Answer:

3x - 2

Step-by-step explanation:

$4x + 2 - \frac{ {x}^{2} + x - 12}{x - 3} \\ \\ = 4x + 2 - \frac{ {x}^{2} + 4x - 3x- 12}{x - 3} \\ \\ = 4x + 2 - \frac{ {x}(x + 4) - 3(x + 4)}{x - 3} \\ \\ = 4x + 2 - \frac{ (x + 4) \cancel{(x- 3)}}{\cancel{(x- 3)}} \\ \\ = 4x + 2 - (x + 4) \\ \\ = 4x + 2 - x - 4 \\ \\ = 4x - x + 2 - 4 \\ \\ = 3x - 2$

Find the inequality for this graph

Arada [10]

ANSWER

$y \geqslant - 2x - 5$

EXPLANATION

First we need to find the equation of the boundary line which passes through (-1,-3) with a y-intercept of -5.

The slope of this line is

$m = \frac{ -5 - - 3}{0 - - 1} = - 2$

The equation of this line is

$y = - 2x - 5$

Since the boundary line is solid and the upper half plane is shaded the required inequality is

$y \geqslant - 2x - 5$
