for the inverse variation equation xy = k, what is the value of x when y = 4 and k = 7?\n$\frac{4}{7}$\n$\frac{7}{4}$\n3\n28

Answer

Explanation:

Step1: Sustituir valores en la ecuación

Dada la ecuación $xy = k$, sustituimos $y = 4$ y $k = 7$. Obtenemos $x\times4=7$.

Step2: Resolver para $x$

Dividimos ambos lados de la ecuación $4x = 7$ por 4. Entonces $x=\frac{7}{4}$.

Answer:

B. $\frac{7}{4}$
