Which of the following is the correct way to perform matrix multiplication between matrices x and y?   Question 6 options:   dot(x,y)   cross(x,y)   x*y   x.*y Matrix multiply A times B in that order. What is the value in row 1, column 1 of the result of the multiplication? A = [1 3 5;      2 4 6]; B = [-2  4;       3  8;      12 -2];   What is the dot product of A and B? A = [1 3 5] B = [-3 -2 4] I want to matrix multiply M times another matrix. How many rows does the other matrix need to have? M = [1 3 5;      2 4 6;      9 2 1;      7 3 1]; I calculated the determinant of a matrix  and got 0, so...   Question 11 options:   The matrix does NOT have an inverse   The matrix has an inverse Fill in the blank to calculate the determinant of M. M = [7 2;      1 1] ___________   Question 12 options:   determinant(M)   determin(M)   det(M)   deter(M)   Question 13 (1 point)                 I calculated the determinant of a matrix  and got -4, so...   Question 13 options:   The matrix does NOT have an inverse   The matrix has an inverse
