A hot tub is draining, and the water level is decreasing at a constant rate. After 9.3 minutes, the tub contains 401.92 gallons.
After 15.8 minutes, the tub contains 235. 52 gallons. 1. Calculate the y-intercept by using the calculated slope and the ordered pair that includes 15.8 minutes.
2. What does the y-intercept represent in this situation
3. Find the slope by substituting the coordinate values of the order formula.
4. What does the slope represent in this situation?
Let x be the no. of seconds it takes for the balloons to be at the same height. 7+3x = 12+2x Deduct both sides by 2x. 7+x = 12 Deduct both sides by 7. x = 5 Ans: It will take 5 seconds for the balloons to be at the same height.
