Answer:
17
Step-by-step explanation:
Order the numbers from Smallest to Largest...
9, 10, 14, 15, 19, 21, 21, 27
Then the middle number is your answer.
Since there are 2 Middle Numbers, you add them together, and divide by 2.
Which would be, 17.
First of all, the first power of 'x' is the highest power in the whole equation,
so we only expect one solution.
You said that <span><u>3x+9 = 21+7x </u>
Subtract 3x from each side:
9 = 21 + 4x
Subtract 21 from each side:
-12 = 4x
Divide each side by 4 :
<u>-3 = x </u>

Answer:
S12 for geometric series: (-7.5) + 15 + (-30) + ... would be: 10237.5
Step-by-step explanation:
Given the sequence to find the sum up-to 12 terms
As we know that
A geometric sequence has a constant ratio 'r' and is defined by
∵ 
Thus, S12 for geometric series: (-7.5) + 15 + (-30) + ... would be: 10237.5
The true statement is that colony 2 will always have more bacteria than colony 1 after 4 months
<h3>How to determine the number of months?</h3>
The functions are given as:
- Colony 1: f(x) = x^2
- Colony 2: g(x) = 2^x
When colony 2 has more bacteria than colony 1, then it means that:
g(x) >f(x)
Substitute the function values
2^x > x^2
From the graph of both functions, we have:
2^x > x^2 at x >4
This means that colony 2 will always have more bacteria than colony 1 after 4 months
