A. you would put in 7 for X and 3 for Y.
3 + 7 = 10
2(10) = 20
To solve this we are going to use the half life equation
Where:
is the initial sample
is the time in years
is the half life of the substance
is the remainder quantity after
years
From the problem we know that:
Lets replace those values in our equation to find
:
We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be
91.7 grams.
Hello :) please refer to the pic below!
Answer:
y-4=(-1/2)(x-4)
Step-by-step explanation:
Slope=(8-4)/(-4-4)=-4/8=-1/2
The equation of the line is y-4=(-1/2)(x-4)
What about if you use the distributive property? You could do 1(x+13) because the 1 would distribute to the x and the 13 making it x+13. Hope that is helpful.
