There are 21 students in one class and 19 in another. the lab has 34 computers. how many students will need to share a computer when both classes are in the lab at the same time ?

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)=3x+1 and f^-1=x-1/3, then f^-1(7)=
