Answer from: GaudySky

we have

------> inequality A

The solution of the inequality A is the interval--------> (-∞,9)

All real numbers less than

$x\geq14$ -----> inequality B

The solution of the inequality B is the interval--------> [14,∞)

All real numbers greater than or equal to

The solution Inequality A or Inequality B is equal to

Solution A+Solution B

(-∞,9)U[14,∞)

The solution of the compound system of inequalities must satisfy inequality A or inequality B

we're going to verify every case

case A) $\$8$

Substitute the value of x in the inequality A and in the inequality B to verify

Verify inequality A

-------> is true

Therefore

$\$8$ is a possible value for x

You don't need to check for inequality B

case B) $\$9$

Substitute the value of x in the inequality A and in the inequality B to verify

Verify inequality A

-------> is not true

Verify inequality B

$9\geq14$ ------> is not true

Therefore

$\$9$ is not a possible value for x

case C) $\$11$

Substitute the value of x in the inequality A and in the inequality B to verify

Verify inequality A

-------> is not true

Verify inequality B

$11\geq14$ ------> is not true

Therefore

$\$11$ is not a possible value for x

case D) $\$13$

Substitute the value of x in the inequality A and in the inequality B to verify

Verify inequality A

-------> is not true

Verify inequality B

$13\geq14$ ------> is not true

Therefore

$\$13$ is not a possible value for x

case E) $\$14$

Substitute the value of x in the inequality A and in the inequality B to verify

Verify inequality A

-------> is not true

Verify inequality B

$14\geq14$ ------> is true

Therefore

$\$14$ is a possible value for x

case F) $\$15$

Substitute the value of x in the inequality A and in the inequality B to verify

Verify inequality A

-------> is not true

Verify inequality B

$15\geq14$ ------> is true

Therefore

$\$15$ is a possible value for x

therefore

the answer is

$\$8$

$\$14$

$\$15$

Answer from: XAINEE

X < 9...this is saying the hourly wage is less then 9 (not including 9)
x > = 14...this is saying the hourly wage is 14 and above

so possible values are : 8,14,15 <==
