Inequality 2-3x 3-2x less than or equal to 1 how to do

（3-2x）/(2-3x) （3-2x）/(2-3x)-1 (x+1)/(2-3x) (x+1)(3x-2)>=0
=>X > = 2 / 3 or X
On the inequality of X, if the solution set of 3x 2 / 2 plus m whose absolute value is less than 1 is x greater than 2 / 3 and less than 2, then the value of M is____ Please write the process!
3/2*X+|M|
The solution set of inequality mx-2 ＜ 3x + 4 is x ＞ 6 ÷ {M-3}. What is the value range of M!

mx-3x
mx-3x
Solving inequality: 2 (1-3x) > 3x + 2
2(1-3x)>3x+2
2-6x＞3x+2
3x+6x＜0
9x＜0
x＜0
Known set a = {x} x

Given that the negative square root of X + y is - 3 and Y is the positive square root of (- 5), find the value of the algebraic formula 2x-5y
Because the negative square root of X + y is - 3, so - √ (x + y) = - 3, x + y = 9, and Y is the positive square root of (- 5), so y = 5. Then x = 4.2x-5y = 2 * 4-5 * 5 = - 17
What are the physical and electrical formulas?
Physical quantity (unit) formula remarks the deformation velocity V (M / s) v = s: distance / T: time gravity g (n) g = mg m: mass G: 9.8n/kg or 10N / kg density ρ (kg / m3) ρ = m / V M: mass V: Volume resultant force F (n) direction is the same: F = F1 + F2 direction is opposite: F combined
On the complete square formula
Given the square of X - 3x + 1 = 0, find the value of the square of X + 1 / 2 of X
x^2+1=3x
x+1/x=3
x^2+2+1/x^2=9
x^2+1/x^2=7
Divide the first formula by an X, and you will get x + x 1 / 2 = 3, then square it completely, and the result is equal to 7
When m is a positive integer, the solution of the equation 5x-3m = M-15 is not positive
Simplify first,
5x-3m / 4 = m / 2-15 / 4
5x-3m = 2m - 15
5x = 5m-15
x = m-3
When the solution of the equation is not positive, x < 0
∴m-3 ＜0
∴m＜3
When m is 1,2, the solution of the equation is non positive
Given that the complete set is r, a = {X - 2 ≤ x ≤ 5}, B = {x a + 1 ≤ x ≤ 2a-1}, and a is included in CRB, the value range of a is obtained
First, a + 1 must be 2
A is contained in CRB, i.e. 5 = 4
Or 2a-1 = 4
Because a is contained in CRB, a + 1 > = 5 or 2a-1 = 4 can be obtained
