congruent means they are the exact same shape.

Answer:

y = -3x + 22

Step-by-step explanation:

To find m, find the change in y and divide it by the change in x.

For example, the change in y between 19 and 13 is -6. Then determine the change in x. For example, since we determined the change in 19 and 13, let's look at the change in the x coordinates that pair with 19 and 13: 1 and 3. The change in x between 1 and 3 is 2. Now divide the change in y by the change in x: -6/2 = -3. So now we have the equation y = -3x + b, but we still need to figure out b, or the y-intercept. To do this, we need to figure out a pattern in the table to find out what y is equal to when x = 0, the definition of a y-intercept. From just the table alone, it looks like for every 2 units the x-coordinate decreases, the y-coordinates increases by 6. We could also just as easily say that for every 1 unit the x-coordinate decreases, the y-coordinate increases by 3. From this definition, if we look at the coordinate (1, 19), if we were to decrease 1 from the x-coordinate, we would have to increase the y-coordinate by 3 which we can write as (x - 1, y + 3). So, we would get (0, 22). So, when x = 0, y = 22.

B) dilation of 1.5

Step-by-step explanation:

yes

Answer:

Dilation of 1.5

Step-by-step explanation:

The way I do these equations is pick one coordinate axis and work with that. So for point K, it goes from X & Y coordinate 1 to 1.5, Point I goes from Y coordinate 2 to 3, and Point J goes from y coordinate 2 to 3 again.

Answer:

let the 1st number be x

then second number is x+2

then third number is x+2+2

according to question

sum of three consecutive odd integers is 237.

hence, x+x+2+x+2+2=237

3x+6=237

3x=237-6

3x=231

x=231/3

x=77

therefore 1st integer is 77

2nd integer is 77+2=79

3rd integer is 77+2+2=81

Answer:

77, 79, 81

Step-by-step explanation:

You can represent the equation as follows:

x + x + 2 + x + 4 =237

Combine like terms.

3x + 6 = 237

Subtract 6 from both sides.

3x = 231

Divide both sides by 3.

x = 77

Now, add 2 to 77 to determine the second integer.

77 + 2 = 79

Add 4 to 77 to determine the third integer.

77 + 4 = 81

Answer:

[tex]\sqrt[10]{77}[/tex]

Step-by-step explanation:

[tex]77^\frac{1}{10}[/tex] is the same as [tex]\sqrt[10]{77^1} ,[/tex] or simply [tex]\sqrt[10]{77}[/tex]

77^1/10 can be written as [tex]\sqrt[10]{77}[/tex]

The principal nth root of a is written as n√a , where n is a positive integer greater than or equal to 2. In the radical expression, n is called the index of the radical.

A radical symbol √ is used to represent a square root; the number or expression included within the radical symbol, designated by the letter a below, is known as the radicand.

We have that [tex]77 ^ {1/10}[/tex].

Now, if we have given that √4 we can write it as [tex]\sqrt[2]{4}[/tex]

Again, if we have [tex]7^{1/3}[/tex] we can write it as [tex]\sqrt[3]{7}[/tex]

Similarly we can write 77^1/10 as  [tex]\sqrt[10]{77}[/tex]
