Answer:
1 + root 5, 1 - root 5
Step-by-step explanation:
I assume you mean 3x^2-6x-12=0.
First, note that you can divide both sides by 3. You get:
x^2-2x-4=0
Use the quadratic equation.
Therefore, x=1 + root 5, 1 - root 5
Think of it like this
3.99 x 3=11.97
Divide by 4
Should give u 2.99
^^^there is your answer
x = number of hours after 9 am (eg: x = 1 means 1 hr after 9 am, so 10 am)
f(x) = population count x hours after 9 am
f(1) = population count at 10 am (1 hour later)
f(2) = population count at 11 am (2 hrs after 9 am)
f(2) - f(1) represents the difference in population counts from 10 am to 11 am, or put another way, how much the population increased during that time interval.
Answer: I think that is the answer I solve it as they sealed me
f(x)=0.25
Step-by-step explanation:
f(x)=1/3*4(2)
f(x)=0.25
1 quart= 4 cups
1:4 is your ratio
