Step-by-step explanation:

The complete question is contained in the image.

The distance between points [tex]A(x_1,y_1)[/tex] and [tex]B(x_2,y_2)[/tex] in the coordinate plane is given as:

[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Point D is at (7, 0) and E at (0, -2) hence the distance between the two points is:

[tex]|DE|=\sqrt{(0-7)^2+(-2-0)^2}=\sqrt{49+4}=\sqrt{53}=7.28[/tex]

Point R is at (-7, -7) and S at (3, -3) hence the distance between the two points is:

[tex]|RS|=\sqrt{(3-(-7))^2+(-3-(-7))^2}=\sqrt{100+16}=\sqrt{116}=10.77[/tex]

Since |RS| ≠ |DE|, therefore they are not congruent

Step-by-step explanation:

K = 13 J = ?

2J - 7 = 13

2J = 20

J = 10

Answer: 10

Step-by-step explanation:

[tex]\bf Step-by-step~explanation:[/tex]

We are given that BA is perpendicular to BD, so that must mean that m∠ABD is a right angle, or 90º. This means: (8x - 10) + (4x + 52) = 90º, since both of the angles add up to become a right angle. We have to solve for x in order to find m∠CBD.

PART 1

[tex]\bf Step~1:[/tex]

Equation: (8x - 10) + (4x + 52) = 90

Let's add the like values together first.

[tex]\bf 8x+4x=12x\\-10+52 = 42[/tex]

[tex]\bf 12x+42=90[/tex]

[tex]\bf Step~2:[/tex]

Let's subtract 42 from both sides of the equation to isolate the variable we are solving for, x. Our goal is to isolate it completely to get a value that is equal to x.

[tex]\bf12x+42(-42)=90(=42)\\12x=48[/tex]

[tex]\bf Step~3:[/tex]

Divide both sides by 12 to get our final answer for x.

[tex]\bf\frac{12x}{12} =x\\\\\frac{48}{12}= 4\\\\x=4[/tex]

PART 2

Now that we have x, we simply plug it into our equation for m∠CBD.

[tex]\bf Step~1:[/tex]

[tex]\bf4x+52\\4(4)+52[/tex]

[tex]\bf Step~2:[/tex]

Multiply 4 and add 52.

[tex]\bf 4*4=16\\16+52=68[/tex]

[tex]\large\boxed{\bf Our~final~answer: mCBD=68}[/tex]

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(3, 11) and B(7,3)

The midpoint is

[tex]M = ( \frac{3 + 7}{2} \: , \: \frac{11 + 3}{2} ) \\ = ( \frac{10}{2} \: , \: \frac{14}{2} )[/tex]

We have the final answer as

Answer: MP=(1,1)

Step-by-step explanation:

[tex]MP= (\frac{x_1+x_2}{2})(\frac{y_1+y_2}{2})[/tex]

[tex]MP= (\frac{-2+4}{2})(\frac{-3+5}{2})[/tex] -2+4=2  -3+5=2

[tex]MP= (\frac{2}{2})(\frac{2}{2})[/tex] 2/2=1

[tex]MP= (1,1)[/tex]    

Answer:

(1,1)

Step-by-step explanation:

70 Degrees

Step-by-step explanation:

I can only see on your picture that the answer choices are 70 Degrees and 40 Degrees.

The angle "w" is almost a right angle which is 90 Degrees.

Out of the two choices 70 Degrees is the closest number to 90 Degrees.

So that's how the answer is 70 Degrees.

Answer: C

Step-by-step explanation:

Answer:

its B just took test

Step-by-step explanation:

Answer:

[C] -1

Explanation:

3 - 2x = 5

Subtract 3 from both sides

3 - 2x - 3 = 5 - 3

Simplify

-2x = 2

Divide both sides by -2

-2x / -2 = 2 / -2

x = -1

The scale factor of the drawing of the house given the scale of the drawing is 1cm : 0.29m.

A scale drawing is a smaller image of a larger image or object. The scale drawing is usually reduced at a constant dimension.

The scale factor is the ratio of the dimension of the scale drawing to the original object. The scale factor is the measurement used to convert the larger image into a smaller version of the original object.

The scale factor is usually written in this format - 1, a colon (:), then the matching length on the original image. e.g. 1 : 10

The scale factor of the drawing = original dimensions/dimensions of the scale drawing

2 / 7 = 0.29

The complete question is given below.

Answer:

[tex]k=13\text{ or } k=-7[/tex]

Step-by-step explanation:

So we have the equation:

[tex]|-3+k|=10[/tex]

Definition of Absolute Value:

[tex]-3+k=10\text{ or } -3+k=-10[/tex]

Add 3 to both sides for both equations:

[tex]k=13\text{ or } k=-7[/tex]

And we're done!

Answer:

K=13

Step-by-step explanation:

|-3+k|=10 this is an equation with absolute  value

add 3 on both sides

k=13

= 63÷ 9

= 7

So the correct answer option is b 7.

Answer:

$57

Step-by-step explanation:

1h = $39

so the first hour costs $39

2.5h -1h =1.5h=90mins

0.20x90=18

so 1h30mins after the initial 1h cost $18

so all together it costs $18+$39= $57

Given that:

James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3 .

To find:

The equation that can be used to solve for zach's age.

Solution:

Let the age of zach be Z.

Zach added 8 to his age = Z+8

And multiplied this sum by 3 = 3(Z+8)

James is 6 times older than his friend Zach = 6Z

Now,

[tex]6Z=3(Z+8)[/tex]

[tex]6Z-3Z=24[/tex]

[tex]3Z=24[/tex]

Divide both sides by 3.

[tex]Z=8[/tex]

Therefore, the required equation is [tex]6Z=3(Z+8)[/tex] is age of zach is 8 years.
