The transformation is non rigid
What transformations ?Transformations involve the rotation, reflection, or translation of forms on a coordinate plane. Transformational geometry is a fresh viewpoint on geometry that Felix Klein suggested in the 19th century. The majority of geometric proofs rely on the transformations of objects. Any image in a coordinate plane can be changed using transformations. Applying the transformational laws will help you better understand the graphics in video games. Learn to recognize transformations, comprehend function transformation principles, and investigate the various forms of transformations.
What is non rigid transformations ?Non-Rigid Transformations actually alter the original object's structure. Scaling, for instance, allows us to make our object larger or smaller. Alternatively, shearing can be used to "push" it up or to the side. In essence, non-rigid transformations allow an object's size to change.
because the size became small as compare to pre image it is non rigid transformation

Select the correct equation and correct answer to solve for X using the triangle below.
The correct equation to solve for x is 2(2x-15)=2x-8 , and the value of x is 11 .
in the question ,
from the given figure , we can see that RL=LQ and PK=KQ which means
that L and K are the mid points of sides RQ and PQ respectively .
The Mid Point Theorem states that
If the line segment adjoining the mid points of any of the sides of the triangle then the line segment is said to be parallel to the third side and is half of the length of third side .
which means LK parallel to RP and RP/2=LK ( ... by mid point theorem)
Substituting the values of LK = 2x-15 and RP = 2x-8 .
(2x-8)/2=2x-15
Multiplying both sides by 2
2x-8 = 2(2x-15)
So, the equation to solve for x is 2(2x-15)=2x-8
Simplifying further
2x-8 = 4x-30
4x-2x= 30-8
2x = 22
x = 11
Therefore , the correct equation to solve for x is 2(2x-15)=2x-8 , and the value of x is 11 .

25×10 to the power of -3 to standard form
The number 25×10 to the power of -3 written in the standard form is 2.5×10⁻⁴.
What is meant by the term scientific notations?Scientific notation is a way of displaying very large or extremely small numbers in a more simplified format. We know that whole numbers could be extended indefinitely, but such large numbers cannot be written on a sheet of paper. The scientific notation allows us to represent very large or very small numbers by multiplying single-digit numbers by 10 raised to a power of a respective exponent. If the number is so very large, the exponent is positive; otherwise, it is negative. For a better understanding, learn power and exponents.The given number is;
25×10 to the power of -3
This can be written as;
= 25×10⁻³
Now, as per the standard form, the number should contain only one digit to the left of decimal.
Thus, shifting one decimal to the left of the 5 and converting the power by adding one to the current power,.
The number becomes;
= 2.5×10⁻⁴.
Thus, the number written in the standard form is 2.5×10⁻⁴.

Find the y intercept (if there is one) put your answer as a ordered pair.
(-2,6) (1,6)
The y-intercept of the line that passes through points (-2,6) and (1,6) in an ordered pair is ( 0,6 ).
What is the y-intercept of the line that passes through the given points?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
The slope of a line is expressed as change in y over change in x.
Slope m = (y₂-y₁)/(x₂-x₁)
Given the data in the question;
Point A ( -2,6 )
x₁ = -2y₁ = 6Point B ( 1, 6 )
x₂ = 1y₂ = 6First, we determine the slope of the line.
Slope m = (y₂-y₁)/(x₂-x₁)
Slope m = ( 6 - 6 )/( 1 - ( -2) )
Slope m = ( 0 )/( 1 + 2) )
Slope m = ( 0 )/3
Slope m = 0
Now, we can determine the y-intercept b, using the slope and coordinates of 1 point.
y = mx + b
6 = (0)(1) + b
Solve for b
6 = 0 + b
b = 6
Therefore, the coordinates of the y-intercept is ( 0,6 ).

