Answer:

The answer is A. 2/3 =5/8

Step-by-step explanation:

The proportion that could be used to determine if the figures represent a dilation is 2/3= 5/8. Option A

Dilation is the process of increasing the size of the object without changing its shape and this is with a defined scale factor.

To determine if the figures represent a dilation, we need to compare the ratios of corresponding sides.

The correct proportion to use is the ratio of corresponding side lengths.

Then, we have that the figure;

2/3=5/8

This means that the ratio of corresponding side lengths in the figures is the same, indicating a dilation.

If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The central angle is double the angle at the periphery that was subtended by the same chords.

Both the extreme points of the chords are connected to the circle. Then the two triangles are formed whose two sides are the radius of the circle that is congruent to each other. Then the triangle will be an isosceles triangle.

And the chord length is also congruent. Then the triangles are congruent to each other by SSS postulates.

If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.

The required coordinate of the point N is (-5, -1). Option b is correct.

Given that,
Segment MN is drawn in the coordinate plane. Point M has coordinates (13,9) and the midpoint of MN is the point (4.4). What are the coordinates of point N to be determined.

Coordinate, is represented as the values on the x - axis and y - axis of the graph

Let the coordinate of point N is (x, y).
Here, point M has coordinates (13,9) and the midpoint of MN is the point (4.4).

The Coordinate of the midpoint is given as,
(4 = (x + 13)/2, 4 = (y + 9 )/2)
(x = 8 - 13, y = 8 - 9)
(x = -5 , y = -1 )
Coordinate of point N is (x, y) = (-5, -1)

Thus, the required coordinate of the point N is (-5, -1).

Answer:

1/9

Step-by-step explanation:

I'm assuming the equation you mean is y = (x/9)  -- if so, parentheses aren't really required.

The equation for the constant of proportionality is y=kx. So, we will want to find the value of k, which is the constant. The y and x variables are in both equations already, and there is only the 1/9, which is k.

Therefore, the constant of proportionality is 1/9. We can check this answer by putting 1/9 back into the equation. y = 1/9 (x)    or    y=  x/9.

Answer:

77 in ^2 is the best estimate

Step-by-step explanation:

We can get the total area from the sum of the triangle and the semi circle

semicircle

1/2 the area of the semicircle

A = 1/2  pi r^2

   1/2 (3.14) ( 4^2)

    25.12

Now find the area of the triangle

The base is 16 -r = 16-4 = 12

The height is 8

A = 1/2 bh

   = 1/2 (8) (12)

   = 48

The total area is 25.12+48 =73.12

Step-by-step explanation:

2.5(6x-4)=10+4(1.5+0.5x)

Distribute

15x -10 = 10 + 6 +2x

Combine like terms

15x -10 =16+2x

Subtract 2x

13x -10 = 16

Add 10

13x= 16+10

13x = 26

Divide by 13

13x/13 = 26/13

x =2

Answer:

x=2

Step-by-step explanation:

2.5(6x-4)=10+4(1.5+0.5x)

Distribute.

2.5*6x-2.5*4=10+4*1.5+4*0.5x

15x-10=10+6+2x

Combine like terms.

15x-10=16+2x

Add 10 to both sides

15x-10+10=16+10+2x

15x=26+2x

Subtract 2x from both sides.

15x-2x=26+2x-2x

13x=26

Divide both sides by 13

x=2

Answer:

The last one

Step-by-step explanation:

Answer:

4 is the correct answer, I believe.

Reasoning:

The first line must be graphed with a constant y of 3, and stop before -2. Which it does on all 4 graphs.

The third line must, when extended, pass through point (0, -3). Only graph 1 and 4 follow that criteria, so it is not 2 or 3.

The second line's y-intercept must be 2, as well as begin at -2 and end before 2. Only graph 4 correctly plots this equation.

Answer:

x = -3

y = 7

Step-by-step explanation:

x + 3y = 18

-3x - 12y = -75

multiply first equation by 4

4 × (x + 3y) = 18 ➡ 4x + 12y = 72

now add the two equations up

4x + 12y - 3x -12y = 72 - 75 (-12y will eliminate 12y)

x = -3

Answer:

Solve for x:

56 x^2 + 4 = 77

Subtract 4 from both sides:

56 x^2 = 73

Divide both sides by 56:

x^2 = 73/56

Take the square root of both sides:

Answer: |

| x = sqrt(73/14)/2 or x = -sqrt(73/14)/2

identity property of multiplication-

a*1=a

Step-by-step explanation:

i cant give u an exact answer as u didnt give Micheals answers so i just gave some examples about what addition and multiplication identity property should look like. Identity property's concept is to keep the same identity. Basically, "a" shouldnt change. In addition, to keep a the same all u hv to do is add 0 as anything plus 0 is the same. for multiplication, just multiply by 1. Hope this helps!!

Answer:

4 or 5

Step-by-step explanation:

Answer:

The correct answer is a) (6, 3).

Step-by-step explanation:

The midpoint is determined in straight lines by subtracting the larger x-coordinate value and the smaller x-coordinate value. In this case, it is 10 - 2. You earn 8. Then, divide this answer by 2. So, you get 4. Finally, either subtract this from the larger x or the smaller x. You will earn 6. Since you are solving for a straight line, your y-coordinate will be the same as the others. Therefore, A is your answer.

The answer is (6,3)

Answer:

3808

Step-by-step explanation:

Given the sequence: 13,19,25

First Term, a=13

Common Difference, d=19-13=25-19=6

Since we have a common difference, the sequence is an arithmetic sequence.

We determine the sum of any nth term of an arithmetic sequence using the formula:

[tex]S_n=\frac{n}{2}[2a+(n-1)d] \\n=34, a=13, d=6\\$Therefore:\\S_{34}=\frac{34}{2}[2(13)+(34-1)*6]\\=17[26+33*6]\\=17[26+198]\\=17*224\\S_{34}=3808[/tex]

The sum of the first 34 terms is 3808.
