Answer: b ≤ -9.5 or b ≥ 5.5

Explanation:

We use different sign for different statement that showing inequality,

Less than = <

More than = >

Less than equal to =

More than equal to =

Let b shows the real number,

The value of b is at least 5.5,

⇒ All real numbers more than 5.5 including 5.5,

b ≥ 5.5,

or If the value of b is at most -9.5,

⇒ All real numbers less than -9.5 including -9.5,

b ≤ -9.5

Thus, the required inequality is b ≤ -9.5 or b ≥ 5.5
