Find the x if the sum of three numbers is 180 and the numbers are 45,68,(3x+16)

Which function is represented by the graph

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 f(x)=x+7 and g(x)=1/x what is (fog)(x)
