A. Reading Data Charts B. Solving Systems

A. Matrix is a rectangular arrangement of numbers into rows and columns 1. Dimensions read row x column 2. Address is read through location B. Rows are numbers which are across C. Columns are numbers which are up and down D. Scalar is a real number that multiplies each entry

Identify the matrix of the following:

A. Add them like integers and correspond to the same entry B. Must have same number of rows and columns

Solve

Given the following below, solve for B – A

Given the following below, solve for A – B

Given the following below, solve for 2A – 3C

Just like distribution property

Solve

Given the following below, solve for 2A – 3C

Solve

Given,
