Answer:
y= -2/10 +2
Step-by-step explanation:
The equation s(n) = 20.bn is an exponential equation, and the hourly percent growth rate of the bacteria would be 85%.
<h3>How to determine the hourly percent growth rate?</h3>
The value of b is given as:
b = 1.85%
Let the hourly percent growth rate of the bacteria be r.
So, we have:
b = 1 + r
Substitute b = 1.85%
1.85 = 1 + r
Subtract 1 from both sides
r = 0.85
Express as percentage
r = 85%
Hence, the hourly percent growth rate of the bacteria would be 85%.

Answer:
Red Line: y=4
Blue Line: y=-2
Green Line: x=-1
Yellow Line: x=6
Step-by-step explanation:
Red line: the line crosses through 4 on the y axis. Therefore, y=4.
Blue line: the line crosses through -2 on the y axis. Therefore, y=-2.
Green line: the line crosses through -1 on the x axis. Therefore, x=-1.
Yellow line: the line crosses through 6 on the x axis. Therefore, x=6.
This is a bit confusing because when you see a horizontal line your mind might assume it would be an x=. Yet, it is the opposite. Hope this helps!
Using the formula a^2-b^2=(a-b)(a+b)
you get
(1/2x^2-2) (1/2x^2+2)
