Question

y varies inversely with twice the value of x. When y = 10, x = 3. Find y when x = 5

Answer 1

"y varies inversely with twice the value of x."
\[y=k\frac{ 1 }{ 2x }\]

Answer 2

When y = 10, x = 3. \[(10)=k\frac{ 1 }{ 2(3) }\]\[10=k\frac{ 1 }{ 6 }\]both sides times 6:\[60=k\]

Answer 3

10=k(1/6)
60=K

Y=60(1/5)
Y=12

Answer 4

thanks up so much dss
