Answer:
Step-by-step explanation:
First, we need to write down the equations so we can have a vision of the equations.
3x - 6y = -12
x - 2y = -8
Now we find the simpler equation, and we make it to where one of the variables is on one side.
Let's use the bottom equation.
x = 2y - 8
Now we plug in the equation to the other equation.
3(2y - 8) - 6y = -12
6y - 24 - 6y = -12
-24 = -12
0 = 12
This is a false statement. 0 does not equal 12. That means that the equation has no solutions.

Answer:
Absolute deviation is when you find the mean of a data set, then the difference between each number and the mean, then the average f the differences.
Step-by-step explanation:
Maddox: |10-9| = 1
Enrique: |10-13| = 3
Gloria: |10-9| = 1
McKenna: |10-10| = 0
Asher: |10-9| = 1
Hannah: |10-9| =
Danielle: |10-10| = 0
Katy: |10-10| = 0
Timothy: |10-11| = 1
Gentry: |10-9| = 1
Now you have the numbers: 1, 3, 1, 0, 1, 1, 0, 0, 1, 1,
Now find the mean of those numbers:

The absolute deviation is 1.
Isolate x by adding 8 to both sides.
3 = x/3
Then, multiply by 3 on both sides.
9 = x
To prove that this is right, you can imput 9 into the equation and it equals -5.
Given:
The growth of a sample of bacteria can be modeled by the function

where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,

where, b is the number of bacteria and t is time in hours.
Substituting t=3, we get the number of total bacteria after 3 hours.


Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.

Therefore, the number of total bacteria after 3 hours is about 3003.
