What is the solution to the system of equations graphed below?
Nana76 [90]

Answer:  (2, -3)

Step-by-step explanation:

Look at the point where the two graphed lines cross.  

The first number in the solution is the x-value,  that is how far to the left or right you count from the center O.  2 to the right +2

The second number in the solution is the y-value, that is how fat up or down you count from the center O.   3 down is -3

When you have those two values, you express them as the "coordinates" of that point. in this case  (2, -3)

Draw the region that satisfies all three of the inequalities; <br>x &lt; 3, y &gt; 2, y &lt; 2x+3​
FrozenT [24]

Check the picture below.

the line you drew for y = 2x +3 is correct, now recall that the line for x = 3 is just a vertical line, in red, and that y = 2 is just a horizontal line, in green.

now all lines are solid because all are using ⩽ or ⩾, meaning the borderline is included, and you can do a "true" "false" region check if you wish, but less than 3 is to the left of the red one, greater than 2 is above the green one and less than 2x + 3 is just to its left.

3x ^2 - 9 x y ^2+ 12 X ^3Y^2​
shepuryov [24]

\huge \boxed{\mathfrak{Question} \downarrow}

3 x ^ { 2 } y - 9 x y ^ { 2 } + 12 x ^ { 3 } y ^ { 2 }

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

3 x ^ { 2 } y - 9 x y ^ { 2 } + 12 x ^ { 3 } y ^ { 2 }

Factor out 3.

3\left(x^{2}y-3xy^{2}+4x^{3}y^{2}\right)

Consider x^{2}y-3xy^{2}+4x^{3}y^{2}. Factor out xy.

xy\left(x-3y+4x^{2}y\right)

Rewrite the complete factored expression.

\boxed{ \boxed{ \bf \: 3xy\left(x-3y+4x^{2}y\right) }}
