What is the additive inverse of the polynomial? -7y^2+x^2y-3xy-7x^2

Additive inverse is  (7y² - x²y + 3xy + 7x²).

Step-by-step explanation:

Let the additive inverse of the given polynomial be Y.

Therefore as per definition of additive inverse of any polynomial the addition of a polynomial and additive inverse of any polynomial is always zero.

So Polynomial + additive inverse polynomial = 0

(-7y² + x²y - 3xy - 7x²) + Y = 0

Y = -(-7y² + x²y - 3xy - 7x²) = (7y² - x²y + 3xy + 7x²)

So the additive inverse of the polynomial will be (7y² - x²y + 3xy + 7x²).

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.
