Answer:
$647.99
Step-by-step explanation:
Divide the tax rate (9.750%) by 100 to get a decimal rate of 0.09750.
Add 1 to the decimal rate to get 1.09750.
Divide that tax-included price ($647.99) by 1.09750 price to get a pretax price of $590.42.
Subtract the pretax price from $647.99 to get the sales tax amount of $57.57.

Step-by-step explanation:
We need to show whether
or
so we'll do either one of them,
we'll convert f(x) to f^-1(x) and lets see if it looks like g(x).
we can also write it as:
now all we have to do is to make x the subject of the equation.
now we'll interchange the variables
this is the inverse of f(x)
and it does equal to g(x)
Hence, both functions are inverse of each other!
This can be shown graphically too:
we can see that both functions are reflections of each other about the line y=x.
Answer:
20.5 : 61.5
Step-by-step explanation:
1:3
1 + 3 = 4
82 ÷ 4 = 20.5
ratio of 1:3
1 × 20.5 = 20.5
3 × 20.5 = 61.5
20.5 : 61.5
