50 Points for Correct answer!!

Quadrilateral WXYZ is on a coordinate plane.

Segment XY is on the line x - y = -3, and segment WZ is on the line x - y = 1. Which statement proves how segments XY and WZ are related?

A: They have slopes that are opposite reciprocals of 1 and -1 and are, therefore, perpendicular.

B: They have the same slope of 1 and are, therefore, parallel.

C: They have slopes that are opposite reciprocals of 0 and undefined and are, therefore, perpendicular.

D: They have the same slope of -1 and are, therefore, parallel.

x-y = -3  => y = x+3...........(1)  => slope = coefficient of x = 1

x-y = 1  => y = x-1 ..............(2) => slope = coefficient of x = 1

Therefore the correct statement is

They have the same slope of 1 and are, therefore, parallel.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
