Which equation represents the axis of symmetry of the function y=-2x² + 4x -6? Oy=1
Ox=1
Ox=3
Oy=3

B

Step-by-step explanation:

We are given the quadratic function:

And we want to find its axis of symmetry.

First, the axis of symmetry is always a vertical line. Hence, it should be represented by x. Thus, we can eliminate choices A and D.

Next, the axis of symmetry for a quadratic is always the x-coordinate of its vertex point. The vertex for a quadratic equation is given by:

For our function, a = -2, b = 4, and c= -6.

Therefore, our AOS is:

Hence, the equation of our axis of symmetry is x = 1.

B is our answer.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
