Question 1066439: A linear function models the height of a burning candle. Candle A comes out of the mold at 220 mm and is expected to be at 196 mm after 4 hours of burning. The model for candle B is h=290 - 5t, where h is the height in millimeters and t is the time in hours. What are the initial values for each candle?

You can put this solution on YOUR website!
h=196 and t=4 hours
196=220-xt, so -24=-xt
24=xt
24=4x
x=6
h=220-6t. units in mm
-------------
For B, 290-5(4)=290-20=270 mm, initial value of height.
