Amber, Bill, Clarence, and Diana each made a statement about the relation {(1, –2), (1, 2), (3, –4), (3, 4), (5, –6), (5, 6), (100, –101), (100, 101)}. Which student's statement is completely true? Amber said "It is two functions: y = (x + 1) and y = –(x + 1) for all x in the domain."

Diana said "It is not a function because functions must map domain values into single range values."

Clarence said "It is not a function because there are not enough values in the domain."

Bill said "It is a function: y = ± (x + 1) for all x in the domain."

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

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
