Hexagon defghi is translated 8 units down and 3 units to the right. if the coordinates of the pre-image of point f are
(–9, 2), what are the coordinates of f'?

The coordinates of F' is (-9 + 3, 2 - 8) = (-6, -6)

If gravity is one third on mars then weight also one third on mars

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