3x-1/5=x+1/3 pls help me
Answer:
x=4/15
Step-by-step explanation:
first you need to make common denominators for 1/5 and 1/3
the common denominator is 15
5*3=15, 3*5=15. 1*3=3, 1*5=5
new equation:3x-3/15=x+5/15
now subtract x from both sides: 3x-3/15=x+5/15
-x -x
2x-3/15=5/15
now you can add 3/15 to 5/15
2x=8/15
now for the last step, divide by 2 because there are 2 x's
2x/2=x 8/15 /2=4/15
x=4/15
Answer:
4/15
Step-by-step explanation:
3x-1/5 = x+1/3
make a common denominator
3x -3/15 = x + 5/15
next you can take away one x from both sides
2x - 3/15 = 5/15
then we want to have x alone on one side and everything else on the other
2x = 5/15 + 3/15
2x = 8/15
1x = 8/15 ÷ 2
1x = 8/30
simplify that
x = 4/15

solution a is 2% alcohol and solution b is 5% alcohol. she uses 800 milliliters of solution A how many milliliters of solution b does she use if the resulting mixture is a 3% alcohol situation
She uses 800 mL of solution A; that is, 2% of those 800 mL is alcohol
Alcohol on a:
2% of 800 = 2*800/100 = 16mL
If we use x mL of b, the amount of alcohol is:
5% of x = 5*x/100 = x / 20
Total amount of alcohol: 16 + x/20
Total amount of solution mixture: 800 + x
The ratio:
(16 + x/20) / (800 + x) = 3%
(16 + x/20) / (800 + x) = 3/100
1600 + 5x = 2400 + 3x
Solving for x:
5x - 3x = 2400 - 1600
2x = 800
x = 400 mL
She used 400 mL of solution b
The fuel economies in miles per gallon (mpg) for nine vehicles are listed below. If one more vehicle is added to the list with a rate of 40 mpg, how will this affect the mean and median?
A. The mean and median will both increase.
B. The mean will increase and the median will decrease.
C. The mean will increase and the median will not change.
D. The mean will decrease and the median will not change.
Option C. The way that the change would affect the mean and the median is that The mean will increase and the median will not change.
How to solve for the mean and the medianWe will find the mean and the median before the 40 was added and after it was added
Before it was added
Mean = 16 + 18 + 20 + 24 + 24 + 24 + 24 + 31 + 32 / 9
= 213 / 9
= 23.67
The median is 24
After we have added 40 the mean would be
16 + 18 + 20 + 24 + 24 + 24 + 24 + 31 + 32 + 40 / 10
= 253 / 10
= 25.3
The median would be 24 + 24 / 2
= 48 / 2
= 24
Hence we can see that the mean got to be higher while the median still remained as 24.

times what Olivia spent. In total, they spent $54. How much did each girl

By solving a system of equations we can see that Olivia spent $14 and Camiller spent $37.
How much did each girl spend?Let's define two variables:
x = Amount that Olivia spends.y = Amount that Camille spendsWe know that " Camille spent $14 less than three times what Olivia spent" so we can write:
y = 3*x - 14
And "In total, they spent $54"
x + y = 54
Then we have a system of equations:
y = 3*x - 14
x + y = 54
Replacing the first equation into the second one, we get:
x + 3x- 14 = 54
4x - 14 = 54
4x = 54 + 14
4x = 68
x = 68/4 = 17
Now that we know the value of x, we can try to find the value of y.
y = 3x - 14 = 3*17 - 14 = 37

A constant force is applied to an object, causing the object to accelerate at 12.50 m/s/s. What will the acceleration be if both the force and the
mass are doubled? Round to two decimal places and use SI units.
Answer:
a₂ = 12.5 m/s²
Step-by-step explanation:
Applying the 2º Newton's Law:
∑F = m * a
F₁ = m₁ * a₁
F₁ = m₁ * 12.5
F₁ = 12.5m₁
F₂ = m₂ * a₂
2F₁ = 2m₁ * a₂
a₂ = F₁ / m₁
So:
a₂ = 12.5m₁ / m₁
a₂ = 12.5 m/s²

This is so because the product has a higher order of precedence
So, it must be evaluated first
So, the correct solution is

Find the x-intercept of the line that passes through (-3,4) and is perpendicular to the graph of x-2y=7
Answer:
x - intercept = - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x - 2y = 7 ( subtract x from both sides )
- 2y = - x + 7 ( divide through by - 2 )
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{7}{2}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then
y = - 2x + c ← is the partial equation of the perpendicular line\to find c substitute (- 3, 4 ) into the partial equation
4 = 6 + c ⇒ c = 4 - 6 = - 2
y = - 2x - 2 ← equation of perpendicular line
to find the x- intercept let y = 0 into the equation and solve for x
- 2x - 2 = 0 ( add 2 to both sides )
- 2x = 2 ( divide both sides by - 2 )
x = - 1
the x- intercept of the perpendicular line is - 1 or (- 1, 0 )
