b=14
Given
Michonne's Phone service charges $18.09 for an activation fee plus $2 for every gigabyte(g) used
Show the graph model for the above sitution.
To proof
As given in the question
Michonne's Phone service charges = $18.09
activation fee plus for every gigabyte(g) used = $2
let the gigabyte used be = x
let the total charges of phone = y
Than the equation become in the form
18.09 + 2x =y
the graph is shown as below.
Hence proved
Answer:
(1/7)(-9n + 7)
Step-by-step explanation:
1/7-3(3/7n-2/7) can be factored: factor out 1/7.
We get: (1/7)[1 - 3(3n - 2)], or
(1/7)[1 - 9n + 6], or
(1/7)(-9n + 7)
The domain of a real function will be all the places where the denominator isn't zero and the radicand in the square root isn't negative.
So find the places where the denominator vanishes or the square root is of a negative number and exclude those places from the domain.
