Answer:

16

Step-by-step explanation:

Perfect square in the quadratic from ax² + bx + c

You know an equation is perfect when:

2√(ax²)√(c) = bx

Substitute x² for ax² and 8x for bx. Then isolate c by doing the reverse operations.

2√(ax²)√(c) = bx

2√(x²)√(c) = 8x

2x√c = 8x   Divide both sides by 2x

√c = 4    Square both sides to isolate c.

c = 16

The missing constant term is 16.

Check answer:

x² - 8x + 16

(x - 4)²

= (x - 4)(x - 4)

= x² - 4x - 4x + 16

= x² - 8x + 16

The system of equations represented by the graph is:

y = x - 6

y + x = -2

And the solution is (2, -4), then the correct option is the first one.

<h3>What system is represented by the graph?</h3>

On the graph, we can see a system of linear equations, we can see a line with a positive slope and a line with a negative slope.

The line with a positive slope intercepts the y-axis at y = -6, then that line is:

y = a*x - 6

with a > 0.

The other line passes through the y-axis at y = -2, then the linear equation is:

y = b*x - 2

Where b < 0.

Also, remember that the solution for the system of equations is the point where the two lines intersect, so we can see that the solution is at (2, -4)

The only option that meets all the criteria is the first option:

y = x - 6

x + y = -2

And the solution is (2, -4)
