The chosen topic is not meant for use with this type of problem.
However, if you simplify it, your answer is:
x^2 − 2x − 35
This is because simplifying the equation before solving it will lead you to the answer at a much faster rate. For example, in the given equation, the long way would be to distribute 2 to (x+3). Then, you transpose them and combine like terms. Until you get to x + 3 = 8. But if you simplify it first, you will see that it is straightforward. It will lead you to the answer right away which is x + 3 = 8. It saves you from the hassle of doing more algebra :)
I'm assuming you mean which one is written properly? It would be either 3 x 10^4 or 6 x 10^4.
Hope it helps!
Use the formula
y+2=-5/7(x+1)
solve and you will get the equation which is
f(x)=-5/7(x)-19/7
