Answer:
y = 2/9
Step-by-step explanation:
y=x²
y=kx²
2= k(6)²
2= 36k
k= 1/18
The connecting formula is
y= 1/18x²
when y=? , x=2
therefore,
y= 1/18x²
y= 1/18(2)²
y= 1/18(4)
y= 2/9
Answer:
y = 18 when x = 2
Step-by-step explanation:
y ∝ x^2
y = k/x^2
Substituting 'y=2' and 'x=6' to get the value of k:
2 = k/6^2
2 = k/36
k = 36*2
= 72
Hence,
y = 72/x^2
Substituting 'x=2' to get the y-value:
y = 72/2^2
= 72/4
= 18
Hence,
when x =2, y = 18
