Math problems suck. can someone me out?

y = 1/3 x +2

Step-by-step explanation:

y = -3x+7

This is in the form y= mx +b so the slope is m which is -3

We want a line the is perpendicular so the new slope is the negative reciprocal

m new = - (-1/3) = 1/3

We have the slope and a point, so we can use point slope form

y-y1 = m(x-x1)

y-1 = 1/3(x--3)

y-1 = 1/3 (x+3)

Distribute the 1/3

y-1 = 1/3 x +1

Add 1 to each side

y-1+1 = 1/3x+1+1

y = 1/3 x +2

This is in slope intercept form

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.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
