Answer:
See Below.
Step-by-step explanation:
We are given that:

By vertical angles:

Hence, by substitution:

Then by Angle-Angle Similarity:

Answer:
t2=15
t3=28
t4=41
first term (a)=2
common difference (d)=13
General terms tn=a+(n-1)d
Answer:
12. (4, 7)
13. (5, -1)
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex (h, k).
The answer is B, I attached a picture of the steps.
