Use the Rational Zero Theorem to list all possible rational zeros for the given function. \( f(x)=x^{4}+5 x^{3}-5 x^{2}+5 x-12 \)

Marco and Drew stacked boxes on a shelf. Marco lifted 9 boxes of equal weight. Drew lifted 14 boxes, but Drew's boxes of equal weight, but Drew's boxes each weighed 8 lb less than Nathan's boxes. Together, they lifted a total of 233 pounds. What was the weight of one of Marco's boxes?

9) Fred has 147 orange balloons and 44 black balloons. Fred has 21 times more orange balloons than Tom. How many orange balloons does Tom have?

Part 1 of 7 Determine the graph's end behavior. Find the \( x \)-intercepts and \( y \)-intercept. Determine whether the graph has symmetry. Determine the graph of the function. \( f(x)=x^{3}+3 x^{2}-x-3 \)

(a) \( 15^{\circ} \) If the straight line \( y=k x+1 \) is parallel to the straight line \( 2 y-x=5 \), then \( k= \) \( \begin{array}{llll}\text { (a) } 1 & \text { (b) } \frac{1}{2} & \text { (c) } 2 & \text { (d) }-2\end{array} \)
