I am taking a Linear Algebra class to finish up my master's degree in math curriculum and instruction. I have been doing okay until these questions. I need some help.
True/False
1. If Ax=b has infinitely many solutions, then so does Ax=0.
2. If Ax=b is inconsistent, then Ax=0 has only the trivial solution.
3. The fewest number of hyperplanes in R^4 that can intersect in a single pt is 4.
4. If W is any plane in R^3, there is a linear system in three unknowns whose solution set is that plane.
5. If Ax=b is consistent, then every vector in the solution set is orthogonal to every row vector of A.
I really hope that someone can help me!
