Given f(x) = x^2 − 2x − 5.

Answer:

$(x - 1)^2 - 6$

Step-by-step explanation:

You need to know:

Vertex form = $a(x -h)^2 + k$

The vertex is at

(h, k)

Need to know about perfect squares

Need to know how to complete the square.

-----------------------------------------------------------------------------------------

To convert $x^2-2x-5$ you need to complete the square on the equation.

Complete the Square $x^2 - 2x -5$

$x^2 - 2x -5$

$(x^2 - 2x) -5$

Divide -2 by 2 and then square it.

$\frac{-2}{2} = -1$

$-1^2 = 1$

Add the one to the parentheses and subtract the one from the 5

$(x^2 - 2x +1) -5 -1$

Square $(x^2 - 2x +1)$

$(x-1)^2$

Now we have

$(x - 1)^2 -5 -1$

Next add -5 - 1 = -6

$(x - 1)^2 - 6$

Our quadratic is in vertex form now.

Vertex form = $a(x -h)^2 + k$

our equation = $(x - 1)^2 - 6$

Vertex = (1, -6)

Answer:

The net force of the brick is 0N and the brick doesn't move

Step-by-step explanation:

Both forces have the same amounts being applied to on the brick, so the forces will cancel each other out and have no effect on the brick, so the brick won't move.

Find the slope of line that is parallel to -2x=3y+5

In-s [12.5K]

Answer: m = $-\frac{2}{3}$

Step-by-step explanation:

Turn the equation into slope-intercept form: $-3y = 2x + 5$

Reduce: $y = -\frac{2}{3}x -\frac{5}{3}$

Your parallel slope is: $-\frac{2}{3}$
