The maximum number of mosquitoes would exist if 7.5 inches of rain fell.
We can find that by looking for the maximum value in the equation. This value always falls at the vertex. The x-value of the vertex (which is what we are looking for) can always be found through the equation -b/2a, in which a is equal to the coefficient of x^2 (-1) and b is equal to the coefficient of x (15).
-b/2a
-(15)/2(-1)
-15/-2
7.5
Answer:
12
Step-by-step explanation:
24/2=12
The x-axis shows the independent variable and the y-axis shows the dependent variable. so therefore the x-axis will be the years and the y-axis will be the subscribers. hope this helped!
12 simply because it’s right at the middle between 6 and 18 which are the the first and third multiples of the number six
X would be: 0.5, 1.5, 4.5
Y would be: 3, 9, 27
When you divide 3 by 0.5 you get six so I basically just did trial and error with all the number
