Answer:

B) n=-2

Step-by-step explanation:

First, distribute.

7(1+4n)-5=-38+8n

7+28n-5=-38+8n

Combine like terms.

2+28n=-38+8n

To make solving the equation easier, subtract 8n first, so there isn't a negative variable.

2+28n=-38+8n

-8n -8n

2+20n=-38

Subtract 2 on both sides.

2+20n=-38

-2 -2

20n=-40

Divide by 20 on both sides.

20n=-40

/20 /20

n=-2

Hope this helps!! Have a wonderful day :3

The table below shows some inputs and outputs of the invertible function f etc

Snowcat [4.5K]

Answer:

$(a)\ f^{-1}(-15) = -6$

$(b)\ f^{-1}(4) + f(9)=0$

Step-by-step explanation:

Given

The attached table

$(a)\ f^{-1}(-15)$

This represents an inverse function.

So, we look into x row for its value.

i.e.

$f^{-1}(-15) = -6$

$(b)\ f^{-1}(4) + f(9)$

Just like (a)

$f^{-1}(4) = -11$ ---- by looking into the x rows

$f(9) = 11$

So:

$f^{-1}(4) + f(9)=-11 + 11$

$f^{-1}(4) + f(9)=0$
