Answer:
The co-ordinates of the vertex of the function y-9= -6(x-1)^2 is (1, 9)
<u>Solution:</u>
Given, equation is 
We have to find the vertex of the given equation.
When we observe the equation, it is a parabolic equation,
We know that, general form of a parabolic equation is
Where, h and k are x, y co ordinates of the vertex of the parabola.

By comparing the above equation with general form of the parabola, we can conclude that,
a = -6, h = 1 and k = 9
Hence, the vertex of the parabola is (1, 9).

Answer:
$2.50
Step-by-step explanation:
The equation that describes Elizabeth's table can be found using the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (47.50 -27.50)/(3 -1)(x -1) +27.50
y = (20.00)/2(x -1) +27.50
y = 10x +17.50
Elizabeth's flat fee is $17.50. The difference between that and Mang's flat fee is ...
|17.50 -20.00| = |-2.50| = 2.50
The absolute value of the difference between the flat fees is $2.50.
3 is the answer cuz x/x cancels out and gives 1
