SSSSS [86.1K]

Answer:

x=0, y=1.

Step-by-step explanation:

-8x+12y= 12

-2x-12y= -12     Adding these 2 equations:

-10x = 0

x = 0.

Plug this into equation 1:

-8(0) + 12y = 12

12y = 12

A certain radioactive isotope decays at a rate of 0.3​% annually. Determine the ​half-life of this​ isotope, to the nearest year
Liono4ka [1.6K]

This could be rephrased as:

You start with 100 grams of a substance.  One year later you have 70 grams.  What is the half-life?

We need this formula:

half-life = (time * natural log (2)) / natural log (beginning amount / ending amt)

half-life = (1 year * .69315) / natural log (100 / 70)

half-life = (.69315) / 0.35667494396

half-life = 1.9433661145 years

Rounding to nearest year half-life = 2 years
