Check you answer by computing C = AB − I, where I is the identity matrix

Which of the following is true for matrices?Review Later(AB)-1 = B-1A-1(AT) = AAB = BAA*I = I

Consider the matrices and  .Calculate .

his question come from Bradley (2008, pp. 495–496, Progress Ex-ercises 9.2). Let I2 be the (2 × 2) identity matrix, and consider thefollowing three matrices:A =( 1 −40 9), B =( 4 3−7 0), and C =( 5 −1 −112 0 2).(a) If possible, find A + B.(b) If possible, find A − B.(c) If possible, find A + 4B.(d) If possible, find A + I2.(e) If possible, find AI2.(f) If possible, find A + C.(g) If possible, find A + BT .(h) If possible, find BC.(i) If possible, find CB.(j) If possible, find CBT .(k) If possible, find (AB)T .(l) If possible, find C + 5I2.(m) If possible, find CT A.(n) If possible, find (BC)T .(o) If possible, find AC + B
