Alekssandra [29.7K]

Answer:

a) Escribe un sistema de ecuaciones para representar esta situación.

x + y = 81 ...... Ecuación 1

x - y = 33 ....... Ecuación 2

b) Los dos números son: 57 y 24

Step-by-step explanation:

Estamos tratando con 2 números

Dejar

El primer número = x

El segundo número = y

La suma de dos números es 81.

x + y = 81 ...... Ecuación 1

La diferencia de los mismos dos números es 33.

x - y = 33 ....... Ecuación 2

Escribe un sistema de ecuaciones para representar esta situación.

x + y = 81 ...... Ecuación 1

x - y = 33 ....... Ecuación 2

Resolvemos estas ecuaciones usando el método de eliminación

Restamos la ecuación 2 de la ecuación 1 para eliminar

2y = 48

y = 48/2

y = 24

Resolver para x usando la Ecuación 1

x + y = 81 ...... Ecuación 1

x + 24 = 81

x = 81 - 24

x = 57

Por lo tanto, los dos números son: 57 y 24

LOOK AT CHART BEFORE THE BULLET PART:
tresset_1 [31]

Answer:

  • m = -3/4
  • y-intercept = 399
  • slope-intercept equation: y = -3/4x + 399

Step-by-step explanation:

It can be easiest simply to solve the equation for y.

  3x + 4y = 1596

  4y = -3x + 1596 . . . . subtract 3x

  y = -3/4x + 399 . . . . divide by 4

From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.
