Which of the following transformations does not
preserve congruence?
F. (x,y) → (-x, -Y)
G. (x, y) = (-y, -x)
H. (x, y) = (x + 9.y + 9)
J. (x,y) → (9x, 9y)
Answer:
(9x, 9y) dilation
Step-by-step explanation:
(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

Step-by-step explanation:
6c^2 - 5d + 8 when c =5 and d=4
Answer:
138
Step-by-step explanation:
First, we can simply replace the variables with their numerical values.
Whenever you see a number with a letter (variable) in front of it, this means to multiply.
c=5 and d=4
6 × 5^2 - 5 × 4 + 8
Since there are multiple operations in this expression, we must use PEMDAS.
ParenthesisExponentiation (exponents)Multiplication/Division (Solve whichever comes first)Addition/Subtraction (Solve whichever comes first)--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Now, we can apply the operations.
There are no parenthesis.
In this expression, exponents are present.
6 × 5^2 - 5 × 4 + 8
6 × 25 - 5 × 4 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is multiplication.
6 × 25 - 5 × 4 + 8
150 - 5 × 4 + 8
150 - 20 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is subtraction.
150 - 20 + 8
130 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is addition.
130 + 8
158
Therefore, 6 × 5^2 - 5 × 4 + 8 = 138.
According to a survey of workers, 5/25 of them walk to work, 1/25 bike, 4/25 carpool, and 15/25 drive alone. What percent of workers walk or bike to work?
Answer: 24%
Step-by-step explanation:
First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.
This is:
= 5/25 + 1/25
= 6/25
Then convert this to a percentage:
= 6/25 * 100
= 24%

How much money will Louis save on the total cost because of the markdown?
Answer:
Part ACalculate sale price and add sales tax:
20% off $339 add tax ⇒ $339*0.8*1.085 = $294.25 ≤ $30015% off $310 add tax ⇒ $310*0.85*1.085 = $285.90 ≤ $30025% off $365 add tax ⇒ $365*0.75*1.085 = $297.02 ≤ $30020% off $300 add tax ⇒ $300*0.8*1.085 = $260.40 ≤ $300Each price is acceptable as less than $300
Part BMarkdown with tax added:
25% off $328 add tax ⇒ $328*0.75*1.085 = $266.91Without discount, the price with the tax added:
$328*1.085 = $355.88The difference is the amount Luis has saved:

Answer:
x = 11
Step-by-step explanation:
The given angles are corresponding angles and are congruent, then
12x - 9 = 10x + 13 ( subtract 10x from both sides )
2x - 9 = 13 ( add 9 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11

Answer:
I think it's 45 degrees
Step-by-step explanation:
<c is 90 degrees and the interior of every triangle is 180 degrees so then we subtract 90 from 180 which is 90 so we divide 90 by two since b and a seem to be equal which is 45 degrees.

If line segment AB,A(9,3) and B(-6,-9), what scale factor was used to dilate if new line is at A'(3,1) and B'(-2,-3)?
Answer:
The scale factor is 1/3
Step-by-step explanation:
Here, we want to get the scale factor used in dilating the original segment
As we can see;
(9,3) turned to (3,1)
looking at this , we can see that both coordinate values were divided by 3
So what this mean is that the particular scale factor used is reduction by 1/3
This is the case with the other point as (-6,-9) turned to (-2,-3)

Ann runs a day care center. Of the last 18 children to enroll at the day care center, 8 of them have been elementary school students. Considering this data, how many of the next 9 children to enroll should you expect to be elementary school students?
We would expect that 4 of the next 9 children to enroll will be elementary school students.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If 8 out of the last 18 children to enroll at the daycare center were elementary school students,
We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:
= 8/18
= 4/9
This means that 4 out of every 9 children enrolled were elementary school students.
If we want to predict how many of the next 9 children to enroll will be elementary school students,
We can use this ratio:
4/9 of 9 children
= (4/9) x 9
= 4
Therefore,
We would expect that 4 of the next 9 children to enroll will be elementary school students.

Find the measure of the indicated angle to the nearest degree.
Given:
A right triangle with legs 5 units and 6 units.
To find:
The measure of angle opposite of side whose length is 5 units.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
Let [tex]\theta [/tex] be the missing angle. Then, for the given triangle,
[tex]\tan \theta=\dfrac{5}{6}[/tex]
[tex]\theta=\tan^{-1}\dfrac{5}{6}[/tex]
[tex]\theta=39.805571^\circ[/tex]
Round the value to the nearest degree.
[tex]\theta\approx 40^\circ[/tex]
Therefore, the measure of the required angle is 40 degrees.
