A geometric figure is dilated by a scale factor of 4/3with the origin as the center
of dilation. Which of the following algebraic representations best describes the
dilation?

Answers

Answer: Scale Factor (Dilation) The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs.

Step-by-step explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

Step-by-step explanation:

Answer: The error made was that the x from 24xy wasn’t taken out. Because if you multiplied 6x and -4xy it would NOT equal -24xy. So what she should done was also 6x(3-4y)

4.) Write the equation of the line shown below? SHOW WORK!

Answers

Answer: y=1/5x-3/5

Explanation:

Use points (3,0) and (-1,-1) to find the slope and y-intercept.

Use y1-y2/x1-x2 to find slope

-1-0/-1-4
=-1/-5
=1/5

So the slope is 1/5

Then use y-y1=m(x-x1) to find the y-intercept.

y-0=1/5(x-3)

y-0=1/5x-3/5

So the equation is y=1/5x-3/5

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

Given;

we have number line that can be used to find the distance between (–1, 2) and (–5, 2)

The y-coordinates of the points are the same, therefore the distance between those points will be the difference of the x-coordinates. The first number line shows those x-coordinates plotted properly which can be used can be used to find the difference between them.

Therefore the correct answer is option A

What is a function?

"A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B. A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. f = {(a, b)| for all a ∈ A, b ∈ B}

A relation is said to be a function if every element of set A has one and only one image in set B.

Here, the given function is y = - 2x.

When the value of 'x' is - 2, the value of 'y' is

= - 2(- 2) = 4.

When the value of 'x' is - 2, the value of 'y' is

= - 2(0) = 0.

When the value of 'x' is 2, the value of 'y' is

= - 2(2) = - 4.

Therefore, the set of values of for the given function are (- 2, 4), (0, 0), (2, -4).

how do i solve Solve 4/9=x/45.

Answers

You multiply 45 on both sides and get x=20

Answer:

x = 20

Step-by-step explanation:

I would say that there are two ways to solve this.

First way:

You could simply this equation be cross multiplying.

4/9 = x/45 → 180 = 9x

Next, divide 180 by 9.

20 = x → x = 20

Second way:

Considering that fraction bars mean division, you could cancel out x/45 by multiplying both fractions by 45.

4/9 = x/45 → 20 = x → x = 20

There are 2 mixtures of light purple paint. Mixture A is made with 5 cups of purple paint and 2 cups of white paint. Mixture B is made with 15 cups of purple paint and 8 cups of white paint. Which mixture is a lighter shade of purple? Explain your reasoning. *

Answers

Answer:

Mixture B

Step-by-step explanation:

The mixture with more white paint would have a lighter shade of purple.

Mixture A is 2/7 white paint while Mixture B is 8/23 white paint.

2/7 is approximately 0.286

8/23 is approximately 0.348

0.348 > 0.286 so Mixture B is made of more white paint than Mixture A and therefore is a lighter shade of purple.
