Can someone please help me with question 3
Anastasy [175]

Answer:

8.55 inches tall

Step-by-step explanation:

equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.

Now plug in 4.6 for t you get:

h = -0.75t + 12

h = -0.75(4.6) + 12

h = -3.45 +12

h = 8.55 inches tall
