Chapter 12: Q.12.12 (page 714)

Due to erosion, a river shoreline is losing several thousand pounds of soil each year. A linear equation that expresses the total amount of soil lost per year is y=12,000x

What are the independent and dependent variables?

Short Answer

Expert verified

The dependent variable is the amount of soil lost in the pound that is y and the independent variable is time that is year in the question x variable.

Step by step solution

01

Given information

Given in the question is a linear equationy=12,000x.

02

Solution

The independent variable is the variable the researcher operates or changes, and is guessed to contain a direct impact on the dependent variable.

The dependent variable means the variable being experimented and estimated in an investigation, and is 'dependent' on the independent variable.

The statement here is a river shoreline is losing several thousand pounds of soil each year

Here the dependent variable y is the amount of soil lost in the pound and the independent variable x is the time (year)
