Question

if x and y are inversely proportional find the value of x1,x2,y1, y2 in the table given below ​

Answer 1

Answer:

Since x and y are inversely proportional,

Constant

we know that y =

X

⇒ xy =

Constant

⇒ 8 x Y₁ = 16 × 5

⇒ 8Y₁ = 80

⇒ Y₁ 80 8 = 10

Now,

→ X₁ x 4 = 16 × 5

⇒ 4X₁ = 80

X2 80 2 = = 40

Feedback

Now,

⇒ 80 × Y₂ = 16 × 5

⇒ 80Y₂ 80

→ Y₂ 80 80 = 1

.. X_{1} = 20, X_{2} = 40, Y_{1} = 10, Y_{2} = 1

Hope it helps you

PLEASE MARK AS BRAINLIEST ANSWER.

80 == 4 → XI = 20

Now,

→ X₂ x 2 =

16 × 5
