Answer:
5 millicuries
Step-by-step explanation:
Half life is 7 days which means it will be at 10 millicuries if we half that again for another 7 days then it will be 5.
If you would like to calculate 6/(x+1)-5/2=6/(3x+3), you can do this using the following steps:
6/(x+1)-5/2=6/(3x+3)
6/(x+1)-5/2=6/(3(x+1)) /*(x+1)
6 - 5/2 * (x+1) = 6/3
6 - 2 = 5/2 * (x+1)
4 = 5/2 * (x+1) /*2/5
4 * 2/5 = x + 1
8/5 - 1 = x
x = 8/5 - 5/5 = 3/5
The correct result would be 3/5.

The answer is:

<h2>
Why?</h2>
To solve the problem, we need to perform the operations and then, add like terms.
We need to apply the distributive property, which is defined by the following way:

Also, we need to remember how to add like terms. Like terms are terms that share the same exponent and the same variable, for example:

We were able to add only the first two terms since they are like terms, both are sharing the same exponent and the same variable.
So, we are given the expression:

Then, solving we have:

Hence, we have that the answer is:

Have a nice day!
Answer:
Option B
Step-by-step explanation:
Average rate of change of a function 'f' in the interval x = a and x = b is given by,
Average rate of change of change = 
Given function is,
g(x) = 
We have to calculate the rate of change in the interval [-4, 3],
Average rate of change = 
g(3) = 
= 2.5 + 1
= 3.5
g(-4) = 
= -1 + 1
= 0
Average rate of change = 
= 
= 
Therefore, Option B will be the answer.
