I don't understand your question fully, try to list your full problem in the future and maybe people will be able to better help you.
Yes, it's y= 1/2x because it's 1/2 miles (y) per x weeks
Hello!
Distributive property: a(b+c)=ab+ac


Minus and plus sign.

Then multiply by the numbers.


Hope this helps!
Thanks!
Have a great day!
1 quart I think tbh idk but i think .
For a better understanding of the solution provided here please find the diagram attached.
Please note that in coordinate geometry, the coordinates of the midpoint of a line segment is always the average of the coordinates of the endpoints of that line segment.
Thus, if, for example, the end coordinates of a line segment are
and
then the coordinates of the midpoint of this line segment will be the average of the coordinates of the two endpoints and thus, it will be:

Thus for our question the endpoints are
and
and hence the midpoint will be:


Thus, Option C is the correct option.
