Answer: -9 = a(1 - 3)² + 3
Step-by-step explanation:
Vertex Form Equation:
y = a(x - h)² + k
vertex: (h, k) which means
h = 3
k = 3
because your vertex is (3, 3).
Your point is (1, -9) which is (x, y).
This means
x = 1
y = -9
Now, plug everything into your Vertex Form Equation:
-9 = a(1 - 3)² + 3
That’s your equation and final answer, but of course, if you need to, you can solve for a if you need to.
If a is positive, the parabola opens up. If a is negative, the parabola opens down.
Hope this helps!
Answer:
12
Step-by-step explanation:
i done the butterfly method
3/4, 7/16, 5/8.....LCD = 16
3/4 = 12/16
7/16
5/8 = 10/16
I think it might be C or B I'm honestly not 100% sure.
It’s rational because the square root of 0.49 is 0.7
