Answer:
Hi there, this should be the correct answer!
x = -1 - 1/2y
y = -2 - 2x
Step-by-step explanation:
Work I did, hope this helps:
y + 4 = -2x + 2
y + 2x = -2
2x = -2 - y
x = -1 - 1/2y
y = -2 -2x
Hope this helped!
Answer:
t=6
Step-by-step explanation:
4= -8+2t so ur answer is
t=6
Answer:
2.25
Step-by-step explanation:
Because if you do 8/6 you get 1.33333333333 so you would need to do 3/1.33333333333 and you would get 2.25.
Step-by-step explanation:
1. So first you have to cross multiple the two terms
2.Solve the algebraic equation
By dividing with 12 on both sides
(Note :That's a 32 in the picture sometimes i really write bad)
At death means x= 0, so on the graph you can see that (0, 500), so 500 carbon atoms are present at death.
Plug 11,240 in for t in the equation, and you are left with N(t) = 500(1/2)^2 = 125 carbon atoms.
See the graph point (25,000, 24.298)? That means that after 25,000 years 24.298 carbon atoms will be present. So the answer is 25,000 years.
