A cable company charges 150 to install equipment. Then there is a $50 charge each month. Is there a proportional relationship between time and the cost of the cell phone plan? Explain how you know.

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

If sin(x) = 0 and cos(x) = 1, what is tan(x)?
