I did this two years ago. Hope I can help you.
Answer:
see explanation
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition that x = 9 when y = 15
15 =
( multiply both sides by 9 )
k = 135
y =
← equation of variation
So what u need to do is
46+x=180 and u will get the answer
Answer:
y = 0
Step-by-step explanation:
y =1/2(4)-2
y= 2-2
y=0
