I think it would be y=2(4x+200)
2 being it doubled and x would be to insert the twelve in to solve, and you add the 200 bacteria you already have.
Answer:
Part 1) The graph in the attached figure
Part 2) The equation of the line is
Step-by-step explanation:
Part 1) we know that
To graph a line we need at least two points
we have
(5,2) and (0,7)
Plot the points
Connect then and join to graph the line
The graph in the attached figure
Part 2) Determine the equation of the line
Find the slope
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
see the graph
The formula to calculate the slope between two points is equal to
we have
substitute
Is negative because is a a decreasing function
as the value of x increases, the value of y decreases
The equation of the line in slope intercept form is equal to
we have
----> the y-intercept is given see the graph
substitute
A set of ordered pairs, like the ones shown, represents a function only if each of the first coordinates is not repeated.
For example {(2, 5), (7, 8)} is a function, but {(2, 3), (6, 8), (2, -1)} is not because 2 is repeated.
We can check that each set of pairs we are given, are functions.
The inverses of each of these sets would be :
<span>{(–2, –1), (4, 0), (3, 1), (14, 5), (4, 7)} 4 repeats
{(2, -1), (4, 0), (5, 1), (4, 5), (2, 7)} 4 and 2 repeat
{(3, -1), (4, 0), (14, 1), (6, 5), (2, 7)} no repetition of 1st coordinates
{(4, -1), (4, 0), (2, 1), (3, 5), (1, 7)} 4 repeats
</span>
So only the inverse of <span>{(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} is also a function</span>
Answer: Option 'c' is correct.
Step-by-step explanation:
Advantages of filling tax return online:
1) It allows for greater accuracy when filling as online system is faster in updating and verifying the details of individual.
2) It allows for faster receipt of any refund due as it gives you print pdf of receipt of any refund due , don't need to go and make a queue to pay the bills or to get refund.
Hence, II and III are correct.
Therefore, Option 'c' is correct.
