Answer:
D. (x, y) → (x, −y)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.
The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.
The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.
The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.
The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.

The aquarium opened at 8.00 am . In the first hour 140 people purchased admission tickets . In the second hour 25 % more people purchased admission tickets than the first hour . Each ticket cost 15.25 . What was the total amount of money paid for all the tickets purchased in the first two hours please help
Answer:
Total income= $4,083.75
Step-by-step explanation:
First, we need to calculate the total number of people that enter the aquarium in the first two hours.
1st hour= 140
2nd hour= 140*1.25= 175
Total number of people= 315
Now, we can determine the total amount of money earned:
Each ticket cost 15.25.
Total income= 315*15.25
Total income= $4,083.75

10. 156.25/6.25= 25 hrs
Answer:
9. x = 7, y = 10
Step-by-step explanation:
9. I first set up an equation x+y=17
then I set up a second equation y = x+3
I substitute y for x+3 and get x+x+3=17 or 2x+3=17
then I just evaluate the equation x=7
I then use my first equation x+y = 17 and substitute the value 7+y= 17 and get y = 10
10. Just divide 156.25 with 6.25 to get the number of hours she had to work to get 156.25 dollars. The answer would be 156.25/ 6.25 = 25

The normal price of a bicycle is £120
In a sale, there is 1/5 off the normal price of the bicycle.
Work out the price of the bicycle sale?
Answer:
76
Step-by-step explanation:
100% = 120
1/5 of 100% = 20%
20% = 120÷100×20
= 24
100-24= 76
Two different linear functions are shown below with two points given from each function. Use slope-intercept form or point-slope form to find the equation of each. Linear Function A Points: (–5, –2), (–5, 7) Linear Function B Points: (7, –5), (–2, –5) Function A has a slope of -7a slope of 0a slope of 9no slope. The equation of line A is x = -5y = -5x = -2y = 7. Function B has a slope of -7a slope of 0a slope of 9no slope. The equation of line B is x = -5y = -5x = -2y = 7.

Sofia said, "I'm thinking of a fraction that is equivalent to 5 6 . The numerator is 4 less than the denominator." What fraction is Sophia thinking of?
Answer: 20/24
Step-by-step explanation:
Let the denominator be x
The numerator is 4 less than the denominator. Therefore, numerator = x-4.
We can then use the information given in the question as:
5/6 = x-4/x.
Cross multiply.
5 × x = 6(x-4)
5x = 6x - 24
6x - 5x = 24
x = 24
Since the denominator is 24, the numerator will be: = x - 4 = 24 - 4 = 20
Then, the fraction will be 20/24

Y intercept: 35
Slope: 15
This means that it has an independent cost of $35 and a variable fee of 15
Step-by-step explanation:
It's near impossible for me to show you where the line goes and so I'm just going to give you five or so points
To get the 5 point just plug different x values in
(0,35)
(1,50)
(2,65)
(3,80)
The slope intercept equation looks like the following
y=mx+b
where b is the y intercept and m is the slope
this means our equation's slope is 15 and the y intecept
is 35

I need 110g of flour to make something. A 10kg (22lb) bag of four is $12. How much does that 110g cost?
Answer:
Cost of 110 g bag = $ 0.132
Step-by-step explanation:
As we know ,
1 kg = 1000 g
⇒1000 g = 1 kg
⇒1 g = [tex]\frac{1}{1000} = 0.001[/tex] kg
⇒110 g = 110 (0.001) kg = 0.11 kg
⇒110 g = 0.11 kg
Now,
Cost of 10 kg bag = $12
⇒Cost of 1 kg bag = [tex]\frac{12}{10} = 1.2[/tex]
⇒Cost of 1 kg bag = $ 1.2
⇒Cost of 0.11 kg bag = $ (0.11)(1.2) = $ 0.132
∴ we get
Cost of 110 g bag = $ 0.132
