Front

How do you find the distance between two points (x1, y1) and (x2, y2)?

Back

Use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the maximum speed limit represented by the inequality s ≤ 55?

Back

It means that the speed (s) must be less than or equal to 55.

Front

Is -2 a solution to the inequality x < -2.5?

Back

No, -2 is not a solution because it is greater than -2.5.

Front

What is the solution set for the inequality x ≤ -2.5?

Back
