Oscar's T-shirt Shop charges a design fee of $25 plus $15 per shirt for each new order. If Oscar charges the cost per shirt to $20, which of the following representations would accurately describe the situation? I. The difference between the rate of change for the new cost structure and rate of change for the old cost structure is $5 per shirt. II. The equation y=25x+20 represents the relationship between the total cost of the order, y, and the number of shirts, x, in the new cost structure. III.

step-by-step explanation:

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.
