Chapter 4: Q 311 (page 473)

In the following exercises, solve each system by graphing.
$\{\begin{cases} - 3 x + 6 y \geq 12 \\ 4 y \leq 2 x - 4 \end{cases}$

Short Answer

Expert verified

The equations have no solution.

Step by step solution

Given information.

Given system of equation,

$\{\begin{cases} - 3 x + 6 y \geq 12 \\ 4 y \leq 2 x - 4 \end{cases}$

Graph the system of equations

The system of equation $- 3 x + 6 y = 12$

has intercept $x = - 4, y = 2$ . The boundary is solid. Origin does not lies within as putting

$(0, 0) 0 \geq 12$

which holds false.

Calculating for second equation

For $4 y = 2 x - 4$ ,

the intercepts are $x = 2, y = - 1$ and testing the point ,

we get

$0 \leq - 4$ ,

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

Plotting the graph.
