ΔA’B’C’ is a reflection of ΔABC. Which best describes the reflection?
A coordinate plane showing triangles A B C and A prime B prime C prime. The coordinates of the first figure are A negative 2 comma 2, B zero comma 4, and C 2 comma 2. The coordinates of the second figure are A prime 8 comma 2, B prime 6 comma 4, and C prime 4 comma 2.
a.)A reflection over the line x = 2
b.)A reflection over the line y = 3
c.)A reflection over the line x = 3
d.)A reflection over the y-axis
The statement that best describes the reflection of ΔABC is "A reflection over the line x = 3".
What is a triangle?A triangle is a polygon with 3 sides. Also, It has three vertices.
If we plot the two triangles on the graph,
A = (-2,2)
B = (0,4)
C = (2,2)
A' = (8,2)
B' = (6,4)
C' = (4,2)
We will find that the two of the triangles are identical therefore, the two triangles are reflections of each other, and the distance between the points
C and C' is of 2 units, therefore, if we draw the line between the two points, C and C' such that the line is parallel to the y-axis and lies at x=3, then ΔA’B’C’ will be a reflection of ΔABC.
Hence, the statement that best describes the reflection of ΔABC is "A reflection over the line x = 3".

Simplify the following expression.
(2d – 3)(2d – 3)
Answer:
[tex]4d^2-12d+9[/tex]
Step-by-step explanation:
Okay, so lets break this problem down. We are given two binomials to multiply together. The simplest way to get our answer is by using the F.O.I.L method. This is done by the following:
F: First
O: Outer
I: Inner
L: Last
To say simply, the first term in the first parenthesis or 2d will be multiplied the first term in the second parenthesis 2d.
Here are the steps:
[tex](2d-3)(2d-3)\\2d*2d=F\\2d*-3=O\\-3*2d=I\\-3*-3=L\\Now:\\2d*2d=4d^2\\2d*-3=-6d\\-3*2d=-6d\\-3*-3=9\\$4d^2-6d-6d+9\\Combine Terms\\4d^2-12d+9[/tex]

PLS HELP ME ASAP PLS ILL MARK BRAIN
Answer:
Step-by-step explanation:
1). Let the circumference C and area A of the circle are proportional,
C ∝ A
C = kA
Here k = proportionality constant
k = [tex]\frac{C}{A}[/tex]
From the given table,
For C = 25 cm, A = 50 cm²
Then the value of k = [tex]\frac{25}{50}[/tex]
k = [tex]\frac{1}{2}[/tex]
For C = 50 cm, A = 201 cm²
k = [tex]\frac{50}{201}[/tex] ≈ [tex]\frac{1}{4}[/tex]
In both the cases proportionality constant is giving the different values.
Therefore, Circumference and Area of the circular objects are not proportional.
2). If A = [tex]\frac{1}{2}\times r\times C[/tex]
Then this equation will be true for all the values of r and C given in the table.
For r = 4 cm and C = 25 cm
A = [tex]\frac{1}{2}\times 4\times 25[/tex] = 50 cm²
For r = 8 cm and C = 50 cm
A = [tex]\frac{1}{2}\times 8\times 50[/tex]
A = 200 cm²
True for all values of 'r' and 'C'.

Find the simple interest to the nearest cent (round to two decimal places as needed).
$1,295 at 9.25% for 4 years
Answer:
$479.15
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9.25%/100 = 0.0925 per year,
then, solving our equation
I = 1295 × 0.0925 × 4 = 479.15
I = $ 479.15
The simple interest accumulated
on a principal of $ 1,295.00
at a rate of 9.25% per year
for 4 years is $ 479.15.

A player on a school baseball team reaches first base 3 10 of the time he is at bat. Out of 50 times at bat, how many times would you predict he will reach first base?
Answer:
15 times
Step-by-step explanation:
Proportion of times first base is reached = 3 / 10
If Number of times at bat = 50
Number of times first base is reached :
Proportion * Number of times at bats
3/ 10 * 50
(3 * 50) / 10
(150 / 10)
= 15 times

-2 (4 - x) = 12x – 3
(I think this is 9th grade algebra)
Answer:
-1/2
Step-by-step explanation:
-2 (4 - x) = 12x – 3
-8+2x=12x-3
+8 +8
2x=12x+5
-12x -12x
-10x=5
/-10 /-10
= -1/2
Answer:
x = -1/2 or -0.5
Step-by-step explanation:
-2 (4 - x) = 12x - 3
Distribute the -2
-8 + 2x = 12x -3
Add 3 to both sides
-5 + 2x = 12x
Subtract 2x from both sides
-5 = 10x
Divide both sides by 10
x = -1/2 or -0.5

Answer:
15% markdown
Step-by-step explanation:
In order to find the markdown, take the lowered price and place it in a fraction as the numerator, and the initial price as the denominator. This looks like:
[tex]\frac{828.75}{975}[/tex]
with this fraction, we're going to multiply it by 100, with an equation looking like this,
[tex]\frac{828.75}{975}[/tex]×[tex]\frac{100}{1}[/tex]
once we multiply(typically using a calculator, though manually is possible of course) we get 85.
In order to find the markdown price however, we need to subtract 85 from 100, getting 15. This is the markdown price, because it's the percentage of the initial whole that the price went down by. Can check by finding 15% of 975, which is 828.75
