Answer:
(a) Theorem 9
Step-by-step explanation:
Any of the given theorems can be used to prove lines are parallel. We need to find the one that is applicable to the given geometry.
<h3>Analysis</h3>
The marked angles are between the parallel lines (interior) and on opposite sides of the transversal (alternate).
Theorem 9 applies to congruent alternate interior angles.
Answer:
ouuuuu that is a really good question
1. 1st transformation is translation the parent function
6 units to the right to get the function 
2. 2nd transformation is reflection the function
over the x-axis. This transformation gives you the function 
3. 3rd transformation is vertical stretch of the function
by a factor of 2 to get the function 
Only last two are present in options, then
answer: C and D.
