Two lines, C and D, are represented by the equations given below: Line C: y = x + 14

Line D: y = 3x + 2

Which of the following shows the solution to the system of equations and explains why? (5 points)

a

(6, 20), because both lines pass through this point

b

(6, 20), because the point does not lie on any axis

c

(3, 11), because one of the lines passes through this point

d

(3, 11), because the point lies between the two axes

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
