Answer:
Step-by-step explanation:
Let t represent the number of years since 2005.
We have been given that the number of people afflicted with the common cold C in the winter months steadily decreased by 202 each year from 2005 until 2010.
The number of people decreased in t years would be .
We are also told that in 2005, 12,073 people were afflicted. So 12,073 will be initial value.
We will represent our given information in an equation as , where,
m = Slope of line,
b = The initial value.
Since the number of people afflicted with the common cold C in the winter months steadily decreased, so slope will be negative.
Substitute the given values:
Therefore, our required equation would be .

Answer:
area of larger triangle = 560 in²
Explanation:
We are given that the ratio between the side length of the larger triangle to the smaller one is 4:3
We can use this information to get the ratio between their areas.
To get the ratio between the areas, we will simply square the ratio between the side lengths as follows:
area of large triangle : area of small triangle
(4)² : (3)²
16 : 9
We are given that the area of the small triangle is 315 in², therefore, we can use cross multiplication to get the area of the large triangle as follows:
area of large triangle : area of small triangle
16 : 9
?? : 315
area of large triangle = (315*16) / 9
area of large triangle = 560 in²
Hope this helps :)
