Do the matrixes of
-1 4 3 5
2 0 -6 1
multiplyed by
2 0
1 4
3 -2
-5 1
equal -3/4? Thanks, I just want to confirm that my answer is right (or wrong)
To determine if the matrices are multiplied correctly and if the result is -3/4, we need to perform the matrix multiplication.
The given matrices are:
Matrix A:
-1 4 3 5
2 0 -6 1
Matrix B:
2 0
1 4
3 -2
-5 1
To multiply matrices, we need to follow the rule for matrix multiplication: the number of columns in the first matrix must match the number of rows in the second matrix.
Matrix A has 2 rows, and Matrix B has 2 columns, so the multiplication is possible.
To find the resulting matrix, we multiply each element of a row in Matrix A by the corresponding element in the column of Matrix B, and then sum up the products.
Multiplying the matrices, we get:
-1 * 2 + 4 * 1 + 3 * 3 + 5 * (-5) = -2 + 4 + 9 - 25 = -14
-1 * 0 + 4 * 4 + 3 * (-2) + 5 * 1 = 0 + 16 - 6 + 5 = 15
So, the resulting matrix is:
-14
15
The calculated result is not equal to -3/4. Therefore, the answer is wrong, and the matrices do not multiply to give -3/4.
