. Anna bought 8 tetras and 2 rainbow fish for her aquarium. The rainbow fish cost $6 more than the tetras. She paid a total of $37. Which of the following are true? Select all that apply. ◻ A. The cost of 4 tetras is the same as the cost of a rainbow fish.
◻ B. One rainbow fish plus 5 tetras cost $21.
◻ C. An equation to find the cost r, in dollars, of a rainbow fish is 8r + 2(r + 6) = 37
◻ D. Reducing the number of rainbow fish by 1 would result in a total cost of $28.50.
◻ E. An equation to find the cost t, in dollars, of a tetra t is 8t + 2t + 6 = 37.

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.
