The value of (gof)(4) is 9 if the function f(x) is f(x) = -x³, and function g(x) is g(x) = |1/8x-1| option (B) is correct.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = -x³

Plug x = 4 in the f(x)
f(4) = -4³ = -64
Plug the above value in the g(x)

g(f(4)) = |-8-1| = |-9| = 9
Thus, the value of (gof)(4) is 9 if the function f(x) is f(x) = -x³, and function g(x) is g(x) = |1/8x-1| option (B) is correct.

Answer: 20
Step-by-step explanation: 80 - 60= 20
i hop thats what ur asking?
The answer is x=21.
since the equations are both on one side, the sum of the equations will be 180.
5x-17+2x+50=180
add the like variables.
7x+33=180
subtract 33 from 180.
7x=147
divide 147 by 7.
x=21
*to check your answer sub in 21 where the x is and the two answers together and you should get 180*
hope this helps!!
