Point form: (80,120)
X=80, Y=120
Answer:
x=10
Step-by-step explanation:
3(4x-12) = 84
Divide each side by 3
3/3(4x-12) = 84/3
4x-12 =28
Add 12 to each side
4x-12+12 = 28+12
4x= 40
Divide each side by 4
4x/4 = 40/4
x = 10
I would say take 2 from eight which equals 6
Answer:
We are given
Scientist begins with 150 milligrams of a radioactive substance
so,
we can use formula
we can plug Po=150
After 29 hours, 75 mg of the substance remains
so, at t=29 , P=75
we can plug it
now, we can solve for k
now, we can take ln on both sides
now, we can plug it back
and we get
we can plug t=33
we get
