BC would equal the same as EF, they are similar. All you would have to do is figure out the pre image (BC) of EF.
Answer:
Step-by-step explanation:
A(2,2) B(-2,1) and C( 3,-3)
reflection over the the y-axis of (x, y) becomes ( -x, y)
A'( -2,2), B'( 2, 1) and C'( -3,-3)
The pattern starts at 2/14 and increases by 1/14 each node, so the next fraction is 6/14 which simplifies into 3/7
240,000 (0.03) is the answer
