Question

Real world inequalities:

You must be 4 feet or taller to ride the roller coaster

Answer 1

`\qquad\qquad\huge\underline{{\sf Answer}}`

The required inequality that represent the given scenario is :

`\qquad \tt \dashrightarrow \:x \geqslant 4`

where, x is height in feet.

Answer 2

Let's interpret the information given:

• 4 feet or taller ⇒ the person can be 4 feet or above 4 feet

Let's set 'x' as the hypothetical height of a person

Therefore the inequality should be x ≥ 4

⇒ we put x as greater than 4 since the person must be taller than 4

feet to ride the roller coaster

⇒ we also put the '_' under the inequality to signify that the person

can equal 4 feet in height and still be eligible to ride the roller

coaster

Hope that helps!
