[ 1/1Inequality]
Assignment:Find the solution set of inequality (2x-0.9)(8x+46.02)/(5.4+x) >75.75 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * x - 0.9 ) * ( 8 * x + 46.02 ) / ( 5.4 + x ) >75.75 (1)
From the definition field of divisor
5.4 + x ≠ 0 (2 )
From inequality(1):
-5.597719 < x < -5.4 或 x > 5.029594
From inequality(2):
x < -27/5 或 x > -27/5
From inequalities (1) and (2)
-5.597719 < x < -5.4 或 x > 5.029594 (3)
The final solution set is :
-5.597719 < x < -5.4 或 x > 5.029594Your problem has not been solved here? Please take a look at the hot problems !
