Answer:
(a) A'(-2, 1), B'(-4, -3), C'(-7, 0)
Step-by-step explanation:
If X is the center of rotation, the coordinates of point P are transformed like this:
P' = -(P -X) +X
P' = 2X -P
(x, y) ⇒ (2(-5) -x, 2(3) -y)
(x, y) ⇒ (-10-x, 6-y)
__
Your points are transformed to ...
A(-8, 5) ⇒ (-10-(-8), 6-5) = A'(-2, 1)
B(-6, 9) ⇒ (-10-(-6), 6-9) = B'(-4, -3)
C(-3, 6) ⇒ (-10-(-3), 6-6) = C'(-7, 0)
These coordinates match the first choice.

B. The population for the survey is all people who surf at Breakers Point.
C. Micah will not get a representative sample.
D. Micah's sample will be representative because anyone can surf at Breakers Point
Answers
Answer: B I think I hope it helps
Step-by-step explanation:
The statements that are true are:
The population for the survey is all people who surf at Breakers Point.Micah will not get a representative sample.What is random sampling?It is a method of selecting a set number of essential items from a given population.
Each item has an equal likelihood of getting chosen.
A. Micah will interview as many surfers as possible to obtain a random sample.
This statement is not always true because Micah may not be able to speak with all of the surfers at Breakers Point during the time frame specified. Also, randomly selecting surfers would result in a more accurate picture of the population.
B. The survey's population consists of all Breakers Point surfers.
This remark is correct, as the demographic of interest at Breakers Point is surfers.
C. Micah will not be able to obtain a representative sample.
This assertion is also correct, as the poll is only done between 8:00 a.m. and 12:00 p.m., which may not be representative of all Breakers Point surfers.
Furthermore, if Micah only polls surfers in a specific place or time period, the sample may be biased.
D. The statement is not always true because not all surfers surf at the same time or location, or have the same level of experience or surfboard preference.

The total interest on a 5 year 5.2% loan with a principal of $10,000 is 10,000 × 0.052 × 5 = $2,600.
True or False?
Answers
Answer:
True
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.2%/100 = 0.052 per year,
then, solving our equation
I = 10000 × 0.052 × 5 = 2600
I = $ 2,600.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 5.2% per year
for 5 years is $ 2,600.00.

Step-by-step explanation:
The value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.
What is Expression?An expression is combination of variables, numbers and operators.
1. The given equation is x /45 = 3
Now value of x is 45×3
x=135
3. The expression is −5.8 + (−2.5)
−5.8 −2.5
The value of expression is -8.3
4.To find the sale price after a 20% discount, we need to subtract 20% of the original price from the original price:
20% of $399 = (20/100) x $399 = $79.80
Sale price = $399 - $79.80 = $319.20
Therefore, the sale price is $319.20.
5. The side length of cube is 5 cm
Volume = 5³
=125 cubic centimeter
6. y = 8/ x equation represents a proportional relationship
7. 5 ft² is area of the wall will the game board cover
9. The given expression is 5 /8 x 4 /5
20/40
1/2
Hence, the value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.

A number is 12 more than the other. Find the numbers if their sum is 48
Answers
Answer:
let one number be x and the other be x + 12
sum = 48
x + x + 12 = 48
2x + 12 = 48
2x = 48 - 12
2x = 36
x = 36 by 2
x = 18
therefore x = 18 and x+12= 18+12=30
so the answer is 18 and 30

Answer:

Step-by-step explanation:
A + B +C = 180
75+51 + C =180
126 +C =180
C = 180-126 = 54
DCB : ACD = 2:1
DCB = 2x
ACD = x
2x+x=54
3x = 54 ; x = 54/3 = 18
DCB = 2x = 2 x 18 = 36
dcb + dbc + bdc = 180
51 + 36 + bdc = 180
87 + bdc = 180 ; bdc = 180 - 87 = 93
I hope im right!!
Answer:
the answer is 93°
Step-by-step explanation:
As you know that in a triangle,
angle1+angle2+angle3 = 180°
hence,
angle ABC + angle BAC + angle DCB + angle ACD ( Angle DCB + angle ACD = angle BCA) = 180°
75°+51°+2x+1x (let the ratio be x) = 180°
126°+3x = 180°
3x = 54°
x = 18°
2x = 36° = angle DCB
In triangle DCB,
51°+36°+angle BCD = 180°
angle BCD = 180°- 87°
Hence, angle BCD = 93°

Alto and Brian both ordered the same size pizzas and Marco's Pizza;
however, they ordered different toppings. Marco's charges an additional
fee for toppings, but all toppings cost the same. Alto got pepperoni,
banana peppers, and black olives on his pizza for a cost of $15.74. Brian
order mushrooms and eggplant of his pizza and paid $14.49. Using this
information, write an equation for the cost of a pizza, C, as a function of
the toppings, t, ordered. *Hint: slope intercept form and you will need the
slope formula
Answers
Answer:
Cost of pizza = 1.25x + 11.99
Step-by-step explanation:
Since Toppings cost the same and the pizza orders are of same size :
Alto ordered for 3 Toppings + pizza = 15.74
Brian ordered for 2 toppings + pizza = 14.49
Hence the cost per topping and pizza could be found :
Cost per topping :
15.74 - 14.49 = 1.25
Hence, slope = 1.25
The intercept, c represents the cost of pizza alone :
Cost of pizza + 2 Toppings = 14.49
Cost per topping = 1.25
Cost of pizza = 14.49 - 2(1.25)
Cost of pizza = 14.49 - 2.50 = 11.99
Expressing in slope - intercept form :
y = mx + c
m = slope ; c = intercept
Cost of pizza = 1.25x + 11.99
