The ski club wants to take in at least $100 in profit for the bus to Holiday Valley. Students pay $5 to ride the bus and chapero
laiz [17]

Answer:

x + y < 20

5x + 10y ≥ 100

Step-by-step explanation:

The ski club wants at least $100

Student pays $5

Chaperone pays $10

Maximum number of seats = 20

Assumption:

Assumed number of students = x

Assumed number of chaperone = y

Equation:

Maximum number of seats = 20

⇒ x + y < 20

The club wants $100

⇒ 5x + 10y ≥ 100

Which graphs below have a domain of all real numbers? Which have a range of all real numbers? Which are functions?
slava [35]

Answer:

Step-by-step explanation:

From the picture attached,

Graph (A)

Domain of the function : (-∞, ∞) or a set of real numbers

Range of the function : (-∞, ∞) or a set of real numbers

Graph (B),

Domain : (-∞, ∞) Or a set of real numbers

Range : (-∞, 6] Or x ≤ 6

Graph (C),

Domain : [-2, ∞) or x ≥ -2

Range : (-∞, ∞) Or a set of real numbers

Therefore, Graphs (A), (B) have the domain of all real numbers and Graph (C) has the range of all real numbers.

Since all the parabolas are not the functions,

Therefore, Graph (C) is not a function. Graphs (A) and (B) are the functions.
