Dilation and rotation is a series of transformations that would produce a figure that is similar to the original figure but not congruent with it.

Transformation of dilation and rotation:

Rigid transformations, such as rotations, reflections, and translations, do not alter the size or shape of a figure; rather, they only move it. The congruence is preserved by these hard changes.

However, because dilation alters a shape's size, they are not hard transformations. The ratio of matching sides would be equal to the scale factor used in the dilatation; the form would remain the same, just the size would vary. This would provide us with a comparable but in congruent value.

The solution to the system of linear equations x 3y =- 2 is (x, y) = (6, -2).

The solution to the system of linear equations x 3y =- 2 can be found by using a method such as substitution or elimination.

One possible method is substitution, where we solve one equation for one variable in terms of the other, and then substitute that expression into the other equation.

For example, we can solve the equation x + 3y = -2 for x in terms of y: x = -3y - 2. Then we can substitute this expression into the second equation: -3y - 2 + 3y = -2, which simplifies to y = -2.

Then we can substitute this value back into the first equation to find x: x = -3(-2) - 2 = 6.

So the solution to the system of linear equations x 3y =- 2 is (x, y) = (6, -2).

In conclusion, The system of linear equations x + 3y = -2 can be solved by using the method of substitution. By solving one equation for one variable in terms of the other, and substituting that expression into the other equation, we find that the solution to the system is (x, y) = (6, -2).

The property of substitution states that if an expression is equal to a second expression, then replacing a part of one expression with the corresponding part of the other expression will also result in an equivalent expression.

The property of substitution is a fundamental concept in algebra that allows us to manipulate equations and expressions. This property states that if two expressions are equivalent, then replacing a part of one expression with the corresponding part of the other expression will also result in an equivalent expression. This allows us to make substitutions in equations and expressions in order to find solutions. This property is essential when solving equations, since it allows us to replace unknown variables with known values, enabling us to find the solution. It is also important when simplifying expressions, since it allows us to replace parts of the expression with simpler parts in order to find the simplified form.

-120 + 238 = -60 + 178

118 = 118

Step-by-step explanation:

Given equations are

2x+3y=13 ....(1)

4x+y=11 .....(2)

multiply the equation (2) by 3, we get

⇒12x+3y=33 .....(3)

Algebraic expression can be defined as the combination of  constants , variables and operators.

​We write 4 thousand as 4,000

We write 40 thousand as 40,000

We write 400 thousand as 400,000

The value of each place is ten times the value of the place immediately to the right.

So:

40,000 is 10 times 4,000

400,000 is 10 times 40,000.

4,000,000 is 10 times 400,000.

Thus, 400,000 = 10 *40,000, and there are about 10 times as many fourth graders in Texas as there are in Mississippi.

Also, 4,000,000 = 10* 400,000, and there are about 10 times as many fourth graders in the US as there are in Texas.

Finally, to go from 4,000 to 4,000,000, we have to multiply by 10 three times. We see that

10*10*10 = 10 * 100 = 1000

A 1/3 scale factor is a constant of dilation that is used to change the size of a figure by a factor of 1/3. A dilation is a transformation that changes the size of a figure while preserving its shape.

In a dilation, the scale factor is multiplied by the coordinates of each point on the figure to determine the new coordinates of the dilated figure. If the scale factor is 1/3, then the coordinates of each point on the figure will be multiplied by 1/3, meaning that each point on the figure will be moved one-third as far from the origin as it was before the dilation.

The result of this is that the dilated figure will be smaller than the original figure and will have a scale factor of 1/3. It's important to note that if the scale factor is less than 1, the dilation will reduce the size of the figure and if the scale factor is greater than 1, the dilation will increase the size of the figure.
