Struggling to Understand One-to-One and Onto in terms of Rank, Nullity ...
As in, what does it really mean to be one-to-one and onto in terms of Rank, Nullity, Null Space, Range, and the Dimension Theorem? I'm struggling to understand how these are all integrated together with the concepts of one-to-one and onto transformations. Hopefully someone can break these down into a simple explanation for better understanding.

Nullity theorem
The nullity theorem is a mathematical theorem about the inverse of a partitioned matrix, which states that the nullity of a block in a matrix equals the The nullity theorem states that the nullity of any submatrix equals the nullity of the complementary submatrix of the inverse.

Nullity (graph theory)
If the graph has n vertices and m edges, then: In the matrix theory of graphs, the nullity of the graph is the nullity of the adjacency matrix A of the In the matroid theory the nullity of the graph is the nullity of the oriented incidence matrix M associated with the graph. wikipedia.org

Nullity of a linear transformation $T$ > T is a projection onto the vector $v = (1, 2, 2)$ given by $$T(x,y,z) = \frac{x+2y+2z}{9} \cdot (1, 2, 2)$$ Use the given information to find the nullity of $T$. I know the nu...
And so the nullity is $2$. Implicitly, I'm thinking of the rank-nullity theorem.

Show that $nullity(B)\leq nullity(AB)$ Let A be an $m\times k$ matrix; Let B be an $k\times n$ matrix. a) Show that: $nullity(B)\leq nullity(AB)$ We had this in our previous midterms and even after viewing the offic...
What is proved there is that $\operatorname{null}(B)\subset\operatorname{null}(AB)$. It follows from this that $\dim\operatorname{null}(B)\leqslant\dim\operatorname{null}(AB)$.

Rank–nullity theorem
The rank–nullity theorem is a theorem in linear algebra, which asserts: the number of columns of a matrix is the sum of the rank of and the nullity Therefore, the nullity of is . Since equals rank of , it follows that . This concludes our proof. wikipedia.org

Show that $J-A$ will have nullity at least $9$ Show that if $A$ is a symmetric $n\times n$ matrix with nullity at least $10$ then $J-A$ will have nullity at least $9$ where $J$ is the all $1$ matrix of order $n\times ...
By rank-nullity theorem $$ \mathrm{rank}(A) = n - \mathrm{nul}(A) \le n-10. $$ Then, since $\mathrm{rank}(A+B) \le \mathrm{rank}(A) + \mathrm{rank}(B)$ , $$ \mathrm{rank}(J-A) \le \mathrm{rank}(J) + \mathrm{rank}(-A) \le 1 + n-10 = n-9. $$ Using rank-nullity theorem again we get $$ \mathrm{nul}(J-A) =
