c) \( 2^{3} \cdot(-2)^{5} \cdot\left(3^{4}\right)^{2} \) \( (-6)^{4} \) Expresa el resultado como productos y cocientes de potencras del exponente pasitivo

Solve. \( 14 x^{2}-45 x>14 \) What is the solution? Select the correct choice below and, if necessary, fill in any answer boxes within your choice. (Simplify your answer.) A. \( \quad<x< \) B. \( x<\square \) or \( x> \) C. \( x=\square \) D. All real numbers satisfy the inequality. E. No real numbers satisfy the inequality.

The function \( f \) is defined by \( f(x)=-\sqrt{x} \). Write down the expression for \( h(x) \).

\( \left.\begin{array}{l}\text { Solve the system of equations }-6 x-5 y=-8 \text { and } 3 x+2 y=2 \text { by } \\ \text { combining the equations. } \\ \qquad \begin{array}{rl}(-6 x-5 y=-8) \\ (3 x+2 y=2)\end{array} \\ -6 x-5 y=-8 \\ 3 x+2 y=2\end{array}\right) \)

\( ( 6,4 ) \quad \left\{ \begin{array} { l } { y = \frac { 3 } { 2 } x - 5 } \\ { y = x - 10 } \end{array} \right. \)

\( (4 \mathrm{p}) \) a) \( 5 x^{2}-3 x=0 \) \( (4 \mathrm{p}) \) b) \( 6 x^{2}+12 x=0 \) \( (4 \mathrm{p}) \) c) \( 8 x^{2}-24=0 \) \( (4 \mathrm{p}) \) d) \( -4 x^{2}+100=0 \) (4p) e) \( x^{2}+8 x-33=0 \) \( (4 p) \) f) \( x^{2}+9 x+20=0 \)
