If the fuel tank of a car is filled with 45 liters of gasoline at a time, it is feasible to drive y km. Suppose that the car consumes x liters of fuel every 100 km, then the analytic function of Y with respect to X is______ ．
∵ a car consumes x liters of fuel every 100 kilometers, 1 liter of gasoline can travel 100x kilometers, y = 45 × 100x = 4500X
There is 65 liters of fuel before driving, and 15 liters of fuel is consumed every 100 km. For safety, at least 5 liters should be stored in the fuel tank
To find the analytic expression and domain of function of Y with respect to X
When there is 20 liters of oil left in the tank, calculate the distance
Y = 65-15x / 100, and Y ≥ 5, i.e
65-15x/100≥5
x≤400
So y = 65-15x / 100, (0 ≤ x ≤ 400)
y=65-15x/100=20
x=300km
With 15 liters of gasoline in the fuel tank, can you reach the gas station with a distance of 100 km? The fuel consumption per kilometer is 7.5 liters
Brother, are you driving Optimus Prime? I'm kneeling down. I don't want to drive 75 liters of oil for 10 kilometers... 15 liters of oil. You can drive 80 to 100 kilometers for a 4.0 car
There is 100L gasoline in the gasoline tank of a car, and the car consumes 5L fuel every 50km. How many liters of fuel is left in the mailbox when the car runs for XKM? The answer of a student is: (100-5x) L. try to analyze whether the student's answer is correct. If not, please point out the reason for the error and write the correct answer
Consumption per kilometer 5 △ 50 = 0.1L
So 100-0.1 x liters left
