Fully simplify the expression below and write your ver as a single fraction, \[ \frac{10 x^{2}-40}{5 x^{3}-35 x^{2}} \cdot \frac{x^{4}-49 x^{2}}{x^{2}+9 x+14} \]

5. Fourth term of arith sequence is 11 , and the \( 6^{2} \) term is 17 . Find the second term. \( a_{4}=11 \quad a_{6}=17 \quad a_{1}+(n-1) \)

10. \( \begin{array}{l}x+y=3 \\ 2 x+4 y=8\end{array} \)

Determine whether the following equation defines \( y \) as a function of \( x \). \[ x^{2}+y=49 \] Does the equation \( x^{2}+y=49 \) define \( y \) as a function of \( x \) ? Yes No
