Answer:

ABCD is a RHOMBUS or a SQUARE.

Step-by-step explanation:

The coordinates are A(-6, 6), B(-2, 8), C(0, 4), and D(-4, 2).

By DISTANCE FORMULA:

The length of the segment with coordinates X(a,b) and Y(c,d) is given as:

$XY = \sqrt{(c-a)^2 + (d-b)^2}$

Now, similarly, the lengths of the segments are:

$AB = \sqrt{(-2 -(-6))^2 + (8-6)^2}$

$=\sqrt{(4)^2 + (2)^2} = \sqrt{16 + 4} = \sqrt{20}$

⇒ The length of the segment AB = √ 20 units

$BC = \sqrt{(0 -(-2))^2 + (4-8)^2}$

$=\sqrt{(2)^2 + (-4)^2} = \sqrt{4 + 16} = \sqrt{20}$

⇒ The length of the segment BC = √ 20 units

$CD = \sqrt{(0 -(-4))^2 + (2-4)^2}$

$=\sqrt{(4)^2 + (-2)^2} = \sqrt{16 + 4} = \sqrt{20}$

⇒ The length of the segment CD= √ 20 units

$AD = \sqrt{(-6 -(-4))^2 + (6-2)^2}$

$=\sqrt{(-2)^2 + (4)^2} = \sqrt{4 + 16} = \sqrt{20}$

⇒ The length of the segment AD = √ 20 units

$AC = \sqrt{(0 -(-6))^2 + (4-6)^2}$

$=\sqrt{(6)^2 + (-2)^2} = \sqrt{36 + 4} = \sqrt{40}$

⇒ The length of the diagonal AC = √ 40 units

$BD = \sqrt{(-2 +4)^2 + (8-2)^2}$

$=\sqrt{(2)^2 + (6)^2} = \sqrt{36 + 4} = \sqrt{40}$

⇒ The length of the diagonal BD = √ 40 units

Since, here the length of all segments is √ 20 units.

⇒AB = BC = CD = AD = √ 20 units

and Diagonal AC = BD

⇒ ABCD is a RHOMBUS or SQUARE.

X+4+3x Equivalent Expressions

melamori03 [73]

If you want to simplify the expression, combine like terms

x and 3x go together, so they make 4x.

and 4 is just 4

So, the answer is

4x + 4

Which equation can be used to solve 3/5 divided by 7/10

Jlenok [28]

Answer:

35/50

Step-by-step explanation:

Here we will show you how to calculate 3/5 divided by 7/10. We will give you the answer in fraction form and in decimal form.

Here is 3/5 divided by 7/10 displayed

3/5 ÷ 7/10

The numbers in 3/5 divided by 7/10 are labeled below:

3 = dividend numerator

5 = dividend denominator

7 = divisor numerator

10 = divisor denominator

To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.

Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:

3 x 10/5 x 7 = 30/35

Thus, the answer to 3/5 divided by 7/10 in fraction form is:

30/50

Use the given parent function f(x)=|x| to graph g(x)=|x+2|-4. use the ray tool and select two points to graph each ray.

marin [14]

Shown in the attached figure

<h2>Explanation:</h2>

The absolute value function is a function that takes the shape of a V. The pattern of the absolute value function is:

$f(x)=\mid x \mid$

So we need to use this function in order to obtain:

$g(x)=\mid x+2 \mid -4$

Recall that to translate a function vertically, we use the following rule:

$g(x)=f(x)+k \\ \\ \bullet \ If \ k>0 \ the \ graph \ of \ f(x) \ is \ translated \ k \ units \ up \\ \\ \bullet \ If \ k$

And to translate a function horizontally, we use the following rule:

$g(x)=f(x+c) \\ \\ \bullet \ If \ c>0 \ the \ graph \ of \ f(x) \ is \ translated \ c \ units \ to \ the \ left \\ \\ \bullet \ If \ c$

Since:

$c=2>0 \ and \ k=-4$

Then:

<em>g(x) is the translation of f(x) 2 units to the left and 4 units down</em>
