A linear function models the height of a burning candle. Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning. The model for Candle B is h=210−5t, where h is the height in millimeters and t is the time in hours. What are the initial values for each candle? What do the initial values for each candle tell you?

Given:

Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning.

The model for Candle B is

where, h is the height in millimeters and t is the time in hours.

To find:

The initial values for each candle and its interpretation.

Solution:

Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning.

So, initial value of candle A = 211 mm

The model for Candle B is

Putting t=0, we get

So, initial value of candle B = 210 mm

Initial values for each candle tell you about the height of the candles before they start burning.

Initial value of candle A is greater than B, so the height of candle A is greater than B before they start burning.

Therefore, the initial value of candle A is 211 mm and initial value of candle B is 210 mm.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
