Answer:

(1, 6)

Step-by-step explanation:

3x + y = 9

y − 2x = 4 → y = 2x + 4

Use the substitution method:

3x + y = 9 → 3x + (2x + 4) = 9 → x = 1

Then,

y = 2x + 4 → y = 2(1) + 4 → y = 6

What situations can you model with one-step equations?​
aksik [14]

Answer:

Muchos de los problemas de las ciencias, economía, finanzas, medicina y otros numerosos campos se pueden traducir a problemas de álgebra. Ésta es una razón por la

que el álgebra es tan útil. En esta sección usamos las ecuaciones como modelos

matemáticos para resolver problemas de la vida cotidiana.

Criterios para modelar con ecuaciones

Se aplican los siguientes criterios para plantear ecuaciones que modelen situaciones

formuladas en palabras. Para mostrar la manera en que los criterios pueden ayudar a

plantear las ecuaciones, anotamos al margen cuándo funciona cada ejemplo de esta

A total of $12,000 is invested at an annual interest rate of 9%. Find the balance
sineoko [7]

Answer:

$18,726.11

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First lets change 9% into a decimal:

9% -> \frac{9}{100} -> 0.09

Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:

A=12,000(1+\frac{0.09}{4})^{4(5)}

A=18,726.11

<u>The balance after 5 years is $18,726.11</u>
