An art store sells fabric. the relationship between the area and the cost of the fabric is shown in the following graph.

which statements about the graph are true? choose all answers apply:

a.) the point (0, 0) shows that the cost is $0 for 0m of fabric.

b.) the point (4, 24) shows that the cost is $24 for 4 m of fabric.

c.) none of the above

me with this question and

if the answer for b is 4 square meters of fabric then both a and b will be the right answer. If you look at the graph, it starts at the points (0,0) which proves that it costs $0 for 0 square foot of fabric. Sames goes for choice b.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
