Complete all of the following steps to for each problem below. Write C for combine (add) or D for difference (D)Write (+) if the sum will be positive or (-) if the sum will be negativeDetermine the final answer8 + -2 = -9 + -12 = -35 + 25 = -19 + 40 = 

+6

Step-by-step explanation:

We have to solve the following expression:

8 + (-2)

The + sign before the parenthesis means that the signal of the terms inside the parenthesis stay the same. So

8 + (-2) = 8 - 2 = +6

The answer is +6.

10.50 + taxes which added up to 11.50

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.
