Let A12 and b4 14 (a) Find A-1 and use it solve the four equations Ax-b1, Ax b2 Ax b3, and Ax b4 (b) The four equations in part (a) can be solved by the same set of operations, since the coefficient matrix is the same in each case Solve the four equations in part (a) by row reducing the augmented matrix [A bj b2 b3 b4

answer: haha (: i’ll go see what it is

step-by-step explanation:

stop cheating

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
