Answer:
False
Explanation:
If the row echelon form of the augmented matrix for a linear system has a row of zeros, then the there must not have infinitely many solution,
we can prove this with an example. Suppose we have an augmented matrix A for linear system with a row of zeros,
1 0 0 1
A= 0 1 0 -2
0 0 1 - 1
0 0 0 0
we get
x1=1
x2=-2
x3=-1
so, system has an unique solution.
we can take inference that the given statement is wrong
A. Air expands, becomes less dense and rises when the temperature is high due to the increased kinetic energy. This causes the air molecules to move around much more so they are further apart.
