All real numbers at most –9.5 or at least 5.5 is given by \(b \leq -9.5\) or \(b \geq 5.5\)

Answer: b ≤ -9.5 or b ≥ 5.5

Step-by-step 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
