Which equation can be used to find the number of wolves in the state on january 1?
a zoologist is recording the loss of wolves in her state. she notes the number of wolves, w, in the state on january 1. one year later, there were 84 wolves in the state, which is 23 fewer wolves than were in the state a year earlier. what is the number of wolves in the state on january 1?
w − 23 = 84
23 − w = 84
w + 23 = 84
w− 84 = −23
visitor attendance at the nature center in december is one-quarter the attendance in september. in december, 94 people visit the nature center.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

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.
