A quadratic function whose zeros are -5 and -6 is
Step-by-step explanation:
We need to write a quadratic function whose zeros are -5 and -6
Zeros of quadratic equation means x=-5 ans x=-6
We can write it as: x+5=0 ans x+6=0
Multiply both zeros:
So, a quadratic function whose zeros are -5 and -6 is

Answer:
the answer is B. 75
Step-by-step explanation:
Answer:
x = 2
y = 4
Step-by-step explanation:
y = x + 2
y = 3x - 2
From equation one, y = x + 2
So, substitute x + 2 for y into equation two
We have
x + 2 = 3x - 2
Add 2 to both sides of the equation
x + 2 + 2 = 3x - 2 + 2
x + 4 = 3x
Subtract x from both sides
x - x + 4 = 3x - x
4 = 2x
Divide both sides by by 2
4/2 = 2x/2
2 = x
x = 2
Substitute 2 for x in either of the equations to get y.
Using the first equation, we have
y = 2 + 2
y = 4
The way to distribute the eggs at the lowest cost would be using 5 cartons of 12 eggs and 1 carton of 6 eggs.
Since Timmy is helping his grandpa on his chicken farm, and he has to pack 66 eggs into cartons, minimizing the packing cost, and he can use 12-egg cartons and 6-egg cartons, and two 12-egg cartons cost as much as three 6-egg cartons, to determine how many cartons of each should be used, the following calculation must be performed:
- 2 x 12 = 3 x 6
- 24 = 18
- Thus, assuming as an example that a total of 2 cartons of 12 eggs and 3 cartons of 6 eggs cost $ 3, the value of each carton would be the following:
- 3/3 = 1
- 3/2 = 1.5
- 66/12 = 5.5
- 5 x 1.5 + 1 x 1 = X
- 7.5 + 1 = X
- 8.5 = X
In this way, the way to distribute the eggs at the lowest cost would be using 5 cartons of 12 eggs and 1 carton of 6 eggs.
