The known set a = {XLX & # 178; - 2x-3 ≤ 0, X ∈ r}, B = {XLX & # 178; - 2mx + M & # 178; - 4 ≤ 0, X ∈ R, m ∈ r}
① If a ∩ B = [0,3], find the value of real number M;


In this paper, we will be the authors of the following (x \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\3], then m-2 = 0, M + 2 ≥ 3



The image of a certain function passes through the point (0,2), and the value of function y decreases with the increase of independent variable x. please write a function relation that meets the above conditions


y=-2x+4



8 [x-6.2] = 41.6


8[x-6.2]=41.6
8x-49.6=41.6
8x=91.2
x=11.4



If we know that the focus of an ellipse is on the y-axis, one vertex is p (0,10), and the distance from P to a focus close to it is 2, then the standard equation is


a=10,b=8,c=6
The standard equation is y ^ 2 / 100 + x ^ 2 / 36 = 1



Two fifths multiplied by seven fourths x minus seven fifths equals two-thirds X


2/5*(7/4x-7/2)=2/3x
7/10X-7/5=2/3x
7/10x-2/3x=7/5
1/30x=7/5
x=42



What does cos (a + b) open equal


Cos (a + b) is equal to - COSC



If AB < 0 and BC < 0 are known, then the line ax + by = C passes ()
A. The first, second and third quadrants B. the first, second and fourth quadrants C. The first, third and fourth quadrants D. the second, third and fourth quadrants


The line ax + by = C is y = - AB & nbsp; X + CB, ∵ AB < 0, BC < 0, and the slope k = - AB > 0. The intercept CB of the line on the y-axis is < 0, so the first, third and fourth quadrants of the line are selected as C



Given integers a, B and C, let the equation (x + a) (x + b) + C (X-10) = (X-11) (x + 1) hold for any x, and find the value of C


(x + a) (x + b) + C (X-10) = (X-11) (x + 1) x ^ 2 + (a + B + C) x + ab-10c = x ^ 2-10x-11 (a + B + C + 10) x = 10c-ab-11 because the equation holds for any x, so a + B + C + 10 = 0, 10c-ab-11 = 0, that is, a + B = - 10-C AB = 10c-11 a, B is the two integer solution of the equation x ^ 2 + (10 + C) x + (10-11) = 0



How to solve the equation that [10x + (6-x)] - [(6-x) * 10 + x] equals 18,


It is reduced to 10x + 6-x-60 + 10x-x = 18, 18x = 72, x = 4
