Answer:
Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let denote the number of rafts seating 3 people and the number of rafts seating 5 people. The total number of rafts is 13, so . We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so .
It's always a good idea to put these equations under each other:
We can subtract the first equation three times from the second one to obtain
Now, substitute this found value for into and we see that . We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Answer:
OK so finding the y value is real easy this is the equstion to find it m = [y1 - y2] / [x1 - x2] If you know x, you can solve for y to find the y value for the slope of the line. I hope this helped
