(1) The number of machines transferred from warehouse A to county B is (12-x); (2) the number of machines transferred from warehouse B to county a is (10-x); (3) the number of machines transferred from warehouse B to county B is (x-4); (4) the total freight of these machines is: X × 40 + (12-x) × 80 + (10-x) × 30 + (x-4) × 50 = 1060-20x (yuan); (5) when x is 10, the total freight is the least

A company has 12 and 6 agricultural vehicles in the two warehouses of a and B. now it needs to transfer 10 vehicles to a county and 8 vehicles to B county. It is known that one agricultural vehicle is transferred from a warehouse
The freight to a county and B county is 40 yuan and 80 yuan respectively; the freight to a county and B county from B warehouse is 30 yuan and 50 yuan respectively?

Set a to ax, total freight: y yuan
The results show that y = 40x ＋ (12-x) × 80 ＋ (10-x) × 30 ＋ (8 - (12-x) > × 50
And Y ≥ 900
Conclusion: X ≥ 8
And ∵ x ≤ 10
There are three schemes for x = 8, 9 and 10
According to the above formula, 1260-20x = y is obtained
The minimum value of Y is 1260-20 × 10 = 1060 yuan
Minimum: 1060 yuan

There are 12 farm vehicles and 6 farm vehicles in warehouse A and B respectively. Now 10 farm vehicles need to be transferred to county a and 8 farm vehicles need to be transferred to county B. It is known that the freight of transporting one farm vehicle from warehouse A to county a and county B is 40 yuan and 80 yuan respectively; the freight of transporting one farm vehicle from warehouse B to county a and county B is 30 yuan and 50 yuan respectively. (1) suppose x farm vehicles are transferred from warehouse B to county a, find the function of total freight y with respect to X (2) if the total freight is required to be no more than 900 yuan, how many kinds of transportation schemes are available; (3) how much is the minimum freight for the lowest transportation scheme?

(1) If warehouse B transfers x agricultural vehicles (x ≤ 6) to county a, warehouse B transfers 6-x agricultural vehicles to county B, and county a needs 10 vehicles. Therefore, a transfers 10-x agricultural vehicles to county a, and county a transfers x + 2 agricultural vehicles to county B. according to the freight of each transfer mode, the equation can be listed as follows: y = 40 (10-x) + 80 (x + 2) + 30x + 50 (

There are 12 agricultural vehicles and 6 agricultural vehicles in the two warehouses,
At present, 10 vehicles need to be transferred to county a and 8 vehicles need to be transferred to county B. It is known that one vehicle is transferred from county a to county ab
1. Write out the functional relationship of total freight y with respect to X (let a county use x cars)
2. If the total freight is required to be no more than 900 yuan, there are several transportation plans
3. Find out the lowest transportation scheme. How much is the lowest freight
