Answer:

C. ED

Step-by-step explanation:

The center of the angle is the point E, so it would be written first.

The (2x,2y) column data is: A'=(-2,-6), B'=(-2,2), C'=(10,2) and D'=(10,-6). See the sketch of the (x,y) column and the (2x, 2y) column in the image 5.

The Cartesian graph presents x-axis (horizontal) and y-axis (vertical) that intercept in the origin (0,0). This type of graph is used to plot x and y coordinates.

The points, in the plane, are represented as (x,y).

Hence for your question:

A=(-1,-3) ⇒ -1 is x-coordinate and -3 is y-coordinate.

B=(-1,1) ⇒ -1 is x-coordinate and 1 is y-coordinate.

C=(5,1) ⇒ 5 is x-coordinate and 1 is y-coordinate.

D=(5,-3) ⇒ 5 is x-coordinate and -3 is y-coordinate.

For solving this question, you should plot the given points on a Cartesian graph.

      The result of this step you can see in the image 1.

         The result of this step you can see in the image 2.

         The result of this step you can see in the image 3. Now you see a rectangle.

       Thus, you should multiply x-coordinate and y-coordinate by 2.

       A=(-1,-3) ⇒ A'=(-2,-6)

       B=(-1,1)   ⇒ B'=(-2,2)

       C=(5,1)   ⇒ C'=(10,2)

       D=(5,-3) ⇒ D'=(10,-6)

       The result of this step you can see in the image 4.

         The result of this step you can see in the image 5. Now you see a new red rectangle with dimensions greater than the black rectangle plotted from (x,y) column.

Answer:

460

Step-by-step explanation:

i just did the question so yk

Answer: 460

Step-by-step explanation:

Hello!

Let's solve this question by using elimination.

5x + 10y = 7

4x + 8y = 3

Let us solve for "y" first by making our "x" variables cancel each other out.

4(5x + 10y = 7)

-5(4x + 8y = 3)

20x + 40y = 28

-20x -40y = -15

0 = 13

Since both the "x" and "y" variables were canceled out after trying to eliminate one of the variables, we can't find a solution since we now have no variables to solve for, therefore there is no solution.

Answer: No solutions

Answer:

As with any function, the domain of a quadratic function f(x) is the set of x -values for which the function is defined, and the range is the set of all the output values (values of f ). Quadratic functions generally have the whole real line as their domain: any x is a legitimate input. The vertex will be the minimum (lowest point) of the graph if and the maximum (highest point) of the graph if

Step-by-step explanation:

    We can look at the graph given to see the value of -3.

When h(x) = -3, it means that the y value is equal to -3. We see that, on the graph, when y = -3, x = -1.

Answer:

4 mins

Step-by-step explanation:

I guess not to sure ask teacher

Sam eats the melon in 0.2 minutes.

John eats the melon in 2.2 minutes.

x - y = 2 equation 1

x + y = 2.4 equation 2

Where:

x = minutes John eats the melon

y = minutes Sam eats the melon

Add equation 1 and equation 2 together

2x = 4.4

Divide both sides by 2

x = 2.2

Substitute for x in equation 1

2.2 - y = 2

y = 2.2  2

y = 0.2 minutes

Answer:

Step-by-step explanation:

We know if we multiply 6x2=12 and 6x5=30. After 6 you can not multiply anything else higher than that. For example 15x2=30 but 15 is not a GCF of 12 and 4x3=12 3 and 4 are not GCFs of 30. So 6 is the GCF of 12 and 30.

The value of c in cents when he bought 3 cakes for c cents and 2 loaves of bread for 2c - 11 cents each is 87 cents.

He buys 3 cakes that cost c cents each.

Therefore,

cost of the 3 cakes = 3c

2 loaves of bread that cost 2c - 11 cents each. Therefore,

cost of the two loaf of bread = 2(2c - 11) = 4c - 22

Hence, the total amount he spends can be represented as follows:

5.87 dollars = 587 cents

Therefore,

3c + 4c - 22  = 587

7c = 587 + 22

7c = 609

c = 609 / 7

c = 87

Answer:

Step-by-step explanation:

1) (y - 1)²

   1. y*y =y²

   2. 2(y)(-1)= -2y

   3 . (1)(1) = 1

(y-1)² = y² - 2y + 1

2) (6y + 3)²

    1. (6y)(6y) = 36y²

    2. (2)(6y)(3)=36y

    3. (3)(3)   = 9

(6y + 3)² = 36y² + 36y + 9

3) (4x - y)²

    1. (4x)(4x) = 16x²

    2. (2)(4x)(-y) = -8xy

    3. (y)(y) = y²

(4x -y)² = 16x² - 8xy + y²

4) (y - 12)²

 1.(y)(y) = y²

 2. (2)(y)(-12) = -24y

 3. (12)(12) = 144

(y - 12)² = y² - 24y + 144

V=1/3 πr²h

700 π=1/3 πr²×21

r²=100

r=√100=10 units

Answer:

r = 10

Step-by-step explanation:

Using the formula:

[tex]V = \pi r^{2} \frac{h}{3}[/tex]

We make r the subject to get:

[tex]r = \sqrt{3 \frac{V}{\pi h} }[/tex]

Now we substitute values given and simplify:

r = [tex]\sqrt{3 \frac{700\pi }{21\pi } }[/tex]

We can cancel out pi from top and bottom:

r = [tex]\sqrt{3 \frac{700 }{21 } }[/tex]

We can do 700÷21 = 33.3333333333

Now we have:

[tex]r = \sqrt{3 *33.3333333333}[/tex]
Simplify to get :

r ≈ 10

Step-by-step explanation:

[tex]10 + |10n + 6 | = 76 \\ \\ |10n + 6 | = 76 - 10 \\ |10n + 6 | = 66 \\ 10n + 6 = 66 \: \: \: \: \: or \: \: \: \: 10n + 6 = - 66 \\ 10n = 66 - 6 \: \: \: \: \: \: \: 10n = - 66 - 6 \\ 10n = 60 \: \: \: \: \: \: \: \: \: 10n = - 72 \\ n = 6 \: \: \: \: \: n = - 7.2[/tex]

Let's imagine all the tickets were for children.

The fees collected would've been 342 x 1.25 = $427.5

That is 1337 - 427.5 = $909.5 less than the actual fees.

Everytime we switch 1 children ticket to an adult ticket, the gap goes down 6.60 - 1.25 = 5.35

For example, if 341 tickets were children tickets, and 1 is adult, the gap go from 909.5 to 904.15.

We do this until the gap becomes 0... So, there are 909.5 : 5.35 = 170 adult tickets

And there are 342 - 170 = 172 children tickets


Recheck : 172 x 1.25 + 170 x 6.6 = 215 + 1122 = 1337.
