Answer:
the inverse for each relation:
1. {(1,-2), (2, 3),(3, -3),(4, 2)} is
<u>{</u><u>(</u><u>-</u><u>2</u><u>,</u><u>1</u><u>)</u><u>,</u><u>(</u><u>3</u><u>,</u><u>2</u><u>)</u><u>,</u><u>(</u><u>-</u><u>3</u><u>,</u><u>3</u><u>)</u><u>,</u><u>(</u><u>2</u><u>,</u><u>4</u><u>)</u><u>}</u><u>.</u>
So, you divide 18 by 12 to get 1.5
but since you want the fraction, just reduce 18/12 as much as possible to get 3/2
(I don't know what your question is, but if you're asking about the rate, I got it.)
Answer: 2.6666... meters per second
Explanation/Calculation:
Divide 40 by 15 to get the rate. You get 2 2/3 meters or 2.6666... meters per second.
Hope this helps! :)
