19x+12y=17

step 1: move the thing that you're looking for to the left side and all the rest to the right side:

(19x +12y)-19x = 17 -19x

12y = 17 -19x

step 2: to find y, you need to get rid of 12. to do so you need to devide everything by that number:

(12y)/12 = 17/12 -19/12 x

y= 17/12 -19/12 x

step 3: simplify of possible. ( in this exercise it isnt)

step 4: rearange the equation if necessary

y= 17/12 + -19/12x

y= -19/12x + 17/12

If you invest $250.00 in an account that pays a simple interest rate of 4%, how long will you need to leave the money in the acc

labwork [276]

Answer:

Step-by-step explanation:

1. A = P(1 + rt) is the formula for simple interest where A is the final amount, P is the principal amount, r is the interest rate (annual), and t is the number of time periods, or time in years (most often)

2. $25 of interest means your total amount will be $275, so A = $275. P = $250. r = .04. We are trying to find t.

3. $275 = $250(1+.04t)

4. (275/250)(1.04) = t t = 1.05

5. This means you will need to wait 2 years to earn $25 in interest

Which of the following would have the same graphic representation as the function f(x)=16(2)^x

Zinaida [17]

The options 2 and 4 would have the same graphical representation.

Step-by-step explanation:

Step 1:

To determine which functions are equal to the question, we must assign values to x and see which values equal the function f(x) = $16.2^{x}$ .

Any random value can be assigned to x but the same value of x must be assigned to all the equations.

Step 2:

If we substitute x = 5, we get

Question; f(x) = $16.2^{x} = 16.2^{5}= 16.(32) = 512.$

Option 1; f(x) $= 4.4^{x} = 4.4^{5} = 4.(1,024)= 4,096.$

Option 2; f(x) = $4.2^{x+2} = 4.2^{5+2} = 4.(128) = 512.$

Option 3; f(x) = $32^{x} = 32^{5} = 33,554,432.$

Option 4; f(x) $= \frac{1}{4}. 2^{x+6} = \frac{1}{4}. (2^{5+6}) =\frac{1}{4}. (2048) = 512.$

So options 2 and 4 would have the same graphical representation.

<h3>Cómo construir un diagrama a partir de un enunciado</h3>

En esta pregunta debemos elaborar un diagrama de flujo, puesto que el enunciado muestra de manera evidente una clasificación de los viajeros según las ciudades de destino.

Nótese que se trata de un diagrama bastante simple, dado que no existe evidencia de jerarquización entre las ciudades mencionadas.

Tras una lectura cuidadosa del enunciado encontramos que de 25 estudiantes de cuarto grado "C" que decidieron irse de viaje, 10 viajaron a Paracas, 15 viajaron a Arequipa, 7 viajaron a los dos lugares citados y 3 viajaron a Chosica.

A continuación, presentamos el diagrama de flujo asociado a este caso en la imagen adjunta abajo.
