Graph the solution to the following system of inequalities. \[ \begin{array}{l}y<3 x-5 \\ y \geq-2 x-7\end{array} \]

Simplify the expression to a + bi form: \[ (7-i)-(-5+6 i) \]

\( \operatorname{Lim}_{h \rightarrow 0} \frac{f(x+h)-f(x)}{h} \) de derivada por definición: \( f(x)=2 x-4 \) \( \operatorname{Lim}_{h \rightarrow 0} \frac{f(x+h)-f(x)}{h} \) \( h=\Delta x \) \( f(x)=2 x^{2} \)
