HELP ASAP 1.Bill wanted to use the Distributive Property for the following expression. Distinguish whether he made an error in his work. If he did, correct his error and simplify the expression using the Distributive Property and combine like terms.
-(2a + 6b – 3c) + 4(3b + 7c)
-2a + 6b – 3c + 12b + 7c
-2a + 6b + 12b – 3c + 7c
-2a + 18b + 4c

2.Construct 5 equivalent equations for the equation -3x + 1 = 2. Describe which value you multiplied by for each equivalent equation. Show all of your work to prove your answers are correct.

3.The number of players leaving the league can be calculated by starting with the quantity of four times a number less than 250 is equal to 160. Which equation represents this situation?

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.
