m is the slope
Answer:
The number of bacteria after days is given by
where is the initial number of bacteria.
Step-by-step explanation:
The number of bacteria in the sample triples every 10 days, this means after the first 10th day, the number of bacteria is
where is the initial number of bacteria in the sample.
After the 2nd 10th days, the number of bacteria is
after the 3rd day,
and so on.
Thus, the formula we get for the number of bacteria after the nth 10-days is
where is is the nth 10-days.
Since, is 10 days, we have
or
Answer:
I think B. but thats me
Step-by-step explanation:
Answer:
y = 4x + 2
Step-by-step explanation:
You would use point slope to solve this. y-y = m(x-x) m represents the slope. With your numbers it would look like this ------> y-6 = 4(x-1)-----> distribute the 4 -----> y-6 = 4x - 4 ------> add six on both sides ------> they cancel out on the left ------> y = 4x + 2. Hope this helped!!!!
Answer:
Step-by-step explanation:
We can solve this system of equations by using elimination.
In this case, we can eliminate x by adding the two equations:
Then, substitute 7 for y to solve for x:
Substitute both these values into the system to check our answer:
Therefore the ordered pair is:
