Acandle that is 12 inches tall is burning at a rate of 0.25 inches per hour. the equation, y = - 0.25x + 12 describes the height, y, of the candle after x hours. what do the rate of change and y-intercept of this function represent?

the furthest the dog can be is 508 meters away from the house, and the closest he can be is 492 meters away from the house.

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
