Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral EFGH on the graph below.
Which rule best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral EFGH?
Answers
Option D is correct (x, y) → (2.5x, 2.5y).
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral EFGH on the graph below.
Since Scale factor:
A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
In our case,
A dilation of 2.5 because side AB is 4 units and EF is 10 units and if you divide 10/4 will get you with your scale factor.
thus, Scale factor is 2.5
Therefore, best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral EFGH is D. (x, y) → (2.5x, 2.5y)

8. Conduction. (Conduction is the transfer of heat that happens when particles collide with each other. It can happen in solids, liquids, and gases.)
Before the pan is placed on the burner, its particles are moving at the same average speed. The whole pan is at the same temperature. The hot burner is at a much higher temperature. In other words, the particles that make up the burner are moving at a greater average speed and therefore have greater thermal energy.
8b. Convection. During convection, however, the particles themselves move. This happens only in liquids and gases because the particles in solids are stuck in place and cannot move.
Answer:
8. Conduction happens it transfers the heat when particles collide with each other. Before the pan is placed on the burner, its particles are moving at the same average speed. The whole pan is at the same temperature. The hot burner is at a much higher temperature, than the pan which causes the particles to move at a uneven speed.
8 b. Convection. During convection, the particles move. This happens only to liquids and gases particles because in solid objects the particles get stuck which doesn’t allow them to move around.

Hello!

Use the slope formula along with provided points to solve for the slope.
We can use the points (-4, -1) and (0, -3) and plug these values into the equation:

(1 point)
12 square units
24 square units
48 square units
96 square units
Answers
To figure out the area of a parallelogram, we need to identify its formula. However, I do know the formula, which is Area = Base x Height.
Area = Base x Height
Area = 8 x 12
= 96 cm squared
Therefore, the answer it 96 cm squared. By the way, I recommend that you review and comprehend the topic regarding area. Try memorizing all formulas for the shapes.
Rectangle & Square: Area = length x width
Triangle: Area = base x height
2
Trapezoid: Area = (Base 1 + Base 2) x h

Pararellogram: Area = base x height
Circle: Area = pi x r sqaured
Those are all the formulas I can recall; however, there might be more.

Answers
Answer:
x=2
Step-by-step explanation
The First step is to distribute the '2" into the parenthesis.
thus, you have 8x + 8 = 24
now we need to get x by itself so we will subtract 8 from both sides to get 8x by itself.
we know have 8x = 16
now divide by 8 to get x
x=2
10x- (- 4 + 7x
answer if you can :)
Answers
Answer:
17x + 4
Step-by-step explanation:
The -(- would be turned into a positive due to the rule of two negatives makes a positive. You wouldn't add the 4 into either of the numbers with a variable, you would only add the 10x and 7x.
Answer:
3x+4
Step-by-step explanation:
Apply the distributive property to get 10x - -4-(7x). Now we can turn the two negatives into a positive to get 10x+4-7x. Now, subtract 7x from 10x to get 3x. This will leave you with 3x+4.

Step-by-step explanation:
In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal. It can also be defined as a parallelogram containing a right angle. A rectangle with four sides of equal length is a square. The term oblong is occasionally used to refer to a non-square rectangle. A rectangle with vertices ABCD would be denoted as ABCD.
