The table below shows the high temperature, in degrees Fahrenheit, each day in Fairbanks, Alaska, during a week in January. The following Sunday, Erin recorded the high temperature and then calculated the mean high temperature, which she found was -1.5°F. What was the temperature on Sunday?

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.

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
