Question

practice
identify the dependent variable and the independent variable in each situation.

1. the distance traveled, d, and the speed, s
2. the calories, c, in a snack and the amount of the snack, a
3. the amount of money you have spent, s, and how much money you have left, m
4. the number of apple slices remaining, r, and the number of apple slices eaten, e

solve equations

practice

1. find the pattern and then write a rule and an equation that represents the pattern. then complete the table.

Explanation:

An independent variable is the one you can change or control, and the dependent variable depends on the independent one.

1. Speed affects distance traveled, so speed is independent, distance is dependent.
2. The amount of snack controls calorie count, so amount is independent, calories are dependent.
3. Spent money affects leftover money, so spent money is independent, leftover is dependent.
4. Eaten slices affect remaining slices, so eaten slices are independent, remaining are dependent.

Answer:

1. Independent variable: speed ($s$), Dependent variable: distance traveled ($d$)
2. Independent variable: amount of the snack ($a$), Dependent variable: calories ($c$)
3. Independent variable: money spent ($s$), Dependent variable: money left ($m$)
4. Independent variable: apple slices eaten ($e$), Dependent variable: apple slices remaining ($r$)

Note: The "Solve Equations" practice question is incomplete (no table/pattern provided), so it cannot be addressed. Please share the full details of that question if you need help with it.
