[ 1/1Inequality]
Assignment:Find the solution set of inequality (2*t+6.8)*[(82.08+7.9*t)/(10.8+t)] >144 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * t + 6.8 ) * ( ( 82.08 + 7.9 * t ) / ( 10.8 + t ) ) >144 (1)
From the definition field of divisor
10.8 + x ≠ 0 (2 )
From inequality(1):
-10.8 < t < -10.618732 或 t > 5.942782
From inequality(2):
t < -54/5 或 t > -54/5
From inequalities (1) and (2)
-10.8 < t < -10.618732 或 t > 5.942782 (3)
The final solution set is :
-10.8 < t < -10.618732 或 t > 5.942782Your problem has not been solved here? Please take a look at the hot problems !
