Hi there!

$\large\boxed{\text{Parallel.}}$

Rearrange the first equation into the format y = mx + b for easier comparison:

3x - y = 6

Move 3x to the other side of the equation:

-y = -3x + 6

Multiply all terms by -1:

y = 3x - 6

In comparison to y = 3x + 5, both equations have the same "m" value, or slope.

Therefore, the lines are parallel.

Deisha can build a fence in 15 hours, and Travis can build a fence in 12 hours. How long will it take them together to build a f

Basile [38]

Answer:

6 $\frac{2}{3}$

Step-by-step explanation:

Deisha's build rate = 1 fence per 15 hours = 1/15 fences per hour

Travis's build rate = 1 fence per 12 hours = 1/12 fences per hour

Working together, their combined rate is 1/15 + 1/12 = 3/20 fences per hour

So it takes them 20/3 = 6 2/3 hours per fence

On a map, two locations are 0.75 centimeter apart. Their actual distance is 15 kilometers apart.

egoroff_w [7]

If you are working out the number of KM per CM them you divide the KM by the CM:
15/0.75 = 20

This means that it is 20KM per every 1CM

Hope this helps! :)
