14. AW║DZ
Step-by-step explanation:
11. If alternate interior angles are congruent, the lines the transversal crosses are parallel.
12. The sum ∠5+∠6 is an alternate interior angle with ∠10. The reasoning of problem 11 applies.
13. If same-side interior angles are suppplementary, the lines the transversal crosses are parallel.
14. Lines perpendicular to the same line are parallel.
if this is an actual question could you give the whole thing?

Determine f(3)
f(3) implies that x = 3.
We make use of

Because x >1 (i.e. 3 > 1)
Substitute 3 for x in f(x) =-3x + 1
