Given:

The set is

$\{(3,4),(4,4),(8,-1)\}$

To find:

The correct option for the given set which represents the quality that is not in the given set.

Solution:

We have,

$\{(3,4),(4,4),(8,-1)\}$

It is the set of ordered pairs. So, it is a relation.

For each x-value there is a unique y-value value. So, it is a function.

All elements are real numbers but they not distinct and they are in ordered pairs. So, the given set is not a set of real numbers.

In one to one functions each image has exactly one preimage and each preimage has exactly one image.

In the given set 4 has two preimages 3 and 4. So, the given set is not a one to one function.

Therefore, the correct options are C and D.

Hello!!

Well, the angles in a triangle must add up to 180 degrees.
So, since one angle is 40 degrees, the other two angles must add up to 140 degrees.
A quick look over the answer choices will show that option C, 35 degrees and 105 degrees, is the only possible answer.

Hope this helps!! Let me know if you have ANY questions.

In the equation y=a(x-h)^2+k, the "k" translates the parabola in what manner?

stellarik [79]

Answer:

k is the vertical shift

Step-by-step explanation:

y=a(x-h)^2+k

This gives the parabola in vertex form

(h,k) is the vertex where h is the x coordinate and k is the y coordinate

k is the vertical shift

Solve for the variable

ICE Princess25 [194]

Answer:

Step-by-step explanation:

Try to get the variable alone by dividing 5/8 on both sides of the equations.

That cancels out the 5/8 on the left leaving u and the 25 on the right turns into 40. It turns into 40 because 25 divided by 5/8 equals 40.

rosalva and Jake walked a certain distance each day they recorded the distance in the table shown below. what is the difference

shepuryov [24]

The answer is: 891 meters

Explanation:

First add Rosalva's distances = 1.5 + 0.69 + 1.04 + 2.1 = 5.33 km = 5.33 * 1000 m = 5330 meters

Second add Jake's distances = 1450 + 1590 + 1204 + 1977 = 6221 meters

Now take the difference Jake's and Rosalva's four day distances: 6221 - 5330 = 891 meters

The vertices of AABC are A(-4,5), B(-2,3), and C(-3,3). If AABC is reflected across the line y = 1 to produce the image AA'B'C',

labwork [276]

The distances of the preimage and the image from the line of reflection are equal

The coordinates of C' after a reflection across the line y = 1 are (-3, -1)

The reason the above value is correct is as follows:

The given vertices of the ΔABC are; A(-4, 5), B(-2, 3) and C(-3, 3)

The line of reflection to produce the image ΔA'B'C' is the line y = 1

Required:

To find the coordinates of C' after a reflection across the line y = 1

Solution:

Let (x, y) represent the coordinate of the point C

x-coordinate value:

The line y = 1 is parallel to the x-axis, therefore, the x-value will remain the same following a reflection across the x-axis

Taking the point C' as the image of the corresponding point C(-3, 3), we have that the x-coordinate of the point C' is also -3

x = -3

y-coordinate value:

The difference between the coordinate of the preimage and the reflecting line is the same as the difference between the reflecting line and the coordinates of the image

The y-value distance of the point C(-3, 3), from the line y = 1 is 3 - 1 = 2

Therefore, the y-value distance of C' from the reflecting line is given as follows;

1 - y = 2

y = 1 - 2 = -1

y = -1

Therefore, the coordinates of the point C' is (x, y) = (-3, -1)
