Answer:

y=1/2x

Step-by-step explanation:

Slope intercept form is the most commonly used linear equation:

It goes like this:

y=mx+b

In this equation, m is the slope and b is the y-intercept.

Your line has a slope of 1/2. So, your m-value is 1/2.

y=1/2x+b

B, your y-intercept, is at the origin.

The origin is the point (0,0).

So b, is 0 (y-intercept is the y-value when x is 0)

y=1/2x+0

=

y=1/2x

Martha compra 2 kilos de tomate y 1 kilo de cebolla pagando S/ 8,40. Si la siguiente semana compra 1 kilo de tomate y 2 kilos de
Rashid [163]

Responder:

2,40

Explicación paso a paso:

Dado que:

Dejar :

Tomate = t

Cebolla = n

(2 kilo de t) + (1 kilo de n) = 8.40

(1 kilo de t) + (2 kilo de n) = 7.80

2t + n = 8,40 - - (1)

t + 2n = 7,80 - - (2)

De (2);

t = 7,80 - 2n

Ponga t = 7.80 - 2n en (1)

2 (7,80 - 2n) + n = 8,40

15,6 - 4n + n = 8,40

15,6 - 3n = 8,40

-3n = 8,40 - 15,6

-3n = - 7,2

n = 2,4

t = 7,80 - 2 (2,40)

t = 7,80 - 4,80

t = 3

Por lo tanto, el costo de 1 kilo de cebolla es 2,40
