The cost of producing hard drives has three parts: cost of materials, cost of labor, and cost of equipment. to produce x hard drives, the cost of materials is 30x dollars and the cost of labor is 10x cents. the cost of equipment is a one-time, fixed amount of $10,000. which equation could represent the cost function for making x hard drives? answer choices f(x)=10,030.1x f(x)=10,000x+40 f(x)=30.1x+10,000 f(x)=40x−10,000

what i would say the best answer is a. 40.5

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.
