X^4 - 5x^12 + 9x^10 - 5x^8 - 5x^6 + 9x^4 - 5x^2 + 1
Answer: The constant proportionality is 5/4
Step-by-step explanation: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
