A police helicopter descends 128 feet to hover 468 feet above the ground. Let h
represent the original height of the
helicopter. Write and solve an equation to
represent this situation.

h - d = 477 meters

Where:  h = original height

           d  = amount the helicopter descended

The original height of the helicopter is given to be h

Step-by-step explanation:

it would be 6xy and -16xy.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
