B Correct answer
Explanation

For 15x^2 - 14x + 3 = 0, roots are 3/5 and 1/3 (0.6, 0.33). For 8y^2 - 26y + 21 = 0, roots are 7/4 and 3/2 (1.75, 1.5). Since all y values are greater than all x values, x < y.

AI explanation

Factoring equation I gives (5x minus 1)(3x minus 3) = 0, so x = 1/5 or x = 1. Factoring equation II gives (2y minus 3)(4y minus 7) = 0, meaning y = 3/2 or y = 7/4. Since both values of x are less than both values of y, x is less than y.
