Chris is comparing two sales positions that he has been offered. The first pays a weekly salary of $375 plus a 20% commission. The second pays a weekly salary of$325 plus a 25% commission. How much must he make in sales per week for the two jobs to pay the same?

Write the equation of each line in the given form. The line through (-4, 2) with slope $\frac { 3 } { 4 }$ in point-slope form.

How can you recognize the slope-intercept form of an equation?

A traffic engineer calculates the speed of vehicles as they pass a traffic light. While the light is green, a taxi passes at a constant speed. After 2 s the taxi is 132 ft past the light. After 5 s it is 330 ft past the light. Use the fact that 22 ft/s = 15 mi/h to find the taxi's speed in miles per hour.

Are the Reflexive, Symmetric, and Transitive Properties true for parallel lines? Explain why or why not. Reflexive: $\ell \| \ell$. Symmetric: If $\ell \| m$, then $m \| \ell$, then $m \| \ell$. Transitive: If $\ell \| m$ and $m \| n$, then $\ell \| n$.

Use the theorems and given information to show that $n \| p$.

$$\angle 2 \cong \angle 7$$
