represent a location of a point in 3-dimensinoal space

• determinant

• ordered triple

• matrix

• scalar

Two or more equations with two or more of the same variables

• dependent system

• inconsistent system

• equal matrices

• system of equations

The fixed point around which a figure is turned

• scalar

• determinant

• center of rotation

• scalar

In a matrix, ad-bc, used as the denominator in a scalar for multiplication in finding the inverse matrix

• determinant

• scalar

• dilation

• translation
