The last graph.

<em>Explanation:
</em><em /><em />Since you are looking for a solution you need to look at the place where both lines connect, in this case, we are looking for the coordinate ( 2, -1 ) 
2 being the x-axis and -1 being the y-axis
The last graph is the only one that shows that the two lines touch at the coordinate ( 2, -1 )

The solution to a system of equations is the point on a graph where the two lines intersect. The graph where the point of intersection is (2, -1) is the last graph. The last graph is the correct answer.

<h2>Answer:</h2>

The answer is 16.

<h2>Step-by-step explanation:</h2>

Since the 8x is positive, the equation  must have y as a positive number.

Let's see this!

An easy way to complete the square if you have the constants for x2 and

But not the non-variable number is to divide the x constant, and then square it.

Example:

\frac{8x}{2} \\\\4^2=16\\

The last number must be 16. Let's check it.

(x+4)^2=x^2+8x+16

Which ordered pair makes both inequalities true y x 1 YX?
denis-greek [22]

The ordered pair which makes both inequalities true is (-2, 2).

It is given that inequalities are

y < -x + 1 and y > x

For  y < -x + 1

Substituting every ordered pair,

1) (-3, 5)

⇒ 5 < - (-3) + 1

⇒ 5 < 3 + 1

⇒ 5 < 4 is false

2) (-2, 2)

⇒ 2 < -(-2) + 1

⇒ 2 < 2 + 1

⇒ 2 < 3 is true

3) (-1, -3)

⇒ -3 < - (-1) + 1

⇒ -3 < 1 + 1

⇒ -3 < 2 is true

4) (0, -1)

⇒ -1 < -0 + 1

⇒ -1 < 1 is true

Now , for  y > x

1) (-3, 5)

⇒ 5 > -3 is true

2) (-2, 2)

⇒ 2 > -2 is true

3) (-1, -3)

⇒ -3 > -1 is false

4) (0, -1)

⇒ -1 > 0 is false

Therefore ,the ordered pair which makes both inequalities true is (-2, 2).
