Answer:

The number of children tickets sold was 610.

Step-by-step explanation:

Let

x ----> the number of adults tickets sold

y ----> the number of children tickets sold

we know that

x+y=1710 -----> equation A

50x+25y=70250 ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (1100,610)

therefore

The number of children tickets sold was 610.

which equation is the direct variation equation if f(x) varies directly with x and f(x)=-9 when x = 3

fomenos

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we know that }
\begin{cases}
\stackrel{f(x)}{y}=-9\\
x=3
\end{cases}\quad -9=k3\implies \cfrac{-9}{3}=k\implies \boxed{-3=k}
\\\\\\
thus\qquad \qquad \stackrel{f(x)}{y}=-3x$
