Select all the correct answers. Annie transforms the graph of y = 2x into the graph of y = 2x - 4. Which statements correctly describe this transformation?
It is the graph of y = 2x translated 4 units to the right.
It is the graph of y = 2x translated 4 units downward,
It is the graph of y = 2x translated 4 units upward.
It is the graph of y = 2x translated 2 units to the right.
It is the graph of y = 2x stretched vertically 2 units upward.

Recall that f(x) − k is a vertical translation that translates f(x) down k units. And, a vertical translation also translates a function horizontally, and vice versa. So, y = 2x − 4 translates the function y = 2x down 4 units. But 2x − 4 is also equal to 2(x − 2), so y = 2x − 4 also describes a translation to the right by 2 units.

Plato answer

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.
