To determine if the point \((5, 0)\) makes the equation \(y = -51x^2 + 5x + 5\) true, we need to substitute \(x = 5\) into the equation and see if the resulting \(y\) value equals 0.

Let's do the calculation:

1. Substitute \(x = 5\) into the equation:

\[
y = -51(5^2) + 5(5) + 5
\]

2. Calculate \(5^2\):

\[
5^2 = 25
\]

3. Substitute this value into the equation:

\[
y = -51(25) + 5(5) + 5
\]

4. Calculate each term:

\[
y = -1275 + 25 + 5
\]

5. Combine the terms:

\[
y = -1275 + 30 = -1245
\]

Now we have found that for \(x = 5\), \(y = -1245\), which is not equal to 0.

Thus, the point \((5, 0)\) does not satisfy the equation \(y = -51x^2 + 5x + 5\).
