2. Crate a racio lable for making lemonade with a lemon juice-to-water ratio of 1 : 3 . Show how much lernon Wulce would be neected if you use lo cups of water to make lemonade. Mow ia the walue of the ratio uned to create the table?

Given \( f(x)=-x+3 \), find \( f(3) \)

11. \( f(x)=-2(x-1)(x-8)(x-2) \)

a) \( \begin{aligned} {[1.6+3(\quad)]+4[-1+3(\quad)-0.7]=1.6 } & +3.3+4[-1-1.5-0.7] \\ & =1.6+3.3+4[\quad]=1.6+3.3-12.8=\end{aligned} \)

If you see an array with 1 row and 9 columns, what is the multiplication fac \( 1 \times 91 \times 9 \) \( 9 \times 19 \times 1 \) \( 9 \times 99 \times 9 \) \( 1 \times 81 \times 8 \)
