(-6, 14) and (4.-16)

(-2.16) and (2.-20)

Step-by-step explanation:

we know that

If two lines intersect, then their slopes are different

The formula to calculate the slope between two points is equal to

Find the slope of the given line

points (-2, 12) and (3, -23)

substitute in the formula

Verify each case

case 1

(-3, 19) and (6.-44)

substitute in the formula

Compare with the slope of the given line

The slopes are the same

therefore

The lines not intersect because are parallel lines

case 2

(-5,32) and (3.-24)

substitute in the formula

Compare with the slope of the given line

The slopes are the same

therefore

The lines not intersect because are parallel lines

case 3

(-4, 17) and (5.-28)

substitute in the formula

Compare with the slope of the given line

The slopes are different

therefore

The lines intersect

case 4

(-6, 14) and (4.-16)

substitute in the formula

Compare with the slope of the given line

The slopes are different

therefore

The lines intersect

case 5

(-2.16) and (2.-20)

substitute in the formula

Compare with the slope of the given line

The slopes are different therefore

The lines intersect

Answers

Answer:

The expression you provided involves a limit, a summation, and variables. To provide a clear and concise answer, I will break down the components of the expression and explain their meaning.

1. lim (0 to 100): This notation represents the limit as a variable approaches a certain value. In this case, the variable is not specified, so I will assume it represents the value of M.

2. Σ (k=1 to n): This symbol represents a summation, where the variable k takes on values from 1 to n. The value of n is not specified in the expression you provided, so I cannot calculate the exact summation.

3. In n: I'm not sure what "In n" refers to in this context. It could be a typo or an incorrect notation. Can you please clarify or provide more information?

Based on the information provided, I can explain how to evaluate a general expression involving a limit and a summation.

To evaluate the expression, follow these steps:

1. Determine the values for M and n. These values may be provided in the problem or given as part of the context.

2. Plug in the values of M and n into the expression.

3. Evaluate the summation by substituting k with the values from 1 to n and summing up the results.

4. Finally, take the limit as M approaches the specified value, if applicable.

If you provide more information or clarify the meaning of "In n," I can provide a more specific answer.

How old is Jane?

Answers

How old is jane she is 9 and 1/4

Step-by-step explanation:

So we know that paul is 11 and 5/6

and greg is 1 and 1/3 younger than paul

and jane is 1 and 1/4 younger than greg

First we got to the great common factor of the three facrtion

its 12

so paul is 11 and 10/12

greg is 1 and 4/12

jane is 1 and 3/12

subtract paul age to gregs which is 10 and 6/12 simpfly to is 10 and 1/2

the subtract gregs age to janes which is 9 and 3/12 simply is 9 and 1/4

The Middle school team scored three field goals worth three points each and two touchdowns worth six points each, Including extra points. Write a numerical Expression to find the team's score.

Answers

Answer:
21
Step by step explanation:
So, what we know is that we have 3 field goals, each worth 3 points, and 2 touchdowns, each worth 6 points. So we can do: 3 * 3 + 2 * 6. To break this down we first must do 3 * 3. This gets us an answer of 9, we then must do 2 * 6. Which gives us an answer of 12. Now that we have multiplied the 2, we may add, 9 + 12 = 21. Meaning our answer is 21. I hope this helped you out!

When the value of a will be 2 and 3 from 1, The square formed will be dilated by a scale factor of 2 and 3.

What are transformations?

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

We know, A square has side lengths that are equal to each other.

Given, We draw a diagram of a + a + a + a, This will form a square.

Now, When the values of a will be 1 we will have a square with side

lengths 1.

Now, When a = 2 and a = 3 the square will be dilated by a scale factor of 2 and 3.
