Given that the image of inverse scale function y = K / X (K ≠ o) intersects with the image of primary function y = KX + m (K ≠ 0) at a (2,1), find B

Taking a (2,1) with two equations, we can find k = 2, M = - 3. Then we can combine two equations, that is, 2 x = 2x-3. We can find a (2,1). B (- 1 / 2, - 4)

2. A mathematical problem of quadratic function in junior high school (speed) China is one of the countries with serious water shortage in the world. In order to enhance the residents' awareness of water saving, a municipal water supply company charges for the residents' water consumption by taking the household as the unit. That is to say, users with water consumption less than 10 tons (including 10 tons) per month will be charged a yuan per ton; users with water consumption more than 10 tons per month will still be charged a yuan per ton, and users with water consumption more than 10 tons will be charged a yuan per ton, The charge is B yuan per ton (b > A). If a household uses X tons of water per month, it should charge y yuan. The functional relationship between Y and X is shown in the figure 1. For the value of a, how much should a household charge for using 8 tons of water last month? 2.
