Final answer:
The question seems to require finding a formula for y in terms of x and h, but the provided details are inconsistent and not clearly related to a single mathematical problem. Further clarification of the question is needed in order to provide an accurate answer.
Step-by-step explanation:
Based on the provided information, the original question appears to involve finding a formula for y in terms of x and h. However, the given details and context are not coherently linked to a single problem and instead include mathematical procedures from different scenarios that involve proportions, quadratic equations, and unit conversions.
The lack of clarity in the question makes it difficult to provide a specific formula for y in terms of x and h. Therefore, I am unable to give a precise answer with confidence.
To assist further, I would need a more detailed and specific question that directly reflects the mathematical relationship between y, x, and h that the student is trying to establish or solve.
