which sequence of transformations will map figure k onto figure k′?

reflection across x = 4, 180° rotation about the origin, and a translation of (x + 8, y)
reflection across x = 4, 180° rotation about the origin, and a translation of (x − 8, y)
reflection across y = 4, 180° rotation about the origin, and a translation of (x + 8, y)
reflection across y = 4, 180° rotation about the origin, and a translation of (x − 8, y)
