Answer:
Translation and then reflection
Explanation:
First traslation of triangle ABC of 10 units to the right (+10,0)
A: (-5, 4) -> (+10,0) = A'': (5, 4)
B: (-6, 2) -> (+10,0) = B'': (4, 2)
C: (-4, 2) -> (+10,0) = C'': (6, 2)
Second a reflection across the x-axys.
A'': (5, 4) -> A': (5, -4)
B'': (4, 2) -> B': (4, -2)
C'': (6, 2) -> C': (6, -2)
