Assignment:Find the solution set of inequality (0.7602+0.1*x*0.7602)/(0.5247+0.1*x*0.5247) <2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 0.7602 + 0.1 * x * 0.7602 ) / ( 0.5247 + 0.1 * x * 0.5247 ) <2 (1)
From the definition field of divisor
0.5247 + 0.1 * x * 0.5247 ≠ 0 (2 )
From inequality(1):
x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
From inequality(2):
x < -10 或 x > -10
From inequalities (1) and (2)
x < -10 或 x > -10 (3)
The final solution set is :
x < -10 或 x > -10Your problem has not been solved here? Please take a look at the hot problems !
