In the plane rectangular coordinate system, if the distance between point m (1,3) and point n (x, 3) is 5, then the value of X is 0___ .

In the plane rectangular coordinate system, if the distance between point m (1,3) and point n (x, 3) is 5, then the value of X is 0___ .


∵ the distance between point m (1,3) and point n (x, 3) is 5, | X-1 | = 5, and the solution is x = - 4 or 6. So the answer is: - 4 or 6



In the plane rectangular coordinate system, given that the point m is the point above the x-axis, and the distance from the point m to the x-axis is 5, and the distance from the point m to the y-axis is 3, the coordinate of M is obtained


M (- 5,3), m (- 5, - 3), m (5,3), m (5, - 3), there are four points



In the rectangular coordinate system, there are four points a (- 6,3), B (- 2,5), C (O, m) d (n, 0). When the perimeter of the quadrilateral ABCD is the shortest, find the value of M, n


m=3,n=-3,
In short, the sum of the two sides of the triangle is greater than the third side, that is, points c, D and a are symmetric to the x-axis, points A1 and B are symmetric to the y-axis, and four points are on the same line!
Detailed drawing you know!



In the rectangular coordinate system, let a (4, - 1), B (2, - 3), C (m, 0), D (0, n) find the value of M, n when the perimeter of quadrilateral ABCD is the smallest


A about X-axis symmetric point a '(4,1)
B on the y-axis symmetric point B '(- 2, - 3)
Connect a'B ', intersect X-axis with C, intersect Y-axis with D
Straight line a'B ': y = 2x / 3-5 / 3
C(2.5,0) M=2.5
D(0,-5/3) N=-5/3
