It is convenient to do part b first, then use that result to do part a.
b. For some pair of points (x1, y1) and (x2, y2), you want to find a point (a, b) such that (a, b) - (x1, y1) = (x2, y2) - (a, b). That is, the differences of coordinates from one end to the center are the same as the differences from the center to the other end.
Adding (a, b) to the above equation gives
2(a, b) - (x1, y1) = (x2, y2)
Adding (x1, y1) then gives
2(a, b) = (x1, y1) + (x2, y2)
Finally, dividing by 2 gives a formula for (a, b):
(a, b) = ((x1, y1) + (x2, y2))/2
The midpoint is the average of the end points.
a. Using the result from part b, the midpoint is
midpoint = ((2, 3) + (6, 7))/2 = (8, 10)/2
midpoint = (4, 5)
Since they are adjacent complementary angles, that means angle TUV and angle VUW add to equal 90°. Since angle TUV is 80°, you subtract 80 from 90, which gives you 10°. So, this means angle VUW is 10°.
Answer:
1. it would be $0.8
2.(10,8) represents 10 potatoes cost 8 dollars
Step-by-step explanation:
1. Since we can use unit prices, we know (x,y) is (5,4), so we know 5 divided 5 is 1, and we can do 4 divided by 5 and you get 0.8, hope this will help
