[ 1/1Inequality]
Assignment:Find the solution set of inequality 1+16*(x+80)/(x+80+2000)+0.8 >= (1+16*(x+80+150)/(x+80+150+2000)) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1 + 16 * ( x + 80 ) / ( x + 80 + 2000 ) + 0.8 >= ( 1 + 16 * ( x + 80 + 150 ) / ( x + 80 + 150 + 2000 ) ) (1)
From the definition field of divisor
x + 80 + 2000 ≠ 0 (2 )
From the definition field of divisor
x + 80 + 150 + 2000 ≠ 0 (3 )
From inequality(1):
x ≥ 36954709/125000
From inequality(2):
x < -2080 或 x > -2080
From inequality(3):
x < -2230 或 x > -2230
From inequalities (1) and (2)
x ≥ 36954709/125000 (4)
From inequalities (3) and (4)
x ≥ 36954709/125000 (5)
The final solution set is :
x ≥ 36954709/125000Your problem has not been solved here? Please take a look at the hot problems !
