Question

V varies inversely with T and V = 14 when T = 7. Which equation shows this relationship?

A. V = 2/T
B. V = 98/T
C. V = 2T
D. V = 98T

Is it B?

If my answer is correct, then please say that I'm correct. If I am not correct, tell me that it is so and explain. Thank you!

Answer 1

what did you get for the constant of variation?

Answer 2

98 = TV.. correct?

Answer 3

@jdoe0001 correct?

Answer 4

yes

Answer 5

so B is correct?

Answer 6

\(\bf \begin{array}{llll}
\textit{something }&\textit{varies inversely to }&\textit{something else}\\ \quad \\
\textit{something }&=\cfrac{(\textit{some value })}{\textit{something else}}\\ \quad \\
y&=\cfrac{(n)}{x}
\end{array}\\ \quad \\

v=14\qquad t=7\qquad \implies v=\cfrac{n}{t}\implies 14=\cfrac{n}{7}\implies 98=n\\ \quad \\
v=\cfrac{n}{t}\implies v=\cfrac{98}{t}\quad \checkmark\)
