Alex is tracking temperatures. Today the temperature was 0° Celsius, which is represented by the point (0, 0) . If the temperature yesterday was right in between today’s temperature and the temperature two days ago, what was the temperature yesterday?
(1 point)
Yesterday’s temperature was
° Celsius.
If the temperature two days ago was represented by the point (x, y), and the temperature yesterday was right in between today's temperature and the temperature two days ago, we can find the temperature yesterday by taking the average of the x-coordinates and the average of the y-coordinates.
Since today's temperature is represented by the point (0, 0) and the temperature two days ago is represented by the point (x, y), we have:
Average of x-coordinates: (0 + x) / 2 = (0 + x) / 2 = (x/2)
Average of y-coordinates: (0 + y) / 2 = (0 + y) / 2 = (y/2)
Since the temperature yesterday is right in between today's temperature (0, 0) and the temperature two days ago (x, y), the coordinates of the temperature yesterday would be ((x/2), (y/2)).
Therefore, the temperature yesterday would be (x/2) Celsius.
