To find the image of the point \( A(-5, 5) \) under a dilation with center \( (0, 0) \) and a scale factor of \( 1.2 \), you can use the formula:

\[ A' = (kx, ky) \]

where \( k \) is the scale factor and \( (x, y) \) are the coordinates of point \( A \).

In this case:

  • \( k = 1.2 \)
  • \( A(-5, 5) \), so \( x = -5 \) and \( y = 5 \).

Calculating the new coordinates:

\[ A' = (1.2 \cdot -5, 1.2 \cdot 5) \]

Calculating each coordinate:

  1. \( 1.2 \cdot -5 = -6 \)
  2. \( 1.2 \cdot 5 = 6 \)

Thus, the image of the point \( A \) after dilation is:

\[ A' = (-6, 6) \]

So, in ordered pair form, the answer is:

\[ \boxed{(-6, 6)} \]
