The vertex is in essence the turning point of the parabola y = x²<span> − 10x + 2
the x coordinate of the turning point = </span>
=
= 5
when x = 5, y = (5)² - 10(5) + 2
= -23
Thus coordinate or vertex is ( 5, -23)
I can help you because I know how to convert fractions to mixed numbers, but what is the question exactly?
The computation shows that the price of the used computer is $75.
<h3>How to compute the price?</h3>
From the information given, it should be noted that there are 5 members before the new members joined and $15 was given to each member.
Therefore, the price of the used computer will be:
= $15 × 5
= $75
The price of the used computer is $75.
