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:
1/3 I think I did the math and if that's not right try 1/3:1/4 (<--ratio)
Step-by-step explanation:
Answer:
y = (2x + 15)/3
Step-by-step explanation:
3y = 2x + 15
Divide both sides by 3,
3y/3 = 2x/3 + 15/3
Simplify,
y = (2x + 15)/3
The zeros are at -3, 1 and 3
