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.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
