Answer:
5
Step-by-step explanation:
Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.
Then, if A is a matrix the maximum number of pivots that can have is one by row, that is, 5.
Then the maximum rank that A can have is 5.
Start with
Add 2x to both sides:
Subtract 21 from both sides:
Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:
So, the answer is
