\text{Consider the function}\\
\\
f(x)=\sqrt{7+x}\\
\\
\text{Since it is a radical function, so the term inside the radical must be positive}\\
\\
\text{so to find the domain of the function, we will solve the inequality,}\\
\\
7+x\geq 0\\
\\
\Rightarrow x\geq -7\\
\\
\text{hence the domain of the function is all real number greater than }x=-7.\\
\\
\text{or the domain of the function is:}\\
\\
x\geq -7

Natalija [7]

Answer:

The Answer is that Senior Citizen Tickets cost: $4 and Child tickets cost: $7.

Step-by-step explanation:

Let s = the cost of senior citizen tickets

Let c = the cost of child tickets

The number of tickets sold for each type added together equals the sales for each day. Equations below:

Day 1

3s + 9c = $75

Solve for s:

3s = 75 - 9c

s = 25 - 3c

Day 2

8s + 5c = $67

By substitution:

8(25 - 3c) + 5c = 67

200 - 24c + 5c = 67

-19c = -133

c = -133 / -19 = $7 cost for child tickets.

Solve for s:

s = 25 - 3c

s = 25 - 3(7)

s = 25 - 21 = $4 cost for senior citizen tickets.

Proofs:

Day 1

3s + 9c = $75

3(4) + 9(7) = 75

12 + 63 = 75

75 = 75

Day 2

8s + 5c = $67

8(4) + 5(7) = 67

32 + 35 = 67

67 = 67
