Explanation:
Transformation V reflects over the line y = 0, which is the x axis. All points on the x axis have a y coordinate of zero. Examples are (1,0) and (2,0).
To reflect over the x axis, we flip the sign of the y coordinate. The x coordinate stays the same. Example: The point (1,5) moves to (1,-5).
In general the rule is [tex](x,y) \to (x,-y)[/tex]
---------------------
Transformation W rotates the point 90 degrees clockwise around the origin (0,0). The rotation rule is [tex](x,y) \to (y,-x)[/tex].
For example, the point (1,7) rotates to (7,-1) when doing a 90 degree clockwise rotation around the origin. We move from the northeast quadrant to the southeast quadrant.
As you can see, we swap the x and y coordinates. Then we do a sign flip on the new y coordinate.
----------------------
Transformation X combines the two previous transformations. We do V first then W next. The order is important (see the next section as to why).
We're given the point (g,h) where we don't know g nor h.
The x axis reflection rule has us get to (g, -h) because we simply flip the y coordinate from positive to negative, or vice versa.
Then applying transformation W has us get to (-h, -g) as the final answer.
----------------------
As stated earllier, the order of the transformations is important. Let's say we did W first and then V next.
Apply transformation W to go from (g,h) to (h,-g)Apply transformation V to go from (h,-g) to (h,g)The point (h,g) is different from (-h, -g) showing that the order does affect where the final point ends up.
However, some transformations can be composited together without worrying about the order. An example could be having a translation followed by another different translation.

Answer:
r = 6.998 in
D = 13.996 in
C = 43.9697 in
Step-by-step explanation:
Area = π[tex]r^2[/tex]
153.86 = π[tex]r^2[/tex]
153.86/π = [tex]r^2[/tex]
sq root(153.86/π) = r ≈ 6.998 in
Diameter = 2r
D = 2(6.998) = 13.996 in
Circumference = 2πr
C = 2π(6.998)
C = 13.996π ≈ 43.9697 in

2x + 5 = 21
[tex]2x + 5 = 21[/tex]
Subtract both sides 5
[tex]2x + 5 - 5 = 21 - 5[/tex]
[tex]2x = 16[/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{16}{2} \\ [/tex]
[tex]x = 8[/tex]
Answer:
8
Step-by-step explanation:
To determine the value of "x", we need to isolate the "x" variable completely. The first step in isolating the variable is to remove the constant on the L.H.S. This can be done by subtracting 5 both sides.
⇒ [tex]2x + 5 = 21[/tex]
⇒ [tex]2x + 5 - 5 = 21 - 5[/tex]
⇒ [tex]2x = 16[/tex]
The last step in isolating the "x" variable is to isolate the cooeficient of x. This can be done by dividing the cooeficient of x both sides.
⇒ [tex]2x = 16[/tex]
[Cooeficient of x is 2]
⇒ [tex]\frac{2x}{2} = \frac{16}{2}[/tex]
⇒ [tex]x = \frac{16}{2} = 8[/tex]
In conclusion, the value of the "x" variable is 8.

7. What is the area of the white border?
8 cm
2 cm
9 cm
15 cm
What is the area of the white border
Answer:
119 cm^2
Step-by-step explanation:
To find the area of the white border, simply find the area of the outside rectangle and subtract the middle(dark) rectangle's area from that value.
White rectangle: 15x9 = 135
Dark rectangle: 8x2 = 16
135 - 16 = 119 cm^2

The area of the considered parallelogram RTSU is given by: Option A: 21 sq. units
How to find the area of a parallelogram?Area of a parallelogram = (its height × its base) sq. units.
What is the distance between two points ( p,q) and (x,y)?The shortest distance(length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units[/tex]
For this case, the missing diagram is attached below.
If we take the base as ST then as ST is parallel to y axis, the line perpendicular to ST would be parallel to x axis. The heigth of a parallogram is the perpendicular distance between its base and top.
The base is ST and top is RU, the line segment US is perpendicular to both RU and US and its length,therefore, will serve as height as its length=perpendicular distance between the base and the top of the parallelogram.
Thus, we get:
Area of RTSU = Length of ST × Length of US
The coordinates of endpoints of ST are (4,-1), (4,-4)
Thus, the length of ST = distance between S and T = [tex]\sqrt{(4-4)^2 + (-1 - (-4))^2 }= 3[/tex]
The coordinates of endpoints of US are (-3,-1), (4,-1)
Thus, the length of US = distance between U and S = [tex]\sqrt{(-3-4)^2 + (-1 - (-1))^2 }= 7[/tex]
Thus, Area of RTSU = Length of ST × Length of US = 3 × 7 = 21 sq. units.
Thus, the area of the considered parallelogram RTSU is given by: Option A: 21 sq. units

Calculate the down payment percent using the following information:
Purchase price: $281,700.00
Closing costs: 2.4% of purchase price
Total move-in costs: $57,466.80
18.0%
20.4%
21.0%
23.5%
18.0% which is the same as 18%
==========================================================
Work Shown:
p = purchase price = $281,700
c = closing costs
c = 2.4% of purchase price
c = 0.024p
c = 0.024*(281,700)
c = 6,760.80
d = unknown down payment amount
m = total move in costs = $57,466.80
m = d + c
d = m - c
d = 57,466.80 - 6,760.80
d = 50,706
down payment percent = d/p = (50,706)/(281,700) = 0.18 = 18%
18% of the purchase price is the down payment.

Answer:
X = 2
AB = 39
CB = 27
Step-by-step explanation:
Since it's a parallelogram (two pairs of parallel sides), we can set each opposite side equal to each other. We know the equation for two opposite sides, side AD and side CB, therefore:
[tex]AD=CB\\14x-1=9x+9\\5x=10\\x=2[/tex]
Now that we know x, we can solve the other equations:
[tex]12x+15=AB\\12*2+15=AB\\24+15=AB\\39=AB[/tex]
And:
[tex]9*2+9=CB\\18+9=CB\\27=CB[/tex]

The total number of balls in a bag will be 4 in which 3 balls are red and 1 ball is blue.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
The probability of the event is 3/4.
Let the total number of balls be 4 of two colors that are red and blue and the probability of red color be 3/4.
There will be a total of 4 balls in the bag, 3 of which will be red and 1 blue.

Let C represent his position from where he went to east direction.
Let H represent his position from where he went to left towards Florida Avenue.
We are given that;
FC = 0.75 miles
CH = 1.2 miles
∠FCH = 90°(This can be deduced from the question)
By Pythagoras theorem, we have;
FH = √(0.75² + 1.2²)
FH = 1.42

Part B
Use the equation you wrote to determine how much money they’ll make if they sell an additional 22 muffins
Answer:
A) $ = 2m + 26
B) $70
Step-by-step explanation:
For a, I know they already sold 13 for $2, meaning they made $26. I know that for each muffin, they will make $2, meaning 2m + 26.
