The inverse of the function f(x) = 1/2x + 10 is shown.

1 answer:

4 0

We have to find the inverse of the function:
f ( x ) = 1/2 x + 10
y = 1/2 x + 10
- 1/2 x = - y + 10 / * ( - 1 )
1/2 x = y - 10 / * 2
x = 2 y - 20
f^(-1) ( x )= 2 x - 20
h ( x ) = 2 x - 20
Answer:
The missing value is 20.

\text{so for this we use the unitary method.}\\
\\
\text{The number of packages of screws in 5 groups}=2345\\
\\
\text{so the number of packages of screws in 1 group}=\frac{2345}{5}\\
