... All the nonzero rows of the row echelon form form a basis for the row space: thus a basis for the row space is {(1,0,1,2), (0,1,01,2), (0,0,1,5)} For a basis of the column space, take the columns of the original matrix with leading 1 in the row echelon form: take the first 3 columns. Thus a basis f ...

... common intersection point of all the equations’ graphs − and there are only 3 ways a set of lines could intersect.) If the vector b on the right-hand side is the zero vector, then the system is called homogeneous. A homogeneous linear system always has a solution, namely the all-zero solution (that ...

... b) State the contrapositive of the statement. Is the contrapositive true or false, and why? Solution: The contrapositive is “If x is parallel to y, then kx + y k = kxk + kyk.” The contrapositive is false since it is equivalent to the original statement, which is false. c) State the converse and inve ...
