1 answer:

4 0

Here is your great answer Simplifying
4x2y + 12xy2 + 9y3

Reorder the terms:
12xy2 + 4x2y + 9y3

Factor out the Greatest Common Factor (GCF), 'y'.
y(12xy + 4x2 + 9y2)

Factor a trinomial.
y((2x + 3y)(2x + 3y))

Final result:
y(2x + 3y)(2x + 3y)

Answer:

$(x,y) = (-1,1)$

Step-by-step explanation:

Given

$y>-2x - 1$

$y>x + 2$

Required

Solve graphically

See attachment for graph;

The black shade represents $y>-2x - 1$

While the green, represents $y>x + 2$

Next, determine the intersection points between the two lines

From the attached graph, we have:

$(x,y) = (-1,1)$

<em>Hence, the solution is:</em> $(-1,1)$
