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:
6.75$
Step-by-step explanation:
because 15% of 45$ is 6.75$
Unless there are restrictions on the domain, the range of any odd-degree polynomial function is (-∞, ∞), that is, all real numbers.
A linear function has degree 1, an odd degree.
Answer:
3x−4>11
Step 1: Add 4 to both sides.
3x−4+4>11+4
3x>15
Step 2: Divide both sides by 3.
> 
x>5
