A. a reflection in the y-axis, followed by a translation 6 units up
B. a reflection in the x-axis, followed by a translation 2 units left
C. a reflection in the x-axis, followed by a counterclockwise rotation of 180 about the origin
D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin

Answer:

The answer i choose is D

Explanation:

i choose D because 1.) i you worked out answer A than it would be sideways and wouldn't even fit on the board. 2.) if you worked out problem B than you will notice that the figure will end up sideways again. 3.) if you did answer C than you don't even end up in the right quadrant of the board

so you are left with D.) a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin

Answer:

D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin

Explanation:

Well, the first obvious step is to reflect it across the y-axis. Now, for the next step, since we do not have a 90°-clockwise rotation option, we have to go with something similar to that, which would be a 270°-counterclockwise rotation. If you think about it, since 3 × 90 is 270, and rotating this figure 90° clockwise [one rotation] would go from Quadrant III to Quadrant II, going the other way around [270°counterclockwise (three rotations)] will also go from Quadrant III to Quadrant II [to Quadrant IIII to Quadrant I to Quadrant II].

I am delighted to assist you anytime my friend.
