It has been given that y varies inversely with x, therefore the equation for this relationship is as follows;
y =
\
when y = -18 and x = 6
-18 = k/ 6 ---1)
We need to find x when y = 5
5 = k/x
when we divide 1)/2), k gets cancelled
x = -18*6/5
x = -21.6
when y = 5, then x = -21.6
y =

Answer:
Option 3
The rate of change is -5%
Step-by-step explanation:
Given : An exponential function for compounding interest,
To find : What is the rate of change?
Solution :
The general form of an exponential function is:
Where, a is the initial amount,
(1+r) is the rate of change,
r is the growth or decay factor
We have given,
Rate of change is
Convert to percent,
Therefore, Option 3 is correct.
