Question 1 of 50

1. Question
Topic: Inverse proportion, Finding the Constant.

Please have pen and paper handy to show workings out. 📝

🔗 The variable $y$ varies inversely with $x$ .

Given that when $x = 90$ , $y = 10$ .

Hint

💡 Inverse variation: find k fast.

“Varies inversely” ⇒ use y = ^k⁄_x.

Turn it into a number machine.
```
x (input) ──▶ [ reciprocal (¹⁄_x) ] ──▶ [ × k ] ──▶ y (output)
```
Reciprocal means “flip” the number or variable, e.g. x → ¹⁄_x and ^a⁄_b → ^b⁄_a.

How to get k with the machine: put in x, make ¹⁄_x, then multiply by k to get y, so y = ^k⁄_x and therefore k = x × y.

💡 Inverse variation: find k fast.

“Varies inversely” ⇒ use y = ^k⁄_x.

Turn it into a number machine.
```
x (input) ──▶ [ reciprocal (¹⁄_x) ] ──▶ [ × k ] ──▶ y (output)
```
Reciprocal means “flip” the number or variable, e.g. x → ¹⁄_x and ^a⁄_b → ^b⁄_a.

How to get k with the machine: put in x, make ¹⁄_x, then multiply by k to get y, so y = ^k⁄_x and therefore k = x × y.
