For a system of vectors U = {(1,2,9 ); (2,3, 1);(0,-1,1-9);(2,3,10);(1,0,2-9) } . a. Find the number of dimensions and a basis W of the subspace generated by the vector system U .
b. Find the parameter k so that u = (2,3,k3+1) is a linear combination of W , and deduce [ u]W .

to have more of what you want like money

step-by-step explanation:

save it by not spending on unnecessary stuff and have more

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.
