It's quite difficult, almost impossible to write all steps to solve a 3x3 matrix.
However, I will give you te answer that is determinant (Matrix)=54
Answer:
Step-by-step explanation:
Now here's the important result of doing all of this: Notice how all of the repeating decimal parts have subtracted away to zero! We are left with a nice, simple 7481 on the right side of the equal sign.
Now, solving 9999x=7481 for x by dividing both sides of it by 9999, we'll get that x=7481/9999. And this is your answer.
Completing the square gives
At the point on the graph along the axis of symmetry, the squared term vanishes, so that when 
, we have 
. So
