Cooper just lit a new candle and then let it burn all the way down to nothing. The length of the candle remaining unburned, in inches, can be modeled by the function
L(t)=15−1.5t, L(t)=15-1.5t,
L(t)=15−1.5t, where
tt
t represents the number of hours since the candle was lit. What is the
xx
x-intercept of the function and what is its interpretation in the context of the problem?

The
xx
x-intercept of the function is which represents
