The correct Answer is:
To solve the problem regarding the statements about the system of linear equations represented by \( AX = B \), we will analyze each statement step by step. ### Step-by-Step Solution: 1. **Understanding the Given Statements**: - **Statement 1**: If \( |A| = 0 \) and \( (\text{adj} A)B \neq 0 \), then the system is consistent with infinitely many solutions. - **Statement 2**: \( A \cdot (\text{adj} A) = |A|I \). 2. **Analyzing Statement 1**: - If \( |A| = 0 \), it indicates that the matrix \( A \) is singular, meaning it does not have an inverse. - For a system of equations to be consistent, it must have at least one solution. However, if \( |A| = 0 \) and \( (\text{adj} A)B \neq 0 \), it implies that the system does not have a solution. Therefore, Statement 1 is **false**. 3. **Analyzing Statement 2**: - The adjoint of a matrix \( A \), denoted as \( \text{adj} A \), has a property that states \( A \cdot (\text{adj} A) = |A|I \). - This is a standard result in linear algebra and holds true for any square matrix \( A \). - Therefore, Statement 2 is **true**. 4. **Conclusion**: - Since Statement 1 is false and Statement 2 is true, the correct conclusion is that the first statement is incorrect while the second statement is correct. ### Final Answer: - Statement 1: False - Statement 2: True
