Can someone me with this , i would really appreciate it, you!
(geometry)

  a.  B

  b.  4

  c.  BD

Step-by-step explanation:

a. Point A is at -7; point D is at +1. The distance between these points is ...

  1 -(-7) = 8

The midpoint will be 8/2 = 4 units from either end so will be at ...

  A +4 = -7 +4 = -3

or

  D -4 = 1 -4 = -3

The point located at -3 is point B, the midpoint of AD.

__

b. Having done the above calculations, we know that segment AB is 4 units long.

__

c. We also know that segment BD is 4 units long. That is because the midpoint divides a segment into two equal parts.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
