Answer:

see explanation

Step-by-step explanation:

(a)

To find the x- intercepts , let y = 0 , that is

6x - x² = 0 ← factor out x from each term

x(6 - x) = 0

Equate each factor to zero and solve for x

x = 0

6 - x = 0 ⇒ x = 6

Coordinates of P (6, 0 )

(b)

The axis of symmetry is a vertical line, positioned at the midpoint of the zeros

x = \frac{0+6}{2} = \frac{6}{2} = 3

Equation of axis of symmetry is x = 3

(c)

Given a parabola in standard form y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

y = 6x - x² = - x² + 6x ← is in standard form

with a = - 1, b = 6 , then

x_{vertex} = - \frac{6}{-2} = 3

Substitute x = 3 into y = 6x - x² for y- coordinate

y = 6(3) - 3² = 18 - 9 = 9

coordinates of maximum point = (3, 9 )

Emily researched the average prices of desktop PCs worldwide since 2000. She could only find data from 2005 to 2010. She created
gregori [183]

Answer: There is a linear relationship  between the average price of PCs and the number of years that have passed since 2000.


Step-by-step explanation:

From the given graph, we can see there is a straight line , which shows that there is a linear relationship between both quantities.

As the number years increases the average price of PCs decreases.

The given equation of the line is y=-39x+998, which shows that the slope of the line is -39, i.e the rate of decrease in the average price of PCs with respect to the the number of years that have passed since 2000.
