To identify the asymptotes of the hyperbola given by the equation:

\[ \frac{x^2}{16} - \frac{(y - 4)^2}{7} = 1 \]

we start by recognizing this as the standard form of a hyperbola centered at \((h, k) = (0, 4)\) with:

  • \(a^2 = 16\) (thus \(a = 4\))
  • \(b^2 = 7\) (thus \(b = \sqrt{7}\))

For hyperbolas of the form \(\frac{x^2}{a^2} - \frac{(y-k)^2}{b^2} = 1\), the equations of the asymptotes are given by:

\[ y - k = \pm \frac{b}{a}(x - h) \]

Substituting in our values, we have:

  • \(h = 0\)
  • \(k = 4\)
  • \(b = \sqrt{7}\)
  • \(a = 4\)

The slopes of the asymptotes will be:

\[ \frac{b}{a} = \frac{\sqrt{7}}{4} \]

Thus, the equations of the asymptotes are:

\[ y - 4 = \pm \frac{\sqrt{7}}{4}(x - 0) \]

This simplifies to:

\[ y - 4 = \frac{\sqrt{7}}{4}x \quad \text{and} \quad y - 4 = -\frac{\sqrt{7}}{4}x \]

Therefore, we can write the asymptotes as:

\[ y = \frac{\sqrt{7}}{4}x + 4 \quad \text{and} \quad y = -\frac{\sqrt{7}}{4}x + 4 \]

From the options given, the correct response for the asymptotes is:

\[ y = \frac{\sqrt{7}}{4}(x) + 4 \quad \text{and} \quad y = -\frac{\sqrt{7}}{4}(x) + 4 \]

Thus, the response "y equals Start Fraction Start Root 7 End Root over 4 End Fraction left-parenthesis x plus 4 right-parenthesis and" would be correct if it noted that the terms within parentheses correctly modify "x" lastly.

So, the final answer for the equations of the asymptotes is:

\[ y = \frac{\sqrt{7}}{4}(x) + 4 \quad \text{and} \quad y = -\frac{\sqrt{7}}{4}(x) + 4 \]
