Chapter 4: Q 308 (page 473)

In the following exercises, solve each system by graphing.
$\{\begin{cases} 2 x + 4 y > 4 \\ y \leq - \frac{1}{2} x - 2 \end{cases}$

Short Answer

Expert verified

The equations have no solution.

Step by step solution

Given information.

Given system of equation

$\{\begin{cases} 2 x + 4 y > 4 \\ y \leq - \frac{1}{2} x - 2 \end{cases}$

Graph the system of equations

The system of equations $2 x + 4 y = 4$ has intercept $x = 2, y = 1$ .The boundary is solid. Origin does not lies within as putting $(0, 0) 0 \geq 4$

which holds false.

Calculating for second equation

For $y = - \frac{1}{2} x - 2$ ,

the intercepts are $x = - 4, y = - 2$ and testing the point $(0, 0)$ , we get

$0 \leq - 2$ ,

which is false hence, the origin is not contained in it.
