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:
10*5 = 50
10*4 = 40
5 * 4 = 20
The total is 110 but we can't forget there are 2 sides to each of those planes and so the area = 220 square meters

Answer:
C ) 6 units
Step-by-step explanation:
I' just guessing but based off of the other one is 4 then this must be at least 4.
Part A: 6 and 4x are the two factors because the initial equation was 30+20x but they factored out a 5 from both 30 and 20 to make the new equation
Part B:there are 3 terms in this expression
Part C:The coefficient of the variable X is 4
