Line jk has an equation of a line y = 4x - 8, and line ml has an equation of a line y = 4x + 4. these two equations represent:
a) parallel lines because the slopes of the lines are the same
b) perpendicular lines because the product of the slopes is -1
c) the same line
d) lines that are neither parallel nor perpendicular

These two equations represent parallel lines because the slopes of the lines are the same.

Step-by-step explanation:

Line JK :

Line ML :

The lines are said to be parallel if they have same slopes.

The lines are said to be perpendicular if the product of their slopes is -1

Slope- intercept form:

Where m is the slope

Compare the given lines with the slope intercept form .

Line JK :

So, on comparing we get slope of line JK is 4

Line ML :

So, on comparing we get slope of line ML is 4

Since the slope of both lines are same .

So, the given lines are parallel to each other .

Hence Option A is correct.

These two equations represent parallel lines because the slopes of the lines are the same.

the answer is d. (1.2, -4.7) on edgn

hope this !

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.
