Question

(b) If x and y vary inversely, find the constant variation and complete the table. (a) 5 3 6 8 10 1 20 у (b) 80 40 8 20 y 2. 5​

Answer 1

Answer:

Since x and y are inversely proportional, we know that y=xConstant⇒xy=Constant

⇒8×Y1=16×5

⇒8Y1=80

⇒Y1=880=10

Now,

⇒X1×4=16×5

⇒4X1=80

⇒X1=480=20

Now,

⇒X2×2=16×5

⇒2X2=80

⇒X2=280=40

Now,

⇒80×Y2=16×5

⇒80Y2=80

⇒Y2=8080=
