Answer:
a)The slope of A"D" is 3
The slope of B"C" is 3
b) The line segments A"D" and B"C" are congruent and parallel.
Step-by-step explanation:
The pre-image of the parallelogram, has slope of AD equal −3 and the slope of BC equal −3.
Since translation and reflection are rigid transformations, the preimage and the image are congruent.
This means that the lengths of the corresponding sides are equal.
Hence AD=A"D'' and B"C"=BC
However, since the image after a reflection in the y-axis is laterally inverted, the slope of A"D" will be negative of the slope of AD.
Similarly, the slope of B"C" will be negative of the slope of BC.
The slope of A"D" is 3
The slope of B"C" is 3
Since the two line segments have the same slope, they are parallel.

All the cups are in there correct spot and the labels are fine also.
(then someone had to come in dis room with BLUE CAPS AND REPLACE ALL OTHER THE CORRECTLY ORDERER PEN CAPS WITH BLUE PEN CAPS AND SWITCH THE GOSH DARN LABELS. THANKS ALOT, TIM) anyways... i say that the minimum numbers of pens you can test is about 4. probably....

You can answer this by setting up a proportion using the information given.
You can use a proportion because the distance around is a one dimensional measurement.
The answer is 4005.384 km longer.
Please see the attached pic for the work in solving the proportion.
