The method of calculating 1-2 + 3-4 +... - 50 + 51

Original formula = (1-2) + (3-4) +... + (49-50) + 51
=-1*25+51
=26

Circle C passes through three different points P (k, 0), q (2, 0) and R (0, 1). It is known that the tangent slope of circle C at point P is 1. Try to find the equation of circle C

Suppose that the equation of circle C is x2 + Y2 + DX + ey + F = 0, then K and 2 are two of x2 + DX + F = 0, ∧ K + 2 = - D, 2K = f, that is, d = - (K + 2), f = 2K, and then circulates over R (0, 1), so 1 + e + F = 0. ∧ e = - 2k-1

Given the integer of M, the score of fraction 2-3m / M + 1 is an integer, and the value of integer m is obtained

(2-3m)/(m+1)=(5-3-3m)/(m+1)=5/(m+1)-3
Because the fraction is an integer, 5 / (M + 1) is an integer
m+1=±5
M = 4 or M = - 6

Given that positive real numbers x and y satisfy (1 / 1 + 2x) + (1 / 1 + 3Y) = 1 / 2, what is the minimum value of XY

x. Y is a positive real number
From (1 / 1 + 2x) + (1 / 1 + 3Y) = 1 / 2
2(1+3y+1+2x)=(1+2x)(1+3y)
4+6y+4x=1+3y+2x+6xy
6xy=3+2x+3y≥3+2√(6xy)
therefore
6xy-2√(6xy)-3≥0
Let √ (6xy) = t (T > 0), then 6xy = T ^ 2
therefore
6xy-2 √ (6xy) - 3 ≥ 0
t^2-2t-3≥0
The solution is t ≤ - 1 (rounding off) or t ≥ 3
So √ (6xy) ≥ 3
xy≥3/2
So the minimum value of XY is 3 / 2

The reciprocal of a number is 12. How many meters is one fifth of it

The reciprocal of a number is 12, and one fifth of it is = (1 / 12) × (1 / 5) = 1 / 60m
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

(5x-4y) (3x-7y) = 0 and XY ≠ 0

(5x-4y)(3x-7y)=0
So 5x-4y = 0 or 3x-7y = 0
5x = 4Y or 3x = 7Y
So x / y = 4 / 5 or X / y = 7 / 3
