Well, first you want to try and figure out exactly how much is your y increasing by. On the table in your image your y is increasing by 30. What I would do is keep increasing your x's by one and then your y's by 30 till you reach what y equals if x is 12.

x y
4 120
5 150
6 180
7 210
8 240
9 270
10 300
11 330
12 360

HOPE THIS HELPS! ^_^

butalik [34]

Change these equations into the equations of linear functions.
$\left \{ {{4x-2y=22} \atop {6x+9y=-3}} \right. \\ \\
 \left \{ {{-2y=-4x+22} \atop {9y=-6x-3}} \right. \\ \\
 \left \{ {{y=2x-11} \atop {y=-\frac{2}{3}x-\frac{1}{3}}} \right.$

Draw function graphs and read coordinates of the intersection.
$\left \{ {{x=4} \atop {y=-3}} \right.$

¿Cuántas libras de café “La Finca” que se vende a $5 la libra debe mezclarse con 80 libras decafé común que se vende a $2 la lib

Romashka-Z-Leto [24]

Answer:

Necesitamos agregar 40 libras del café La Finca

Step-by-step explanation:

Sea x el número de libras de café de La Finca a mezclar.

Entonces, la cantidad total de libras que obtendremos en la mezcla será (x + 80) libras.

Ahora trabajemos con los precios; Tenemos x libras de La Finca a $ 5 por libra, con 80 libras de café a $ 2 por libra para dar una mezcla de (x + 80) a $ 3 Así, sumaremos el precio de La Finca más la otra variante para llegar al costo de la nueva mezcla.

Matemáticamente;

5 (x) + 2 (80) = 3 (x + 80)

5x + 160 = 3x + 240

5x -3x = 240-160

2x = 80

x = 80/2 x = 40
