Assignment:Find the solution set of inequality 1+16*x/(x+2000)+0.8+4 >= (1+16*x/(x+2000)+0.15+4)*1.1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1 + 16 * x / ( x + 2000 ) + 0.8 + 4 >= ( 1 + 16 * x / ( x + 2000 ) + 0.15 + 4 ) * 1.1 (1)
From the definition field of divisor
x + 2000 ≠ 0 (2 )
From the definition field of divisor
x + 2000 ≠ 0 (3 )
From inequality(1):
x ≤ 184.300341
From inequality(2):
x < -2000 或 x > -2000
From inequality(3):
x < -2000 或 x > -2000
From inequalities (1) and (2)
x < -2000 或 -2000 < x ≤ 184.300341 (4)
From inequalities (3) and (4)
x < -2000 或 -2000 < x ≤ 184.300341 (5)
The final solution set is :
x < -2000 或 -2000 < x ≤ 184.300341 Your problem has not been solved here? Please take a look at the hot problems !
