Write any equation of the line particular to the line given by y=-2x+1 and contains the point (-3,4) -Can someone please help me with this !!

y = 1/2x + 11/2.

Step-by-step explanation:

I am going to assume that the line is perpendicular to the line where y = -2x + 1.

That means that the slope is 1/2.

So far, you have y = 1/2x + b.

To solve for b, put in the point (-3, 4).

4 = (1/2)(-3) + b

(-3/2) + b = 4

b = 4 + 3/2

b = 4 + 1.5

b = 5.5, or 11/2.

Then, you will have y = 1/2x + 11/2.

Hope this helps!

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.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
