Question

-210 A and B are sxs -Thabis_ matruos ALEL 15-7 and you get ather exchanging R and hy OFA AL=6 ix Changes the a matrix Changes Columns of Exchanging rows or colum Sign s is the mentax you put after multiply - By oth by -10 3 b and then ob. B then machplying R factor (-30) = 210 by a given HB, 1 = /B1 (3X-10) = B =-7 (-30) = 3 multiplying a row or a column by age alters the determinant by that factor. de is the result of adding 2Rz to -Rs in s esult of adding 2Rz to -Rs in B to get a mw x5 1 lal= -7 or column does not Adding or substracting to a row Change the determinant A is the result of cuddling Lor, a A to 6 Ry of A. XLÅ L = 6. Adding or substracting to arow or coluwn doesn't Change the determina n. ③ A is a 3x3 matrix where Az = [] and Ax= [ 1 ] what do you know A AX=3 HAT=58 about A ? J X = AT IX - 4 matres nosente, Bouwhat does this man ?

Answer 1

Roku & Ritz of A AT A, is you get puterchanging A, l= -9 IAI= IAL=6 B, 8 B, is matrix you get after multiplying Ri of B by 3 l лил в 1 в Бу (-6) )) - -1) (-3) = to a C, is the result of adding ar to - Rg An B to get on hero . h5 lie Rot-kgtgR3 ( new changes change is only of (-Rs) •е Те, 1 - t-s' t&| -|-- (2 ) |

loh, of A to bru of i is the result of adding - 2 веч pala 6(141) = 6063 36
