You have point D (4, 2) that is rotated 180 degrees about the origin, what are the coordinates of D'? Type answer as an ordered pair: (x, y)

Answer:

y=90⁰

Step-by-step explanation:

● 180⁰-110⁰=70⁰ (lines on a straight line)

70⁰+70⁰+x+x= 180⁰( sum of a triangle=180⁰)

2x=40⁰

x=20⁰

● 70⁰+20⁰+y=180⁰(sum of a triangle =180⁰)

y=180⁰-90⁰

y=90⁰

Angles of the triangle:

angle1 = 70°

angle2 = (x + x)°

angle3 = (180 - 110)°

By angle sum property of a triangle,

angle1 + angle2 + angle3 = 180°

Therefore,

70 + (x + x) + (180 - 110) = 180

70 + 2x + 70 = 180

140 + 2x = 180

2x = 180 - 140

2x = 40

x = 40/2

x = 20

Hence, x = 20°

Answer:1111

Step-by-step explanation:jejejeje

Answer:

see explanation

Step-by-step explanation:

CY = CB + BY

     = 6b + 5a - b

     = 5a + 5b

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

CX = CA + AX

     = CA + [tex]\frac{1}{3}[/tex] AB , find AB

AB = AC + CB

     = - 3a + 6b

     = 6b - 3a

Thus

CX = CA  + [tex]\frac{1}{3}[/tex] AB

      = 3a + [tex]\frac{1}{3}[/tex](6b - 3a)

      = 3a + 2b - a

      = 2a + 2b

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

and

[tex]\frac{2}{5}[/tex] CY

= [tex]\frac{2}{5}[/tex] (5a + 5b)

= 2a + 2b = CX

Hence CX = [tex]\frac{2}{5}[/tex] CY ⇒ Proven

Answer:

-25.

Step-by-step explanation:

What is the difference of outputs for any two inputs that are one value apart?

If you look at the column of "x" [input], you will see that they are 1 unit apart. You can thus look at the corresponding values of "f(x)" [output] and determine their difference. Checking all of those, gives us the difference (same for all).

Output 2 - Output 1:

Output 3 - Output 2:

Output 4 - Output 3:

Output 5 - Output 4:

So the difference of outputs for any two inputs one value apart are

Well, being a rudimentary rule of math, I'm going to work this out in a mental math manner for you to help you understand how it works.

Step 1 - Write it out laterally

    1288

    x  33

Step 2 - Multiply 3 across; make sure to carry

    1288

    x  33

    3864

Step 3 - Add a zero to the end on the next line then repeat with the next 3 which is in the 10s place preparing it into an addition problem

    1288

    x  33

    3864

+ 38640

Step 4 - Add them together

    1288

    x  33

    3864

+ 38640

  42504

Hope this helps

Answer:

Both of these statements are correct.

Step-by-step explanation:

Adjacent means next to each other, vertical angles are like angles 2 and 5, where they are right across from each other.

Answer:    -3(x-10)<30,X there you go BOM

Step-by-step explanation:

Format:

{Expression} = {Rewritten} = {Value}

Answer:

3/8 * 24 = 72/8 = 9

5/9 * 18 = 90/9 = 10

11/12 * 36 = 396/12 = 33

Answer:

Step-by-step explanation:

You need to set up a proportion.

10 pounds of potatoes/15 pounds of mashed potatoes

Before going on notice that the potatoes are on the top part of the fraction and the mashed potatoes are on the bottom. The right hand side of the proportion must be the same.

10 pounds potatoes/15 pounds mashed = x pounds / 50 pounds mashed.

The raw potatoes are on the top, The mashed is on the bottom. It's always like that.

The second step is to cross multiply.

10 / 15 = x / 50          Cross miultiply

10*50 = 15 * x            Combine the left

500 = 15x                  Divide by 15

500/15 = x

x = 33.33

Answer:

33.33

Answer: Alex is making $ 13.58 after his decrease in pay.

Step-by-step explanation:

Given: Hourly pay for Alex before decrease in pay = $14

His salary decreased by 3%.

New hourly pay = Previous hourly pay - 3% of ( Previous hourly pay )

= $(14-0.03 (14))

= $ (14(1-0.03))

= $ (14(0.97))

=$ 13.58

Hence, Alex is making $ 13.58 after his decrease in pay.
