Answer:

x_2y=15

x_4y=_3

_6y=12

divide both sides by 6

y=_2

substitute y for x

In equation 1

Marissa says that lines a and d will eventually intersect is a wrong statement as they are skew lines. Therefore option D is correct.

A and D are both in different planes, skew lines are line that will never intersect because they are noncoplanar, meaning they are never in  the same plane. If they aren't in the same plane, they can't intersect.

Two or more lines that doesn't have any intersections but they are not parallel.

Skew lines are also called as agonic lines. Since two lines in a plane must be parallel or intersect ,skew lines can only exist  in three dimensions or more dimensions.

the domain of the graphed function is D: [-5, 3]

For a function f(x), we define the domain as the set of the inputs of the function.

So, to identify the domain, we need to look a the horizontal axis.

Doing that, we can see that the first value in the horizontal axis is x = -5, and the last value is x = 3.

Notice that in both cases we have solid dots, which means that these values do belong to the domain.

Then the domain of the graphed function is D: [-5, 3]

The relationship between the figure JKLM and it's image, J'K'L'M' following a dilation by a scale factor of 1 is that JKLM and J'K'L'M' have the same dimensions, and location

Scale factors are numbers that are used to multiply a quantity to scale it by a given rate.

Part A

In order to easily describe the relationship between the image J'K'L'M' and the original figure JKLM, the point J can be taken as the origin such that the image vertices are obtained by dilating the points on the original figure in their original direction relative to J using the specified scale factor.

The coordinates of the vertices of JKLM relative to J are;

J(0, 0), K(6, 0), L(6, -6), M(0, -6)

Distance of K from J = 6 - 0 = 6 units to the right of K

Therefore, using a scale factor of 1;

The distances of the vertices of square J'K'L'M' from point J are the same and in the same direction as the distances of the vertices of square JKLM from point J.

The vertices of J'K'L'M' using a scale factor of 1 are therefore located at the same coordinates as the vertices of square JKLM

There are 1680 ways to construct the octahedrons.

Here,

Eight congruent equilateral triangles, each of a different color, are used to construct a regular octahedron.

An octahedron has 8 equilateral triangles.

We have to find number of ways to construct the octahedron.

What is Regular octahedron?

An octahedron is a polyhedron with eight faces. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.

Now,

An octahedron has 8 equilateral triangles.

We have to fix 2 faces before applying the colors.

So, the first face that can be fixed for any of the 8 faces but each faces are similar.

Hence, there are 8/8 ways.

And, When we fix one face, three adjoining faces are similar.

So, we have 7 colors for the second face.

Hence, 7/3 ways

Now, we can place any color anywhere, it will be different arrangement.

So, 6! ways.

Hence, Total number of ways = (8/8) * (7/3) * 6! = 7 * 6 * 5 * 4 *2 = 1680

So, There are 1680 ways to construct the octahedrons.

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. A simple random sample is meant to be an unbiased representation of a group.

Random sampling, or probability sampling, is a sampling method that allows for the randomization of sample selection, i.e., each sample has the same probability as other samples to be selected to serve as a representation of an entire population.

Simple random sampling is the randomized selection of a small segment of individuals or members of a whole population. It provides each individual or member of a population with an equal and fair probability of being chosen. The simple random sampling method is one of the most convenient and simple sample selection techniques.

Simple random samples are determined by assigning sequential values to each item within a population, then randomly selecting those values.

The coordinates of point D is (- 3, - 7).

A midpoint is a point that partitions a line segment in two parts of equal length. First, we must find the coordinates of point B by using the midpoint formula:

B(x, y) = 0.5 · A(x, y) + 0.5 · C(x, y)

B(x, y) = 0.5 · (- 9, - 4) + 0.5 · (- 1, 6)

B(x, y) = (- 4.5, - 2) + (- 0.5, 3)

B(x, y) = (- 5, 1)

And the location of point D is found by using the midpoint formula again:

E(x, y) = 0.5 · B(x, y) + 0.5 · D(x, y)

(- 4, - 3) = 0.5 · (- 5, 1) + 0.5 · D(x, y)

(- 4, - 3) = (- 2.5, 0.5) + 0.5 · D(x, y)

(- 8, - 6) = (- 5, 1) + D(x, y)

D(x, y) = (- 8, - 6) - (- 5, 1)

D(x, y) = (- 3, - 7)
