What is the axis of symmetry for the graph of this equation?

Mathematics

<h2>Hello!</h2>

The answer is: The axis of symmetry is: x=1

<h2>Why?</h2>

The axis of symmetry is a vertical line that divides the function (parabola)into two congruent halves, and it can be found using the following equation:

x=-\frac{b}{2a}

From the given function (parabola) we have that:

a=2\\b=-4\\c=2

So, finding the axis of symmetry we have:

x=-\frac{-4}{2*2}=\frac{4}{4}=1

So, the axis of symmetry is: x=1

Have a nice day!

Answer:

Length of the room is   180 ft

Step-by-step explanation:

We have a rectangular room with dimensions:

width  =  70  ft       and  length    "x" (unknown)

Perimeter of a rectangle   is   2*w  +  2*x    and according to problem statement 500 ft of lights will fit exactly in room perimeter then:

2*70  +  2*x   =  500

140  + 2*x  =  500

2*x  =  500 - 140

2*x  = 360

x  = 360/2

x  =  180  ft

Answer:

∠CDE = 76

Explanation:

1) Find ∠CED

- 180 - 116 = 64

2) Find <em>y</em>

- 4y + 7y + 6 + 64 = 180

- 11y + 70 = 180

- 11y = 110

- y = 10

3) Substitute 10 for <em>y</em>

- 7y + 6

- 7(10) + 6

- 70 + 6

= 76
