harry reads equal numbers of pages of a book every week. the graph shows the number of pages of the book left to read, y, after x weeks: (graph at the bottom)
which equation best models the relationship between x and y?
y = β5x + 55
y = β55x + 385
y = β5x + 275
y = β55x + 275
what is the initial value of the function represented by this graph?
a coordinate grid is shown with x- and y-axes labeled from 0 to 7 at increments of 1. a straight line joins the ordered pair 0, 5 with the ordered pair 7, 7. (graph at the bottom)

Given: ae β
ce ; de β
be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that β³aeb β
β³ced, we can show that β³ β
β³ceb by. so, β cad β
β by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
