Answer:

C. P'(-4,-7), Q'(-8,-7), R'(-3,3).

Step-by-step explanation:

When a shape is reflected over a line y=x, the values in the coordinates are just swapped.

P(-7,-4) becomes P'(-4,-7)

Q(-7,-8) becomes Q'(-8,-7)

R(3,-3) becomes R'(-3,3)

The answer is P'(-4,-7), Q'(-8,-7), R'(-3,3).

Juan paga por un saco S/ 224, después de que le han
grigory [225]

El saco tiene un precio original de 400 soles.

<h3>¿Cómo determinar el precio inicial de un saco comprado con descuento?</h3>

En este problema tenemos el caso de un precio de compra (P'), en soles, que es resultado de aplicar dos descuentos consecutivos al precio original del saco (P), en soles. El precio es el resultado de multiplicar el precio original por los dos factores de porcentaje, descrito por la siguiente fórmula:

P' = P · (1 - r₁ / 100) · (1 - r₂ / 100), 0 ≤ r₁, r₂ ≤ 100.

Donde:

  • r₁ - Porcentaje del primer descuento.
  • r₂ - Porcentaje del segundo descuento.

Si sabemos que P' = 224, r₁ = 30 y r₂ = 20, entonces el precio original del saco es:

224 = (1 - 30 / 100) · (1 - 20 / 100) · P

224 = 0.7 · 0.8 · P

P = 224 /(0.7 · 0.8)

P = 400

El precio original del saco es de 400 soles.
