Find the Domain 0.6x+0.3y=2.1

Problem

0.6*x+0.3*y=2.1

Solution

1. Identify the type of equation. This is a linear equation in two variables, x and y which represents a straight line in the Cartesian plane.

2. Determine the constraints on the independent variable x In a linear function of the form y=m*x+b there are no square roots of negative numbers, no logarithms of non-positive numbers, and no variables in the denominator.

3. Conclude that since the expression is a polynomial of degree 1, it is defined for all real numbers.

Final Answer

Domain: *(−∞,∞)
