Simplified, their slopes multiply to -1.
What that means is that if there's a equation
, if a line is perpendicular , that line's m value multiplied by this line's m value equals -1. For example, if m=1/4 for one value, the first thing we do is make it negative to get -1/4. Next, we switch the numerator and denominator to get -4. If there is a number like 5, the fraction of it is 5/1 (since 5 divided by 1 is 5) and the reciprocal (or the numerator and denominator switched) is 1/5. This also applied to y=mx+b.

6 is the awser ny freaind .........
Answer:
11.5 does
Step-by-step explanation:
First of all you times 2.16.... by 100 to get 21.61616.....
you then minus the original number to get 21.4.
You can then times that by 10 to why 214 and you can divide 214 by 99:
214/99 = 2.161616
Hope this helps! :)
0 because z has to be the same number on each side and 0 times 8 is 0
