Answer:
0,0
Step-by-step explanation:
if you substitute the X and Y from the answer choices into each equation and check if they're true only 0,0 is true for both.
having all the necessary or appropriate parts:
Answer:
The determinant of the matrix given is -49
Step-by-step explanation:
We are given determinant ![\left|\begin{array}{ccc}4&2&-1\\3&0&4\\-3&1&1\end{array}\right|](https://tex.z-dn.net/?f=%5Cleft%7C%5Cbegin%7Barray%7D%7Bccc%7D4%262%26-1%5C%5C3%260%264%5C%5C-3%261%261%5Cend%7Barray%7D%5Cright%7C)
The determinant can be found as follows
![4\left|\begin{array}{cc}0&4\\1&1\\\end{array}\right|-2\left|\begin{array}{cc}3&4\\-3&1\\\end{array}\right|-1\left|\begin{array}{cc}3&0\\-3&1\\\end{array}\right|](https://tex.z-dn.net/?f=4%5Cleft%7C%5Cbegin%7Barray%7D%7Bcc%7D0%264%5C%5C1%261%5C%5C%5Cend%7Barray%7D%5Cright%7C-2%5Cleft%7C%5Cbegin%7Barray%7D%7Bcc%7D3%264%5C%5C-3%261%5C%5C%5Cend%7Barray%7D%5Cright%7C-1%5Cleft%7C%5Cbegin%7Barray%7D%7Bcc%7D3%260%5C%5C-3%261%5C%5C%5Cend%7Barray%7D%5Cright%7C)
Now solving:
![4(0-4)-2(3+12)-1(3+0)\\=4(-4)-2(15)-1(3)\\=-16-30-3\\=-49](https://tex.z-dn.net/?f=4%280-4%29-2%283%2B12%29-1%283%2B0%29%5C%5C%3D4%28-4%29-2%2815%29-1%283%29%5C%5C%3D-16-30-3%5C%5C%3D-49)
So, determinant of the matrix given is -49
The 5 is the coefficient...
