(4.) \( \frac{4-3 x}{(x+2)(x-1)} \geq 0 \)

13. Mitchell is comparing the cost of frozen yogurt at two different shops. He makes a graph relating the number of ounces of yogurt on the \( x \)-axis to the cost of the yogurt on the \( y \)-axis. The graph for each shop is a straight line and the lines intersect at \( (4,3.25) \). What can you conclude from this?

Factor. \[ 9 v^{2}-48 v+64 \]

For each expression below, rewrite the subtraction as addition opposite and combine the like terms. Verify that your simplific expression is equivalent to the original expression. a. \( 2 y-9 z^{2}-4 y \)

18. Matt and Ming are selling fruit for a school fundraiser. Customers can buy small boxes of oranges and large boxes of oranges. Matt sold 3 small boxes of oranges and 14 large boxes of oranges for a total of \( \$ 203 \). Ming sold 11 small boxes of oranges and 11 large boxes of oranges for a total of \( \$ 220 \). Find the cost each of one small box of oranges and one large box of oranges.

Vuelve a escribir la expresión en la forma \( k \cdot z^{n} \). Escribe el exponente como un entero, una fracción o un decimal exacto (no como número mixto). \( \frac{10 \sqrt[3]{z}}{2 z^{2}}=\square \)
