Answer:the price for the item now it's 6.75
Step-by-step explanation:
Origin price is 45=100% after reduction comes to 85% =x
X stands for the unknown value of the reduction therefore
45=100%
X=85%
45*.85=100x
After calculation you realised the value of x reduction value it's 38.25
Hence, original price is 45 your less from the value reduced 38.25 therefore the value of the item is 6.75

The equation of the function in vertex form is y = -(x + 5)² + 4
<h3>What is quadratic equation?</h3>
A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .
Given that the quadratic function has roots at -3 and -7 and a vertex at (-5,4).
We need to find the equation of the function in vertex form
equation of the function in vertex form.
As per the information given in the question,
The given roots of the function are -3 and -7,
y = a (x + 3) (x + 7)
y = a (x² + 10x + 21)
y = a (x² + 10x + 25 − 4)
y = a (x² + 10x + 25) − 4a
y = a (x + 5)² − 4a
The vertex is (-5, 4),
So, a = -1.
y = -(x + 5)² + 4
Hence, y = -(x + 5)² + 4 is the equation of the function in vertex form
