How many pivot columns must a 7x5 matrix have

WebTranscribed Image Text:Suppose A is a 7x5 matrix. How many pivot columns must A have if its columns are linearly independent? Why? If A had fewer pivot columns, then the equation Ax=0 would have only the trivial solution. O A. OB. The matrix must have WebThe matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. D. The columns of a 5x7 matrix cannot span R5 because having more columns than rows makes the columns of the matrix dependent. Previous question Next question.

WebSpan. Span of column space the linear combination of all the columns of the given matrix. For linear combination of n vectors the linear independence of the vector plays a important role which will be used to solve the problem. WebSo here a column vector of a five by seven would have 12345 entries because there are five rows. So basically what three and four says is that us This matrix, the five by seven matrix would span are five. If there was a pivot if there was a leading pivot in every row. So that means that there must be five pivot positions. the owl house cz titulky https://dogwortz.org
