Solve the compound inequality 2x or 57 times 86 Select the c

Solve the compound inequality. 2x>= or -5/7 times -8>6 Select the correct choice below and, if necessary. fill in the answer box to complete your choice. The solution set is .The solution set is phi.

Solution

2x >= 5 or -5x/7 -8 >6

Solve first inequality : 2x >= 5 ---> x> = 5/2

Solve second inequality: -5x/7 -8 >6

-5x/7 > 8+6----> -5x/7 > 14

x < -98/5

Now the commmon solution set from the two solution set:

x> = 5/2 or x< -98/5

There is no common set of solution from the above two sets of solution.

So, no solution. Option B
