If we identify the points as follows, what are the inputs to the slope formula? \[ \begin{array}{r}(-1,-2) \text { and }(3,0) \\ x_{1} y_{1} \\ m=\frac{0--2}{3-[?]}\end{array} \] A. 0 C. -1

\( \frac{\frac{8}{5 x}-\frac{1}{x}}{\frac{4}{5}+\frac{3}{x}} \) \( \frac{\frac{8}{5 x}-\frac{1}{x}}{\frac{4}{5}+\frac{3}{x}}=\square( \) Simplify your answer. \( ) \)

Simplify. \( \frac{\frac{3}{x+5}}{x-5}-\frac{3}{x^{2}-25} \) \( \frac{\frac{3}{x+5}}{\frac{3}{x-5}-\frac{3}{x^{2}-25}}=\square \) (Use integers or fractions for any numbers in the expression.)

Considera la igualdad \( \mathrm{P}=\frac{\mathrm{n}-1}{\mathrm{n}+1} \), con n un número entero. ¿Para cuántos valores distintos de n se cumple que P es un número entero?

Perform the indicated operation. \( \frac{8}{x^{2}-2 x-35}+\frac{7}{x-7} \) \( \frac{8}{x^{2}-2 x-35}+\frac{7}{x-7}=\square( \) Simplify your answer. \( ) \)

Reste \( 2 x^{2}-7 x-1 \) de la suma de \( x^{2}+9 x-4 \) y \( -5 x^{2}-7 x+10 \)
