The cost to rent a moving truck is a flat fee of $25 plus $0.60 per mile. The equation c = 25 + 0.6m models the cost, c, in dollars for the number of miles, m, traveled in the truck.

Question

Identify the independent and dependent variables.

The
is the independent variable.

The
is the dependent variable.

Answer 1

In the equation \( c = 25 + 0.6m \) that models the cost to rent a moving truck:

- The independent variable is \( m \), which represents the number of miles traveled.
- The dependent variable is \( c \), which represents the total cost in dollars.

Therefore,

The **number of miles traveled (m)** is the independent variable.

The **cost (c)** is the dependent variable.

Answer 2

A graph where the horizontal axis shows time (t), numbered 1 to 4, and the vertical axis shows height (h) numbered 10 to 60. Solid circles appear at point (0, 48), point (1, 64), point (3, 0). A solid curved line connects all 3 points.
Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.

What is the domain?

{t| 0 ≤ t ≤ 3}
{t| 0 ≤ t ≤ 48}
{t| 0 ≤ t ≤ 64}
{t| all real numbers}
