Answer:
(a+b)/c
Step-by-step explanation:
a/c+b/c
since they have the same denominator you can add the numerator together
(a+b)/c
If the parabola has y = -4 at both x = 2 and x = 3, then since a parabola is symmetric, its axis of symmetry must be between x = 2 and x = 3, or at x = 5/2. Our general equation can then be:
y = a(x - 5/2)^2 + k
Substitute (1, -2): -2 = a(-3/2)^2 + k
-2 = 9a/4 + k
Substitute (2, -4): -4 = a(-1/2)^2 + k
-4 = a/4 + k
Subtracting: 2 = 2a, so a = 1. Substituting back gives k = -17/4.
So the equation is y = (x - 5/2)^2 - 17/4
Expanding: y = x^2 - 5x + 25/4 - 17/4
y = x^2 - 5x + 2 (This is the standard form.)
Answer:
The equation in standard form that models area of pumpkins is:

and the area is: 
Step-by-step explanation:
Given that the garden has corn and pumpkins
The expressions are:
Total area of garden: 
Area of Corn: 
Area of Pumpkins: 
The sum of areas of corn and pumpkins is the total area of the garden.
It can be expressed mathematically as:

If we have to find the area of pumpkins,
