Practice one SAT question at a time

Questions come from the Bluebook question bank.

The functions $f$ and $g$ are defined as $f (x) = \frac{1}{4} x - 9$ and $g (x) = \frac{3}{4} x + 21$ . If the function $h$ is defined as $h (x) = f (x) + g (x)$ , what is the x-coordinate of the x-intercept of the graph of $y = h (x)$ in the xy-plane?

Enter your answer

Use the exact value the question expects unless it says to round.
