Answer:

Pero cuando una magnitud crece y la otra disminuye proporcionalmente, se le llama proporcionalidad Inversa. Dos magnitudes son inversamente proporcionales si al multiplicar (o dividir) una de ellas por un número, la otra queda dividida (o multiplicada) por el mismo número.

Or, But when one magnitude increases and the other decreases proportionally, it is called Inverse proportionality . Two quantities are inversely proportional if when multiplying (or dividing) one of them by a number, the other is divided (or multiplied) by the same number.

-6+14 =12-8x what is x Show steps please

Leona [35]

-6+14 =12-8x

-6+14 = 8

then

8 = 12 - 8x -12

8-12 = 12 - 12 -8x

8-12 = -4
and
12-12=0

then
-4 = -8x /-8

-4/-8 = -8x/-8

-4/-8 = 1/2

then

1/2 = x

so that: x = 1/2 = 0.5

hope that helps

What is the area of a circle whose equation is (x-3)² + (y + 1) ² =81?

kupik [55]

Okay, first, given the equation, we need to find out what the radius of the circle is. Let us state the general equation of a circle:

$\frac{(x-x_{1})^2}{r^2}+ \frac{(y-y_{1})_^2}{r^2}=1$

Where $(x_{1}, y_{1})$ is the centre of the circle. In this case, we don't need to know the centre. Just the radius.

Let us start by converting the equation into standard for, which I typed above. Divide both sides by 81.

$\frac{(x-3)^2}{81}+ \frac{(y+1)^2}{81}=1$

Great! We now know the radius of the circle. It is $\sqrt{81}$ because it is the bottom fraction. Now we know that the radius is 9.

So now lets input this into the area of circle formula:

$A=πr^2$

Now we insert our radius.

$A=9^2π$

$=A=81π$

You can convert that into a decimal if you wish.

Hope this helped!

Peyton received a graduation gift from his grandparents of $12,700. He

arlik [135]

Answer:

Peyton's account will have $13,842.18 after a year.

Step-by-step explanation:

Given that Peyton received $ 12,700 and decided to invest it for a year in an account that grants an interest of 8.8% per year, compounded semiannually, to determine the amount of money that will be in said account after the passage of one year, it is necessary to perform the following calculation:

X = 12,700 (1 + 0.088 / 2) ^ 1x2

X = 13,842.18

Therefore, after a year has passed, Peyton's account will be $ 13,842.18.
