1. If the root of equation 5 (x-1) = 3A + X-11 of X is nonnegative, then the value range of a is () 2. Given the linear function y = (M + 2) x - (M + 3), y decreases with the increase of X, and the intersection of image and Y axis is above X axis, then the value range of real number m is () 3.

1. A is greater than or equal to 2. From the equation: 4x = 3a-6. Because x is a non negative number, 3a-6 is greater than or equal to 0
2. From the fact that y decreases with the increase of X, we know that M + 2 is less than 0, and the intersection of image and Y axis is above X axis. We know that when x = 0, y is greater than 0, that is -- (M + 3) is greater than 0
3. K = 36-y is obtained from 2x-24 = 0 and 3x-y-k = 0
4. When x = 0, y is less than or equal to 0, that is, M-1 is less than or equal to 0, and the solution m is less than or equal to 0
5. Take any number
6. From the inequality: x greater than m + n-2, less than m know M = 2, M + n-2 = - 1: M = 2, n = - 1. Then (M + n) * 2008 = 2008
