D is a function because there are no repeated x values
for example b is not a function because we have (0,-7) and (0,-9)

Answer:
3 - (-7)
= 3 + 7.
Step-by-step explanation:
A double negative is equivalent to a plus.
Tan(52°) = opposite/adjacent = x/35 ⇒
x = 35 * tan(52°) = 35 * 1.2799 ≈ 44.80
The anwser is 17 and 3. 17+3=20, and the difference is 14!
