A 7-inch candle burned at the rate od 0.5 inch per hour. write a two variable linear equation that represents the height of the candle, h after x hours

h = 7 - 0.5x

Step-by-step explanation:

h = mx + b

The height of the candle decreases by 0.5 in/h, so

m = - 0.5

y = - 0.5x + b

When x = 0, h = 7.

7 = - 0.5*0 + b

7 = 0 + b

b = 7

h = - 0.5x + 7 or h = 7 - 0.5x

14 hours

Step-by-step explanation:

You basically divide 7 by. 5.
