5 0

Answer:

-(20+z)/y = x

Step-by-step explanation:

-20=xy +z

Subtract z from each side

-20 -z = xy+z-z

-20 -z = xy

Divide each side by y

(-20 -z)/y = xy/y

Factor out a negative

-(20+z)/y = x

Suppose matrix B is the inverse of matrix A. Use your knowledge of inverses and matrix multiplication to answer the following: A
neonofarm [45]

AB will be an Identity matrix.

<h3>What is an identity matrix?</h3>
  • A square matrix with 1s on the main diagonal and 0s everywhere else is an identity matrix.
  • The identity matrices 22 and 33, for example, are presented below.
  • These are known as identity matrices because they produce the identity matrix when multiplied by a compatible matrix.
  • If the answer to a matrix multiplication problem is an identity matrix, then each of the two matrices is an inverse matrix of the other.
  • When the matrix is multiplied by the original matrix, the result is the identity matrix.

As it is given in the description itself, if the answer to a matrix multiplication problem is an identity matrix, then each of the two matrices is an inverse matrix of the other.

Therefore, AB will be an Identity matrix.
