Answer:
5°C
Step-by-step explanation:
We need to add 12 onto the -7:
-7 + 12 = 5
Answer: A. 3 ways: k, DE, ED (both DE and ED have line markers over top)
To name a line, we just need two points on the line. We list them in any order because the line extends forever in both directions. Contrast this with a ray where order does matter. The little k is another way to name a line, potentially simplifying things.
Choice B is close, but it mentions ray DE instead of line DE. Choice C is missing line ED. Choice D is a similar story as choice B. These facts allow us to rule out B through D.
