(x-5)/(x-4)
Answer: 28 km
Step-by-step explanation: For the first 25 minutes, he drove 60 km/h. Since there is 60 minutes in an hour, we know that he drove 25 km. The rest of the journey is 15 minutes. 15 minutes is 1/4 of an hour, so get 1/4 of 12 km/h. This would be 3 km. Add 25 km and 3 km. The distance between the 2 malls is 28 km.
Answer:
Step-by-step explanation:
If the speed is constant for 5 machines and produces x amount of toys we know that rate is defined as a constant per time:
Here the machines are constant and the rate is x toys per hour:
If 5 machines make x per hour:
Rate is x/1 hour
The the ratio of 8/5 is 1.6. Therefore for 8 machines the rate is 1.6 times more per hour than for5 machines. Therefore we can write an expression as:
Rate for 5 machines is x and for 8 machines is y:
Answer: (below)
Step-by-step explanation:
y = 2x + 1
slope = 2
y-int = (0, 1)
y = 3x - 1
slope = 3
y-int = (0, -1)
y = 4x
slope = 4
y-int = (0, 0)
y = -3x - 1
slope = -3
y-int = (0, -1)
y = -x - 4
slope = -1
y-int = (0, -4)
y = (2/5)x - 1
slope = 2/5
y-int = (0, -1)
