D. When you solve for x, you will get x=0.8528, and x=-0.8528.
X-coordinate of vertex (or axis of symmetry) of a quadratic function <span><span>f<span>(x)</span></span>=a<span>x2</span>+bx+c</span><span> is given as:</span>
<span>x=−<span>b<span>2a</span></span>=−<span>b<span>12</span></span>=−2<span>b-2b = 6 --> <span>b=<span>6<span>−2</span></span>=−<span>3

Step-by-step explanation:
1. Two angles that sum to 90° are <em>complementary</em>, whether they are adjacent or not. Angles LMN and NMP are also <em>adjacent</em>.
2. Vertical angles created by two distinct lines are <em>never adjacent</em>. The sides of the angles are created by the same lines, and the angles share a vertex, but there is no ray that is a side common to both angles.
3. Angle GMK is supplementary to angle JMG.
4. Vertical angles are congruent. See question 2.
5. See question 1.
