Answer:
(x - 6)² = 48
Step-by-step explanation:
We can solve it by completing square:
x² - 12x - 5 = 7
x² - 12x = 12
x² - 2*6x =12
We need to use formula
a² + 2ab + b² = (a + b)²
x² - 2*6x + 6² - 6² = 12
(x - 6)² = 12 + 36
(x - 6)² = 48
M = 1/-2
7 - 6 = 1
2 - 4 = -2
slope is equal to 1 over -2
The axis of symmetry is found within the set of parenthesis with the x. If our h value of the vertex is -4, then the axis of symmetry is x = -4. D is that choice. Cannot graph it here, but your vertex is sitting at (-4, 4), it's an upside down parabola, and some other points on this graph are (-5, 0), (-3, 0), (-6, -12), (-2, -12). You could graph it using those points and the vertex without a problem, I'm sure.
The answer to this depends on the angle at which they intersect. If it intersects<span> the cylinder perpendicular to the axis then a circle is formed. </span><span>If the plane intersects the cylinder at an angle, it will form an ellipse. This will be true until the plan is parallel with the axis of the cylinder. At that point, the surface will become a rectangle.</span>
