Answer:
100 hours
Step-by-step explanation:
Law firm A = 350x + 22,000,
Law firm B = 410x+16,000
Where,
x = number of hours of legal assistance
What number of hours of legal assistance makes the equation 350x+22,000 = 410x+16,000 true?
Equate the legal fees of the two law firms
350x + 22,000 = 410x + 16,000
Collect like terms
350x - 410x = 16,000 - 22,000
-60x = -6,000
Divide both sides by -60
x = -6,000 / -60
= 100
x = 100 hours
The number of hours of legal assistance makes the equation true is 100 hours
ANSWER

EXPLANATION
The given function is

We need to find the inverse of this function,
Let

We interchange x an y to obtain,

We solve for y now to obtain,

We divide through by m to get,

Hence the inverse function is ,

For this inverse to exist, the denominator must not be equal to zero,
Thus

The correct answer is A.
The slope of the line is three
The fraction 5/8 is also the equation of 5 divided by 8, so we just do 5 divided by 8, which is
0.625 as a decimal.
