[ 1/1Inequality]
Assignment:Find the solution set of inequality (2x-0.54)(8x+48.67)/(5.7+x) >75.75 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * x - 0.54 ) * ( 8 * x + 48.67 ) / ( 5.7 + x ) >75.75 (1)
From the definition field of divisor
5.7 + x ≠ 0 (2 )
From inequality(1):
-5.917402 < x < -5.7 或 x > 4.838027
From inequality(2):
x < -57/10 或 x > -57/10
From inequalities (1) and (2)
-5.917402 < x < -5.7 或 x > 4.838027 (3)
The final solution set is :
-5.917402 < x < -5.7 或 x > 4.838027Your problem has not been solved here? Please take a look at the hot problems !
