Answer:

(D)Prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals

Step-by-step explanation:

Let us verify the choosen option

In Quadrilateral ABCD with points A(-2,0), B(0,-2), C(-3,-5), D(-5,-3)

Using the distance formula

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$|AB|=\sqrt{(0-(-2))^2+(-2-0)^2}=\sqrt{8}=2\sqrt{2}\\|CD|=\sqrt{(-5+3))^2+(-3+5)^2}=\sqrt{8}=2\sqrt{2}\\|BC|=\sqrt{(-3-0))^2+(-5+2)^2}=\sqrt{18}=3\sqrt{2}\\|AD|=\sqrt{(-5+2)^2+(-3-0)^2}=\sqrt{18}=3\sqrt{2}\\$

Since |AB| is congruent to |CD| and |BC| is congruent to |AD|, we conclude that opposite sides are congruent.

Next, let us consider the slope.

Slope of |AB|= $\frac{-2-0}{0-(-2)} =\frac{-2}{2}=-1$

Slope of |BC| $=\frac{-5+2}{-3-0} =\frac{-3}{-3}=1$

Since the slopes of consecutive sides are opposite reciprocals, therefore ABCD is a rectangle.

<u>Option D is the correct option.</u>

Which values for h and k are used to write the function f(x) =

oksano4ka [1.4K]

Answer:

h = -6, k = -30.

Step-by-step explanation:

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

f(x) = x^2 + 12x + 6

f(x = (x + 6)^2 - 36 + 6

f(x) = (x + 6)^2 - 30

So comparing with the above general for:

h = -6 and k = -30.

If QR = 9 and ST = 13 calculate LM.

pickupchik [31]

Answer:

$\boxed{\sf LM = 11}$

Step-by-step explanation:

According to trapezoid mid-segment theorem:

$LM = \frac{QR+ST}{2}\\ Given \ that\ QR = 9, ST = 13$

$\sf LM = \frac{9+13}{2}$

LM = 22/2

LM = 11
