A boat goes 10 miles downstream in the same time it can go 3 miles upstream. The speed of the current is 2 miles per hour. Which equation could you use to find the speed of the boat in still water?

• $\frac{10}{2-x}=\frac{3}{2+x}$

• $\frac{10}{x-2}=\frac{3}{x+2}$

• $\frac{10}{x+2}=\frac{3}{x-2}$

• $\frac{10}{2+x}=\frac{3}{2-x}$

What are the asymptotes?

• x = -3        y = 1  
• x = 3         y = 1
• x = -3        y = -1
• x = 3         y = -1

Simplify.

• $\frac{\left(m+6\right)}{\left(m-3\right)}$

• $\frac{7}{\left(m-3\right)}$

• $7\left(m+6\right)$

• $\left(m-3\right)$
