Answer:
7.21 grams
Step-by-step explanation:
The Decay Model is given as:
When t=6587 years
The amount of grams of carbon-14 that will be present is:
There will be 7.21 grams of Carbon-14 after 6587 years.
Im not a 100% sure but my best guess would be the 3rd equation:
f(x) = (x - 1) (x + 3)
Please let me know if I was wrong, but i hope this helped you!
w+2x=16 ⇒ w=16-2x
x+2w=14 x+2(16-2x)=14
x+32-4x=14
-3x=14-32
-3x=-18 /:(-3)
x=6
w=16-2x=16-2·6=16-12=4
2y+w=-6 ⇒ 2y+4=-6
2y=-6-4
2y=-10 /:2
y=-5
