Answer:
<h2>D. y - 5 = 2/3(x + 3)</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

We have the slope 2/3 an the point (-3, 5). Substitute:

Answer:
-1
Step-by-step explanation:
lim x tends to 4 (x^2-9x+20)/(x-4). (x^2-9x+20)(x-4)=x-5.
So the limit is 4-5=-1
Answer: I know C it’s one answer

For half lives

A=final amount
P=present amount
t=time in some units (this case it is days)
h=half life in days in th is case
so
given
we want 5% left
so A=5% of P or 5/100 of P or 1/20 of P or 0.05P
h=4.6
so

divide bth sides by P

take ln of both sides



divide both sides by


times both sides by 4.6
