Your  answer is x = 3

For a quadratic of the form
  ax² +bx +c
the axis of symmetry is
  x = -b/(2a)

You have
  a = -2, b = 4
so
  x = -b/(2a) = -4/(-2*2)
  x = 1

The appropriate choice is
  b. x= 1

Which system of inequalities is shown? A. Y&gt;x y&lt;2 b. Y 2 D. Y&gt;x y&gt;2
AURORKA [14]

Answer: y > x, y > 2

The horizontal line goes through 2 on the y axis. This boundary line is represented by the equation y = 2, since every point on this line has a y coord of 2. The shading above it means that the inequality is y > 2. Every point in the shaded region of y > 2 has a y coord that is larger than 2.

The other inequality is y > x because we shade above the dashed boundary line y = x, which is that slanted dashed line.

Combining the two regions of y > 2 and y > x leads to what is shown.
