Inequation:
|0,5x+1|<=0
log1/2*log5(x-2)>0
cos(t)<1/2
cos^2x>sin^2x+0,5
Identical expressions
(30x- nine)/(x- two)=> twenty-five (x+ two)
(30x minus 9) divide by (x minus 2) equally greater than 25(x plus 2)
(30x minus nine) divide by (x minus two) equally greater than twenty minus five (x plus two)
30x-9/x-2=>25x+2
(30x-9) divide by (x-2)=>25(x+2)
Similar expressions
(30x+9)/(x-2)=>25(x+2)
(30x-9)/(x+2)=>25(x+2)
(30x-9)/(x-2)=>25(x-2)
(30*x-9)/(x-2)>=25*(x+2)

(30x-9)/(x-2)=>25(x+2) inequation

You have entered [src]

30*x - 9              
-------- >= 25*(x + 2)
 x - 2

$$\frac{30 x - 9}{x - 2} \geq 25 \left(x + 2\right)$$

(30*x - 9)/(x - 2) >= 25*(x + 2)

Solving inequality on a graph

Rapid solution 2 [src]

(-oo, -7/5] U (2, 13/5]

$$x\ in\ \left(-\infty, - \frac{7}{5}\right] \cup \left(2, \frac{13}{5}\right]$$

x in Union(Interval(-oo, -7/5), Interval.Lopen(2, 13/5))

Rapid solution [src]

Or(And(x <= -7/5, -oo < x), And(x <= 13/5, 2 < x))

$$\left(x \leq - \frac{7}{5} \wedge -\infty < x\right) \vee \left(x \leq \frac{13}{5} \wedge 2 < x\right)$$

((x <= -7/5)∧(-oo < x))∨((x <= 13/5)∧(2 < x))
