Answer:
-1/2
Step-by-step explanation:
y2-y1 4-5 -1
--------- = -------- = --------
x2-x1 6-4 2
Since we are given with the identity of the chemical as Carbon-14, we obtain the half-life of the chemical from a reliable source and get a value of 5730 years. The equation that we are going to use for this item is,
A(t)/A(0) = (0.50)^(n/5730)
where A(t) is the current amount, A(0) is the initial amount and n is the number of years. We know from the given that the ratio of A(t) and A(0) is equal to 0.63. Substituting this to the given,
0.63 = 0.50^(n/5730)
n = 3819.48
Thus, the sample is approximately 3819.5 years old.

Answer:
all x are the solution
Step-by-step explanation:
x - 4×3 - 4×(-2x) = 3×3x + 3×4
x - 12 + 8x = 9x +12
9x + 12 = 9x + 12
9x = 9x
(0 = 0)
no matter which number we take for x the equation will always be correct
ex. x = 3 : left : 9×3 = 27
right : 9×3 = 27
