TAREA 21 Resuelva el siguiente problema aplicando el método de determinantes:
Un niño ha estado ahorrando dinero en tres distintos y pequeños costales, el primero tiene la cantidad de $58.00, el segundo $41.00 y el último con $35.00. Si los costales contienen tres distintas monedas de diferente denominación con las siguientes cantidades de monedas para cada costal: en el primer costal (6,8 y 10); en el segundo costal (3 y 10); y en el tercer costal (7, 4 y 1) ¿Cuál es la denominación de cada moneda?

Alguien que sepa hacerlo no se hacerlo me puede ayudar

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
