Answer:
The answer is 5
Step-by-step explanation:
A is a 9 × 7 matrix
They have given that matrix A is two-dimensional null space
null(A) = 2
The matrix A has 9 rows and 7 columns
By rank nullity theorem
n = null(A) + rank(A)
n = number of columns in A
rank(A) = n - null(A)
= 7 - 2
rank(A) = 5
Therefore the rank of the matrix A is 5
