I need help with 1 & 3.. thanks

AlekseyPX

Answer:

y/x = (a + b) / (m + n)

Step-by-step explanation:

-(xb − ym) = -yn + xa

Distribute:

-xb + ym = -yn + xa

Combine like terms:

ym + yn = xa + xb

Factor:

y (m + n) = x (a + b)

Rearrange:

y/x = (a + b) / (m + n)

Inverse of y equals 12 to the x

e-lub [12.9K]

Answer:

$f^{-1}(x) = log_{12}(y)$

Step-by-step explanation:

We have the following function

y = 12^x, and we need to find the inverse function.

To find the inverse function we should solve the equation for "x". To do so, first, we need to:

1. Take the logarithm in both sides of the equation:

lg_12 (y) = log _12 (12^x)

(Please read lg_12 as: "Logarithm with base 12")

From property of logarithm, we know that lg (a^b) = b*log(a)

Then:

lg_12 (y) = x*log _12 (12)

We also know that log _12 (12) = 1

Then:

x = log_12(y).

Then, the inverse of: y= 12^x is:

$f^{-1}(x) = log_{12}(y)$
