Answer:
1024
Step-by-step explanation:
There are 4 bacteria at the start. We can make an equation to represent the phenomena explained in the question.
As it is written in the question that the bacteria culture doubles in every hour.
So,
Let t represent the unit of time
So the number of bacteria after t unit of time will be
Number of bacteria after t unit of time=4*2^t
We have to calculate number of bacteria after 8 hours, so t = 8
Number of bacteria after 8 hours=4*2^8
=4*256
=1024
So the bacteria after 8 hours in the culture will be 1024..
The y-intercept of the function is -3.
x - 3y = 9
-3y = -x + 9 / -3
y = 1/3 - 3

<h2>
Explanation:</h2>
In order to solve this problem, let's remember the point-slope form of the equation of a line:

We know two points:

So:

So this is a constant line (slope equals zero). Therefore, every point has a y-coordinate
. In other words, the equation is:

Answer:
I believe the top one is true! I'm sorry I couldn't answer them all :c
Step-by-step explanation:
The slope-intercept form:

m - slope
b - y-intercept
We have the equation in standard form.
<em>subtract 2x from both sides</em>
<em>divide both sides by (-3)</em>
