Answer:
(-3, 13)
Step-by-step explanation:
The transformation that moves a point 4 left and 8 up is ...
  (x, y) ⇒ (x -4, y +8)
The transformation that reflects a point across the y-axis is ...
  (x, y) ⇒ (-x, y)
Applied after the translation, the transformation of ∆ABC becomes ...
  (x, y) ⇒ (-(x -4), y +8) = (4 -x, y +8)
Then point A gets moved to ...
  A(7, 5) ⇒ A'(4 -7, 5 +8) = (-3, 13)
