Find the maximum value of the function \( z=5 x+6 y \) subject to the following constraints. \( \left\{\begin{array}{c}y \geq 0 \\ x \geq 2 \\ y \leq 5 \\ 5 x+2 y \leq 50\end{array}\right. \) Note that the ALEKS graphing calculator can be used to make computations easier. \( z=\square \)

\( \int \frac { 3 x ^ { 2 } - 6 x - 1 } { ( x + 1 ) ( x - 1 ) ( x ^ { 2 } + 1 ) } d x \)

ntre numeros de \( \frac{-\frac{6}{5} \cdot \frac{3}{4}}{\frac{9}{8}} \)

\( \mid \leftarrow \) Simplify the fraction by reducing it to its lowest terms. \( \frac{15}{20}=\square \) (Simplify your answer.)

b) \( \frac{-3 x^{2}}{}=3 x \)
