Pivot the system about the element in row 2, column 1. (enter the augmented matrix with all cells in their original position.)

3 3 | 6

4 3 | 5

We have the system

The augmented matrix of the system is

Pivot the system means to use row operations for find the echelon form of the augmented matrix.

Then,

1. In the second row of A we subtract 4/3 from the first row. We obtain:

Then B is the echelon form of A.

We use backward substitution to find the set of solutions.

1.

2.

The system has unique solution

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

leave feedback if u need : )

yes, i heard the "tea" with james charles and a few other beauty gurus. i believe charles is in the wrong and i believe tati the most. tati didn't lie about james charles but may have exaggerated because he never sexually assaulted anyone. jeffery star is a really good friend to all and out anyone that needs it, until you mess with one of his "sisters"! james will never rise over jeffery or tati, he's way to sensitive and dramatic to rise about them. i think all three of them will make up and be friends again because they always get over it.

i hope this with your
