Question

How do i use a graphing calculator to solve the system.

Answer 1

Given:

`\begin{gathered} 0.4x\text{ + }√(2)y\text{ = 1} \\ √(5)\text{ x + 0.8y = 1} \end{gathered}`

Using a graphing calculator, we have the graph shown below:

The point of intersection of the equations represents the solution to the system.

Hence, the solution to the system is:

x = 0.216

y = 0.646
