y = -0.1x+1 0.5 = -0.1x+1 -0.5 = -0.1x x = 5 It takes 5 seconds for the download to be 50% complete.
Given : y = -0.1x + 1 where, y = percentage, x = time in seconds Now, substituting the values from the question into the equation, we get, 50% = -0**.**1x +1 ** . 50 - 1 = -0 . 1x - . 50 = -0.1x - . 50 / (-0 .**1) = x 5 = x x = 5 So, the time taken to download 50% of the song is 5 seconds
