СРОЧНО ПЖ ДАМ 30 БАЛЛОВ Довжина одиничного відрізка координатної прямої дорівнює 1см. Чому дорівнює відстань між точками А(-2) і В(7)​

Answer 1

Ответ:

Пошаговое объяснение:

7 - (-2) = 7 + 2 = 9 см

Answer 2

I can help you with your math question. The distance between two points on a coordinate line is equal to the absolute value of the difference of their coordinates multiplied by the length of the unit segment. In your case, the length of the unit segment is 1 cm, so the distance between A(-2) and B(7) is:

$$|7 - (-2)| \times 1 \text{ cm} = |9| \times 1 \text{ cm} = 9 \text{ cm}$$

This is the answer to your question. You can find more details and examples on how to calculate the distance between points on a coordinate line on this website. I hope this helps you. Have a nice day.
