Amy's yearly salary is given by the equation y = 25,000 + 700x, where x is the number of years since 2007 and y is her salary in

marissa [1.9K]

Answer:

Amy's yearly salary in 2011 was $27,800

Step-by-step explanation:

we have

$y=25,000+700x$

where

x ---> is the number of years since 2007

y ---> Amy's yearly salary in dollars

To find out what was her salary in 2011, first determine the value of x

$x=2011-2007=4\ years$

substitute the value of x in the equation above

$y=25,000+700(4)$

$y=\$27,800$

therefore

Amy's yearly salary in 2011 was $27,800

If f(x) = 7x-6, which of the following is the inverse of f(x)?

Harman [31]

Answer:

$f^{-1}$ (x) = $\frac{x+6}{7}$

Step-by-step explanation:

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

y = 7x - 6 ( add 6 to both sides )

y + 6 = 7x ( divide both sides by 7 )

x = $\frac{y+6}{7}$

Change y back into terms of x, hence

$f^{-1}$ (x) = $\frac{x+6}{7}$
