Answer:
y = 46
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 23 when x = 8 , then
23 = 
( multiply both sides by 8 )
184 = k
y = 
← equation of variation
When x = 4 , then
y = 
= 46

hope this helped, msg me if u want more work
Answer:
Step-by-step explanation:
x^2/100 + y^2/25=1 -----(1)
Since 25<100
Hence the above equation is of the form x^2/a^2+ y^2/b^2=1-------(2)
Comparing (1) and (2)
a^2=100
a=10
Major axis=2a=20
