Answer:
The equation is:
Step-by-step explanation:
The equation of a circle:
(where 
represents the center and 
the radius).
-Use the given center and radius for the equation of a circle:
After, you have the equation of a circle written, simplify the radius by the exponent 
:
So now, you have found the equation of a circle.

The given function is f(z)=3z-8 for the values f(-4), f(2) and f(z-7) respectively -20, -2 and 3z-29 respectively.
The given function is f(z)=3z-8.
We need to find the value of f(-4), f(2), f(z-7).
<h3>What is a function?</h3>
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Now to find f(-4), replace z from -4.
f(-4)=3(-4)-8=-12-8=-20
Now to find f(2), replace z from 2.
f(2)=3(2)-8=6-8=-2
Now to find f(z-7), replace z from z-7.
f(z-7)=3(z-7)-8=3z-21-8=3z-29.
Therefore, the given function is f(z)=3z-8 for the values f(-4), f(2) and f(z-7) respectively -20, -2 and 3z-29 respectively.

Answer:
let the price of a pen be x
9 pens cost 7.20, so 9x costs 7.20. Therefore,
9x = 7.20
x = 0.8
Each pen is 0.8 dollars (80 cents).
