Need help idk how to slove this
Gemiola [76]

Hi!

I'm not sure how to slove this, but I do know how to solve it ;D

<h3>We can't know the exact value of y, but we can isolate y on one side. First, multiply by z on both sides. </h3>

\frac{x+y}{z*z}=3*z

x + y = 3 * z

<h3>Now subtract x from both sides.</h3>

x - x + y = 3 * z - x

<u>y = 3 * z - x</u>

<h2>The answer is y = 3 * z - x</h2>

Hope this helps! :)

Points A(-2, 4), B(1, 3), C(4, -1) and D form a parallelogram. What are the coordinates of D?
Rudik [331]
Let point A(-2,4)  = A (X1,Y1)
      point B( 1,3  )= B (X2,Y2)
      point C(4,-1)  = C (X3,Y3)
and point D(?, ?) = D (X4,Y4)  We have to find this point

To find X4 we have to use the formula:
X2-X1=X3-X4

Now just plug in the numbers that correspond to the letters provided:
(1)-(-2)=(4)-(X4) ----> we don't know what X4 is yet, so we have to solve for it!
1+2=4-X4
3=4-X4
3-4=-X4
-1=-X4  divide both sides by -1
X4=1

Now we have to find Y4 using this formula:
Y2-Y1=Y3-Y4

Therefore,
(3)-(4)=(-1)-(Y4)
-1=-1-Y4
-1+1=-Y4
0=-Y4
So,
Y4=0


Now we have found the coordinates of the point D, which is (1,0)

Hope this helped!

Valentin [98]
I think the answer you are looking for is 99%.

100 + 10% = 110. 110 - 10% = 99. that’s how i got 99.

Consultar sobre las propiedades de la potenciacion y la radicacion y para cada uno dar 2 ejemplos
Nataly_w [17]

Answer:

Potencia de una potencia

La potencia de una potencia de base a es igual a la potencia de base a elevada a la multiplicación de ambos exponentes -

Potencia de base 10

En las potencias con base 10, el resultado será la unidad seguida de tantos ceros como indica la cifra del exponente

radiacion

En matemáticas, la radicación es el proceso de hallar raíces de orden n de un número a.1​.  

De modo que se verifica que  

x n = a {\displaystyle x^{n}=a}  

, donde n es llamado índice u orden, a es llamado radicando, y x es una raíz enésima.2​3​  

La raíz de orden dos de  

a {\displaystyle a}  

, se llama raíz cuadrada de  

a {\displaystyle a}  

y se escribe como  

a {\displaystyle {\sqrt {a}}}  

o también  

a 2 . {\displaystyle {\sqrt[{2}]{a}}.}  

La raíz de orden tres de  

a {\displaystyle a}  

, se llama raíz cúbica de  

a {\displaystyle a}  

y se escribe como  

a 3 . {\displaystyle {\sqrt[{3}]{a}}.}  

Las raíces de órdenes superiores se nombran usando números ordinales, por ejemplo raíz cuarta o raíz séptima.

La radicación es la operación inversa a la potenciación. s:
