That would be .6 because that means 60 percent.

I need help with this please :)

serg [7]

Answer:

Step-by-step explanation:

this is an arithmetic sequence (we add something from element to element).

"an" describes the salary during the nth year.

a1 = $3000

a2 = a1 + 600

a3 = a2 + 600 = a1 + 600 + 600 = a1 + (3-1)×600

an = a1 + (n-1)×600 = 3000 + (n-1)×600

so,

a15 = 3000 + (15-1)×600 = 3000 + 14×600 = $11400

Find the inverse of the given function

xenn [34]

For this case, we must find the inverse of the following function:

$f (x) = \frac {5x + 1} {- x + 7}\\x\neq 7$

To find the inverse we follow the steps below:

$y = \frac {5x + 1} {- x + 7}$

We rewrite the denominator:

$y = \frac {5x + 1} {- (x-7)}\\y = - \frac {5x + 1} {(x-7)}$

We exchange variables:

$x = - \frac{5y + 1} {(y-7)}$

We solve for y:

We multiply on both sides of the equation by (y-7)

$x (y-7) = - 5y-1\\xy-7x = -5y-1$

We subtract xy on both sides of the equation:

$-7x = -5y-1-xy$

We add 1 to both sides:

$-7x + 1 = -5y-xy$

We factor for y:

$-7x + 1 = y (-5-x)$

We divide both sides by (-5-x):

$y = \frac {-7x + 1} {- 5-x}$

So, we have:

$f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}$

Answer:

$f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}$

$x\neq -5$
