To find the vertices of the given hyperbola:

The equation is:

\[ \frac{(y - 2)^2}{25} - \frac{(x + 5)^2}{9} = 1 \]

This hyperbola is in the standard form:

\[ \frac{(y - k)^2}{a^2} - \frac{(x - h)^2}{b^2} = 1 \]

Where:

  • The center of the hyperbola \((h, k)\) is \((-5, 2)\),
  • \(a^2 = 25\) so \(a = 5\),
  • \(b^2 = 9\) so \(b = 3\).

Since this hyperbola opens upwards and downwards, the vertices are located at coordinates:

\[ (h, k \pm a) \]

Substituting the values we have:

\[ h = -5, \quad k = 2, \quad a = 5 \]

Thus, the vertices are:

\[ (-5, 2 + 5) = (-5, 7) \] \[ (-5, 2 - 5) = (-5, -3) \]

Therefore, the vertices of the hyperbola are:

\[ \left(-5, 7\right) \text{ and } \left(-5, -3\right) \]

The correct response is:

left-parenthesis negative 5 comma 7 right-parenthesis and left-parenthesis negative 5 comma negative 3 right-parenthesis.
