I need help on my math

shtirl [24]

Answer:

y = -5/4x - 4

Step-by-step explanation:

The equation they give you is in slope intercept form. y=mx+b. The m is the slope (-5/4). Since they want a parallel line you keep the same slope for point slope form. Point slope formula is y-y1=m(x-x1). the y1 and x1 are where you plug in the coordinates they give you.

y - 1 = -5/4x (x + 4)

y - 1 = -5/4x - 5

y = -5/4x - 4

If x=5, evaluate x^5 * x^-3

Artyom0805 [142]

Answer: 25

Step-by-step explanation:

Plug in x to the expression.

$5^5 * 5^{-3}\\$

When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.

So this simplifies to, $5^2$ .

This then solves to 25.

La edad de juan es un año menos que la tercera parte de la edad de la madre. si dentro de 5 años, la edad de la madre sera 10 añ

koban [17]

Usando un sistema de ecuaciones, se encuentra que Juan tiene 12 años e su madre tiene 39 años.

<h3>¿Qué es un sistema de ecuaciones?</h3>

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

Variable x: Edad de Juan.

Variable y: Edad de su madre.

La edad de juan es un año menos que la tercera parte de la edad de la madre, por eso:

$x = \frac{y}{3} - 1$

Dentro de 5 años, la edad de la madre sera 10 años mas que el doble de juan, por eso:

$y + 5 = 2(x + 5) + 10$

$y + 5 = 2x + 20$

Como $x = \frac{y}{3} - 1$ :

$y + 5 = \frac{2y}{3} + 18$

3y + 15 = 2y + 54

y = 39

$x = \frac{y}{3} - 1 = \frac{39}{3} - 1 = 13 - 1 = 12$

Juan tiene 12 años e su madre tiene 39 años.

Noah wants to put $1,000 in a savings account with a 1.5% annual interest rate. How much more money will he have after one year

NeX [460]

There are two types of interest: Simple interest and compounding interest:

Simple interest: F = P(1+in)
Compounding interest: F = P(1+i)ⁿ

The compounding interest is always bigger than simple interest for a given amount of n time. The effective interest rate is

Effective interest rate = 1.5%/year * 1 yr/12 months = 0.125% per month

Since there are 12 months in 1 year, n= 12. Then i = 0.125/100 = 0.00125

Difference = Compounded Interest - Simple Interest
Difference = P(1+i)ⁿ - P(1+in) = 1000(1+0.00125)¹² - 1000(1+0.00125*12)
Difference = $0.104

You will only have $0.104 more money than the simple interest.
