Given y varies inversely as x, and y = 5 when x = 9. Write the inverse function

Answers

Answer:

y = 45/x

Step-by-step explanation:

Given y varies inversely as x, then;

y = k/x

If y = 5 when x = 9

5 = k/9

k = 5*9

k = 45

Substitute into the formula above;

y = k/x

y = 45/x

Hence the required inverse function is y = 45/x

En la tienda de electrónica Se vende un televisor en 15480 pesos pero tendrá un descuento del 35% de su precio entonces cuánto costará el televisor y con el descuento

Answers

Respuesta:

Monto descontado = 5,418pesos

Nuevo precio de la televisión = 10.062 pesos

Explicación paso a paso:

Costo inicial de televisión = 15,480 pesos

Porcentaje de descuento = 35%

Cantidad descontada = 35% de 15,480

Cantidad descontada = 0.35 * 15,480

Monto descontado = 5,418pesos

Nuevo precio de la televisión = 15.480 - 5.418

Nuevo precio de la televisión = 10.062 pesos

How to calculate the perimeter of a rectangle?

A rectangle is a 2-D shape with 4 angles. The formula for calculating the perimeter of a rectangle is expressed as:

P = 2(length + width)

Given

Perimeter = 30 feet

width = 12 ft

Substitute

30 = 2(l + 12)

15 = l + 12

l = 3 feet

Hence the length of thegarden if it is 12 feet wide is 3 feet
