True or false if a linear system has no solution, the rank of the coefficient matrix must be less than the number of equations.

Step-by-step explanation:

Given that a linear system has no solution.

If a system of equations is represented by

Ax=B

where A = matrix formed by coefficients and B the constants

Wwhenever A is singular we find that either the system has no solution or infinite solutions.

i.e. whenever there is no solution, we have A singular, i.e. rank of matrix will be definitely less than the number of equations/variables.

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
