The cost for an upcoming field trip is $15 per student. The cost of the field trip C, in dollars, is a function of the number of students, x . a) Write a function rule to represent the situation.

b) What does C ( 4) = 60 mean in the situation?

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

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.
