Step-by-step explanation:

Triangle DCB is similar to Triangle ECA by AAA.

Since EA and DB are parallel lines, that makes Angle CDB = Angle CEA and Angle CBD = Angle CAE because they are corresponding angles.

Since the two triangles are parallel, we can set up a ratio.

[tex]\frac{CD}{CE} = \frac{CB}{CA}[/tex]

Now we plug in the numbers given.

[tex]\frac{6}{8} = \frac{9}{CA}[/tex]

Now we can cross multiply

6CA = 72

Therefore, CA = 12.

AB = CA - CB

So AB = 12 - 9

AB = 3

x = 140/8 = 17.5 cm

Considering the median, the missing value of the data-set is of 31.

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.

In this problem, since the set has even cardinality, the median is the mean of the middle elements, which are 23 and x. Since it is of 27, we have that:

(23 + x)/2 = 27

23 + x = 54

x = 31

Hence, the missing value of the data-set is of 31.

Answer: y = 9x - 14

Step-by-step explanation:

The equation of a line is y = mx + b

We know the slope is 9 so so far the equation we have is y = 9x + b.

Since we know (1,-5) is a point on the line, we can plug in the x and y values into the equation and we get:

-5 = 1*9 + b

-5 = 9 + b

b = -14.

Therefore, the equation of the line is y = 9x - 14

Hello.

Here we have a point that the line passes through: (1, -5)

We also have the line's slope: 9

Now, we have enough information to write the line's equation in Point-Slope Form:

[tex]\mathrm{y-y1=m(x-x1)}[/tex]

Plug in the values and solve:

[tex]\mathrm{y-(-5)=9(x-1)}[/tex]

[tex]\mathrm{y+5+9(x-1)}[/tex]

[tex]\mathrm{y+5=9x-9}[/tex]

[tex]\mathrm{y=9x-9-5}[/tex]

[tex]\mathrm{y=9x-14}[/tex]

Therefore, the answer is

[tex]\mathrm{y=9x-14}[/tex]

Answer:

B

Step-by-step explanation:

As you can see if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.

The pair of functions that are inverses of each other will be f(x) = 10x - 5. g(x) = x - 5/10. so option B is correct.

Function is a type of relation, or rule, that maps one input to specific single output. Inverse means that the function is reversed from the original function, f(x).

A:  The original function, f(x) = x/8 + 3. g(x) = 8x - 3. they are not inverse functions.

B:  The original function, f(x) = 10x - 5. g(x) = x - 5/10. they are inverse functions.

C:  The original function, f(x) = 4/x - 3. g(x) = 1/x + 3/ 4, they are not inverse functions.

Hence, the pair of functions that are inverses of each other will be f(x) = 10x - 5. g(x) = x - 5/10. so option B is correct.

Label the points A,B,C

Let's find the distance from A to B, aka find the length of segment AB.

We use the distance formula.

[tex]A = (x_1,y_1) = (1,2) \text{ and } B = (x_2, y_2) = (4,5)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-4)^2 + (2-5)^2}\\\\d = \sqrt{(-3)^2 + (-3)^2}\\\\d = \sqrt{9 + 9}\\\\d = \sqrt{18}\\\\d = \sqrt{9*2}\\\\d = \sqrt{9}*\sqrt{2}\\\\d = 3\sqrt{2}\\\\[/tex]

Segment AB is exactly [tex]3\sqrt{2}[/tex] units long.

Now let's find the distance from B to C

[tex]B = (x_1,y_1) = (4,5) \text{ and } C = (x_2, y_2) = (8,9)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(4-8)^2 + (5-9)^2}\\\\d = \sqrt{(-4)^2 + (-4)^2}\\\\d = \sqrt{16 + 16}\\\\d = \sqrt{32}\\\\d = \sqrt{16*2}\\\\d = \sqrt{16}*\sqrt{2}\\\\d = 4\sqrt{2}\\\\[/tex]

Segment BC is exactly [tex]4\sqrt{2}[/tex] units long.

Adding these segments gives

[tex]AB+BC = 3\sqrt{2}+4\sqrt{2} = 7\sqrt{2}[/tex]

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

Now if A,B,C are collinear then AB+BC should get the length of AC.

AB+BC = AC

Let's calculate the distance from A to C

[tex]A = (x_1,y_1) = (1,2) \text{ and } C = (x_2, y_2) = (8,9)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-8)^2 + (2-9)^2}\\\\d = \sqrt{(-7)^2 + (-7)^2}\\\\d = \sqrt{49 + 49}\\\\d = \sqrt{98}\\\\d = \sqrt{49*2}\\\\d = \sqrt{49}*\sqrt{2}\\\\d = 7\sqrt{2}\\\\[/tex]

AC is exactly [tex]7\sqrt{2}[/tex] units long.

Therefore, we've shown that AB+BC = AC is a true equation.

This proves that A,B,C are collinear.
