SV#5 Unit J Concepts 3-4: Solving Matrices

   

This is Ana from Period 4                                
This Is  Doctor Problem #5. The things that we must be aware at and pay close attention to is that when I am looking for the zero i always use the row that is above it to turn it into a zero. Also, make sure that by the end we create a triangle of zeroes at the bottom and a down step of ones. Also when checking for your answer in the graphing calculator you use matrx, edit, and make sure it is a 3x4 scale and write the correct numbers in. Then we press second quit and matrx again, math and search for RREF. then select A and close the parenthesis. When checking for your answer the values of x, y, z will be listed vertically.

I hope this video helped. Thank You for watching.
