I think the answer be C? Sorry if it's wrong
If you flip over the x-axis A' would be (1, -1) (just change the sign on the x)
Then rotate 180 reverse the points to get A'' at (-1, 1)
8,000 kilograms = 8000000 grams
Just move the invisible decimal to the left until it is less than 10
19,000,000,000 is 1.9*10^13
Enjoy!!!
