Calculate the inverse of the matrix and find the values for a, b, c, and d [4,12,1,10] A^1=[a/14,b/7,c/28,d/7]

a: 5

b: -3

c: -1

d: 1

Step-by-step explanation:

Given the matrix:

A = [4   12

       1   10]

its determinant is: 4*10 - 1*12 = 28

the inverse of A is:

1/28*[10  -12

        -1    4]    

[10/28  -12/28

-1/28    4/28]    

A^-1 = [5/14  -3/7

          -1/28  1/7]

take it another

i dont know sorry
