The answer is 9/10
1/109
It is a.
is it 4 inverse of mod 17 or whole inverse? Whole inverse do not make sence, so, ans for the q is 13.
Usually there is an inverse key or( tan -1 )key for this
it is used to find the inverse of the matrix. inverse(A)= (adj A)/ mod det A
The answer depends on what you mean by "opposite": whether it is the additive inverse or the multiplicative inverse.
To find the inverse of a number, you take its reciprocal. For a non-zero number ( x ), the inverse is ( \frac{1}{x} ). If you are looking for the additive inverse, it is simply the negative of the number, which is ( -x ).

The fact that the matrix does not have an inverse does not necessarily mean that none of the variables can be found.

You can factorize the matrix using LU or LDLT factorization algorithm. inverse of a diagonal matrix (D) is really simple. To find the inverse of L, which is a lower triangular matrix, you can find the answer in this link.www.mcs.csueastbay.edu/~malek/TeX/Triangle.pdfSince (A T )-1 = (A-1 )T for all matrix, you'll just have to find inverse of L and D.
