The average distance from Mercury to the sun is approximately 5.79 × 10 7 km. If one kilometer is equal to about 6.68 × 10 –9 astronomical units, about how many astronomical units is the average distance from Mercury to the sun? Write your answer in scientific notation.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

i think its a.

hope this
