Although one downvote does not make a controversy, I'll add some up-front clarification to the Q.

comment How to draw the graph of $y=(2x^2+13x+9)/(6x+3)$
Start by finding some points on the graph (you supply an $x$ value and compute $y$).

comment Analyze the nature and location of equilibrium points
I think it makes sense as an autonomous system of differential equations. Assuming that $p$ is a parameter means it is fixed, an equilibrium point would mean a point $(x,y)$ on the curve $g(x,y,p)=0$ where $\dot{x} = -yx + 2p = 0$.

comment About a technique used in the proof of Hahn-Banach Theorem
Perhaps a more important topic to explore is why the concept of "sublinear function" is important. You've already noted that a norm is a sublinear function, which gives us useful examples.

comment About a technique used in the proof of Hahn-Banach Theorem
The proof you describe seems to favor brevity over motivation. I think you are asking, how would someone come up with such a proof? Of course the definition of sublinear function requires that we deal with some inequality, so the only mystery is how the author came to choose this particular inequality as the cornerstone of the proof.

comment Determine the matrices $A$ and $B$ if $2A + 3B$ and $A + B^T $ is given
Plugging in your solution, $2A+3B$ gives $$\begin{bmatrix} 8 & 3 \\ 5 & 6 \end{bmatrix}$$ which is not quite what is called for.

comment Per person fuel consumption on a ship.
@Safronicus: Start by reading the problem to determine the "unknown" it asks you to find. Choose a variable to represent that unknown quantity, and then try to express the information given in the problem using algebra.

comment Are the "teaching" and "learning", and "education" tags appropriate here given that there's a ME.SE?
@RespawnedFluff: I'm going to retag that (on-hold) Q to "word-problem", but the OP's selection of tags ("i don't know what any of those mean, i just put them there so I could submit the question") is almost too priceless to tamper with.
