If \( f(x)=x^{3}+x^{2}-44 x+96 \), which of the following is not a factor of \( f(x) \) ?

2. Tobi recruits twice as many students for the project as Erica. Six of the recruits are the same. Which equation describes these facts? (Use \( x \) for Tobi's unique number. Use \( y \) for Erica's unique number.) A \( x+6=2(y+6) \)

27) \( \begin{array}{l}2 y+x-4=0 \\ 2 y=-x+4\end{array} \)

Use the given \( n \)th term formula to compute the first five terms of the sequence. \( a_{1}=\square a_{n}=9 n^{2}-8 n \) \( a_{2}=\square \) \( a_{3}=\square \) \( a_{4}=\square \) \( a_{5}=\square \)

15. What is the value of \( x \) and \( y \) in a given two equal ordered pair below: \( \begin{array}{l}2 x+1,3 y+4)=(-4 x-2,5-2 y) \\ x=-1 / 2, y=1 / 5 \\ x=1 / 5, y=1 / 2 \\ x=1 \text { and } y=3 \\ x=-1,0 \text { and } y=5\end{array} \)

1. \( |x-5|=9 \)
