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

First let's get rid of the x by multiplying the tip equation by -2
-2 (-6x - 2y = -4)
+
(-12x - 5y = -13)
Distribute
(12x + 4y = 8)
+
(-12x - 5y = -13)
x cancels out and you're left with
-1y = -5
y = 5
Now solving for x, plug in your y into one of the equations
-6x - 2(5) = -4
-6x - 10 = -4
-6x = 6
x = -1
(-1 , 5) is the solution
