If f(x) = 5x + 4, which of the following is the inverse of (fx)?​
lys-0071 [83]

Answer:

see explanation

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 5x + 4 ( subtract 4 from both sides )

y - 4 = 5x ( divide both sides by 5 )

\frac{y-4}{5} = x

Change y back into terms of x

f^{-1} (x) = \frac{x-4}{5}

Hal earns n dollars per hour. Next month he
xenn [34]

Answer:

Total = 1.02n

Step-by-step explanation:

Given

Earnings = n

Raise = 2\% --- <em>not 296</em>

Total = n + 0.02n

Required

Simplify the expression for total earning

The total amount is derived from:

Total = Earnings + Raise * Earnings

Total = n + 2\% * n

Express percentage as decimal

Total = n + 0.02 * n

Now, we can solve further:

Total = n + 0.02n

Total = 1.02n

<em>Hence, the simplified expression is 1.02n</em>
