<span>The definition of quadratic function is given by:
</span>
<span>
So the problem asks for two conditions:
<em>1. Write the quadratic function in factored form.
</em>
<em>2. The vertex has an x-coordinate of 3.</em>
Then the equation (1) must be written as follows:
</span>
<span>
To satisfy the two conditions:
So we are free to choose the value of one root, say:
Thus:
Finally,
the answer is:
The graph of this function is shown in the figure below.</span>
Answer:
3x+2y <=30
3x represents the roses, because each rose is 3 dollars. 2y represents the carnations, because each carnation is 2 dollars. The total amount of money spent (3x+2y) should be less than or equal to 30 dollars, since the problem says that she does not want to spend more than 30 dollars.
Hope this helps!
Answer:
X=67
Step-by-step explanation:
x-22+135=180 (180 because that line is a straight line that was intersected and a straight line has a degree of 180)
x-22+135=180
x+113=180 (combine like terms)
x=67 (combine like terms again)

Answer:
Width = 5
Length = 2*5 = 10
Step-by-step explanation:
Givens
Let the width = W = x
Let the length = L = 2x
Equation
Area = L * W
Solution
Area = 2W * W Substitute into the given equation
Area = 2W^2 Simplify the right
50 = 2W^2 Divide by 2
50/2 = 2W^2 / 2 Simplify
25 = W^2 Switch
W^2 = 25 Take the square root of both sides
sqrt(w^2) = sqrt(25)
Answers
w = 5 ft
L = 2 * 5 = 10 ft
