Y is inversely proportional to x when y=7,x=9

What is the missing constant term in the perfect square that starts with x^2 -20x

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2

Divide reduce the answer to lowest term 3/7 divided 1 1/6
