10. A movie theater advertises that a family of two adults, one student, and one child between the ages of 3
BlackZzzverrR [31]

Answer:

Students ticket = $4

Child ticket = $1

Adult ticket = $5

Step-by-step explanation:

Let the price of the student ticket be $x and the price of a child ticket be $y.  An adult ticket costs as much as the combined cost of a student ticket and a child ticket, so the price of one adult ticket is $(x+y).

1. A movie theater advertises that a family of two adults, one student, and one child between the ages of 3 and 8 can attend a movie for $15. Then

2(x+y)+x+y=15

2. If you purchase 1 adult ticket, 4 student tickets, and 2 child tickets for $23, then

(x+y)+4x+2y=23

Now, solve the system of two equations:

\left\{\begin{array}{l}2(x+y)+x+y=15\\ \\(x+y)+4x+2y=23\end{array}\right.\Rightarrow \left\{\begin{array}{l}3(x+y)=15\\ \\5x+3y=23\end{array}\right.\\ \\\left\{\begin{array}{l}x+y=5\\ \\5x+3y=23\end{array}\right.\\ \\\left\{\begin{array}{l}y=5-x\\ \\5x+3(5-x)=23\end{array}\right.

Solve the last equation

5x+15-3x=23\\ \\2x=23-15\\ \\2x=8\\ \\x=4\\ \\y=5-x=5-4=1

Students ticket = $4

Child ticket = $1

Adult ticket = $5

If (x)=-2377 +3 and V(x)= x, what is the range of (LOV)(x)?​
kipiarov [429]

L(x)=-2377+3\Longrightarrow L(x)=-2374 \\V(x)=x

Both of the functions are linear. L(x) is constant.

However we are required to determine the range of (L\circ V)(x)

(L\circ V)(x)=L(V(x))=L(x)=-2374

So the only possible solution that such notation gives is -2374 so therefore the answer in terms of range is x\in\{-2374\}

Hope this helps.
