[ 1/1Inequality]
Assignment:Find the solution set of inequality (2*t+6.4)*[(88.78+7.9*t)/(10.6+t)] >144 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * t + 6.4 ) * ( ( 88.78 + 7.9 * t ) / ( 10.6 + t ) ) >144 (1)
From the definition field of divisor
10.6 + x ≠ 0 (2 )
From inequality(1):
-10.891998 < t < -10.6 或 t > 5.567948
From inequality(2):
t < -53/5 或 t > -53/5
From inequalities (1) and (2)
-10.891998 < t < -10.6 或 t > 5.567948 (3)
The final solution set is :
-10.891998 < t < -10.6 或 t > 5.567948Your problem has not been solved here? Please take a look at the hot problems !
