Answer:

In order top to bottom: perpendicular, parallel, neither

Step-by-step explanation:

For lines to be perpendicular, their slopes must be the opposite reciprocals of each other. That means the fraction is flipped and the sign is flipped. For the first one it's 3/4 and -4/3 which is opposite reciprocals.

For lines to be parallel, the slopes are the same. The second one has both slopes = 1/2.

The last one is neither because it's not equal and they're not opposite reciprocals.

I recommend graphing these if you're still having trouble with the concept. You can try desmos.com, that's a good website to use.

The quantity of deciliters of apple juice a medium bottle contain is 10 deciliters

<h3>Equation</h3>

Large bottles = l
Medium bottles = m
Small bottles = s
Total bottles in each shelf = 64

4s + 3l = 64

3s + 2l + 2m = 64

6s + 4m = 64

m = 10

s = 4

l = 16

Check:

3s + 2l + 2m = 64

3(4) + 2(16) + 2(10)

= 12 + 32 + 20

= 64
