23. a candle is 10 in. tall after burning for 2 hours. after 3 hours, it is 8.5 in. tall. how tall will the candle be after 6 hours?

The candle be 4 inches tall after 6 hours.

Step-by-step explanation:

After burning for 2 hours, the length of a candle = 10 inches

After 3 hours the length of the candle = 8.5 inches

Therefore, the candle burn in 1 hour = 10 - 8.5 = 1.5 inches

In the question it is given that after 3 hours it is 8.5 inches tall and we have to calculate the length of the candle after 6 hours which means 3 more hours candle burn.

In 1 hour candle burn for = 1.5 inches

in 3 hours candle will burn = 1.5 × 3 = 4.5 inches

after 3 hours more of burning the length will be = 8.5 - 4.5 = 4.0 inches.

The candle be 4 inches tall after 6 hours.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
