Answer:
x = -5, y = -6, z = -3
Step-by-step explanation:
Given the system of three equations:

Write the augmented matrix for the system of equations

Find the reduced row-echelon form of the augmented matrix for the system of equations:

Thus, the system of three equations is

From the last equation:

Substitute it into the second equation:

Substitute y = -6 and z = -3 into the first equation:

Answer:
Thank you very much :) needed that
Well you'd see if it's closer to 10000 or 20000.
In this case it would round to 20000.
Between 2 and 3, should be somewhere before .5
Answer:
I can get you jump started a bit.
Step-by-step explanation:
So Each of those pairs of figures are Similar.
This means they have equal angle measures but different side lengths.
To find it, we have to make a <u>Proportion:</u>
<u>Example: #11</u>
