One form of the relation of inverse variation is y = k/x.
first step: Find the value of k: Taking the values x=5 and y = 4, 4=k/5, or k=20. Then, y = 20/x.
Next: Let y = 7 and find the corresp. value of x: 7=20/x, or 7x=20, or
x = 20/7 (answer)
5.333 OR 5 1/3
just plug it in the calculator
you will get your answer
Yes it is correct.........
Answer:
gotta be answer A
Step-by-step explanation:
