Write the augmented matrix for each system of equations. 7x-9y+3z=6
-2x-6y+10z=3
-3x-5y+5z=-1

Do not comment if you aren’t going to . create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?

Typically a point in a three dimensional cartesian coordinate system is represented by which of the following answers in the picture !
