To find the inverse of an equation, you basically do the opposite of the original equation. For example, the inverse of 4/2 is 2*x=4 (or 2*2)

It is opposite of what the equation is saying. Like if you had to add you would subtract or if you multiply you would divide.

Paladinen [302]

Answer:

Therefore the age of paint is 8915.78 years.

Step-by-step explanation:

Given that, the paint contain 34 % of the original carbon-14.

The exponential decay model for carbon-14 is

$A=A_0e^{-0.000121t}$

A= Remaining amount of carbon.

$A_0$ = initial amount of carbon.

Here A= 34% of $A_0$ $=\frac{34}{100}A_0$

$\therefore \frac{34}{100}A_0=A_0e^{-0.000121t}$

$\Rightarrow \frac{34}{100}=e^{-0.000121t}$

Taking ln both sides

$\Rightarrow ln|\frac{34}{100}|=ln|e^{-0.000121t}|$

$\Rightarrow ln|\frac{34}{100}|={-0.000121t$

$\Rightarrow t=\frac{ln|\frac{34}{100}|}{-0.000121}$

$\Rightarrow t= 8915.78$

Therefore the age of paint is 8915.78 years.

steposvetlana [31]

Answer:

x=1 y=-5

Step-by-step explanation:

7(5x-2y=15) ---> 35x-14y=105

2(7x+7y=-28) --> + 14x+14y=-56

49x=49 --->x=1

5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5
