Translate the following inference to logic notation: For all x, if x_8 were an artist, then x_8 is rich. For all x, if x_8 were rich, then x_8 is an artist. For all x, if x_8 were rich, then x_8 is an artist. Therefore if Sarah were rich, then Sarah is an artist.
forall x: P(x) -> Q(x). forall x: Q(x) -> P(x). forall x: Q(x) -> P(x). Therefore Q(a) -> P(a).
