Question

15 N
18 8 1/3
24 6 1 / 4

The table above represents an iverse vartiation. What is the value of N?

a) 15
b) 10
c) 12 1 /2
d) 5 1 /2

Answer 1

for an inverse relation
y = k/x , where k is a constant
or
k = xy

using (18, 25/3)
k = 18(25/3) = 150

so y = 150/x
when x = 15
y or N = 150/15 = 10

check for third point, (24, 25/4)
Left side = y = 25/4
Right side = 150/(24) = 25/4

everything checks out.

Answer 2

I DON'T GET WHAT YOU MEAN REINY BUT THE ANSWER I PICKED WAS B

Answer 3
