Question

A candle is 17 in. tall after burning for 3 hours. After 5 hours it is 15 in. tall write a linear equation to model the relationship between height h of the candle and time T. predict how tall the candle will be after burning 8 hours.

Answer 1

any ideas?

Answer 2

Let x and y be the candles height and burn rate in inches per hour, respectively.
Solve the following equations for x and y.
{ x - 3 y = 17, x - 5 y = 15 } // Solve
x = 20, y = 1
20 - 8*1 = 12
