Write an equation in standard form for a line that passes through (2,2) and (0, -3).
Alecsey [184]
First find the slope:
(-3-2)/(0-2)=-5/-2=5/2

So then y=5/2x+b

When x=0, then the y-coordinate with that is the y-intercept.

So the answer is y=5/2x-3.

SI UN NUMERO SE MULTIPLICA POR 7, EL RESULTADO ES IGUAL AL NUMERO AUMENTADO EN 24. ¿ CUAL ES EL NUMERO? 7 . X : X + 24
andre [41]

Answer: El número es 4.

Step-by-step explanation:

Sea X un número.

Acá tenemos:

"Si un número se multiplica por 7"

Esto se escribe como 7*X

"... El resultado es igual al número aumentado en 24"

Esto lo podemos escribir como:

7*X = X + 24

Ahora debemos resolver esta ecuación para X.

7*X = X + 24

Primero, debemos llevar todos los términos con X al mismo lado de la ecuación, para hacer esto, podemos restar X en ambos lados:

7*X - X = (X + 24) - X

6*X = 24

Ahora debemos dividir ambos lados por 6.

6*X/6 = 24/6

X = 4

El número es 4.
