1. En una empresa un analista obtiene la ecuación que describe la ganancia dada en MXN en base a la cantidad de piezas fabricadas ( x ): Ganancia \( =-x^{2}+800 x-10000 \) a) ¿De cuánto seria la ganancia si la empresa fabrica 100 piezas?

Look at the replacement set below. \[ \{0,4,5,13\} \] Which number from the replacement set is \( a^{\text {don }} \) solution of the inequality \( 8 \geq 5+x \) ? \( \begin{array}{llll}\text { A. } 0 & \text { B. } 4 & \text { C. } 5 & \text { D. } 13\end{array} \)

The measure of an angle is eight times the measure of its complementary angle. What is the measure of each angle?

10. Jika \( g(x)=x+3 \) dan \( (f \circ g)(x)=x^{2}-4 \), maka \( f(x) \) adalah \( \begin{array}{l}\text { A. } \\ \text { B. } x^{2}-1 \\ \text { C. } x^{2}-6 x-5 \\ \text { D. } x^{2}-6 x+5 \\ \text { E. } x^{2}+6 x+5\end{array} \)

11. Эгерде \( \left(7^{x}+7^{x}\right)^{3}=56 \) болсо, анда \( x= \) ? А) 1 Б) \( \frac{2}{3} \) В) \( \frac{1}{3} \) Г) \( \frac{1}{6} \) Д) \( \frac{1}{9} \)

Which expressions are equivalent to \( \frac{3}{5} x+3 \) ? Select all that apply. \( \begin{array}{ll}\text { QA. } 2+\frac{2}{5} x+1 & \text { ロB. } 2+\frac{x}{5}+1 \\ \square \text { C. } \frac{4}{5} x-\frac{1}{5} x+3 & \text { ロD. } \frac{2}{5} x+3 \frac{3}{5} x-1 \\ \text { पE. } 2+\frac{3}{5} x+1 & \text { ロF. } \frac{2}{5} x+3 \frac{1}{5} x\end{array} \)
