Based on the graph below, which sequence of transformations is needed to carry ABCD onto its image A'B'CD?
Answer:
The third is correct.
Step-by-step explanation:
Preimage: A(2,3), B(5,6), C(8,6), D(8,3)
Image: A'(-2, 6); B'(-5,3); C'(-8,3); D'(-8,6)
Option 3.
Translation Rotation 180° Clockwise
(x, y-9) (-x,-y)
A(2,3) (2,-6) A' (-2,-6)
B(5,6) (5,-3) B' (-5,3)
C(8,6) (8,-3) C' (-8,3)
D(8,3) (8,-6) D' (-8,6)
Transformation involves changing the position of a shape.
The sequence of transformation is: (d) A translation rule by [tex]\mathbf{(x,y) \to (x, y - 9)}[/tex] and then a 180 degrees clockwise rotation about the origin
The coordinates of the pre-image is:
[tex]\mathbf{A = (2,3)}[/tex]
[tex]\mathbf{B = (5,6)}[/tex]
[tex]\mathbf{C = (8,6)}[/tex]
[tex]\mathbf{D = (8,3)}[/tex]
Of the given sequence of transformations, option (d) is correct.
The proof is as follows.
First, translate ABCD by (x, y - 9)
So, we have:
[tex]\mathbf{(x,y) \to (x, y - 9)}[/tex]
[tex]\mathbf{(2,3) \to (2, -6)}[/tex]
[tex]\mathbf{(5,6) \to (5, -3)}[/tex]
[tex]\mathbf{(8,6) \to (8, -3)}[/tex]
[tex]\mathbf{(8,3) \to (8, -6)}[/tex]
Next, rotate by 180 degrees.
The rule of this transformation is:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
So, we have:
[tex]\mathbf{(2,-6) \to (-2,6)}[/tex]
[tex]\mathbf{(5,-3) \to (-5,3)}[/tex]
[tex]\mathbf{(8,-3) \to (-8,3)}[/tex]
[tex]\mathbf{(8,-6) \to (-8,6)}[/tex]
From the graph, the coordinates of the image are:
[tex]\mathbf{A" = (-2, 6)}[/tex]
[tex]\mathbf{ B" = (-5,3)}[/tex]
[tex]\mathbf{C" = (-8,3)}[/tex]
[tex]\mathbf{D" = (-8,6)}[/tex]
Hence, the sequence of transformation is:
(d) A translation rule by [tex]\mathbf{(x,y) \to (x, y - 9)}[/tex] and then a 180 degrees clockwise rotation about the origin

Which equation is the slope-intercept form of the equation of the line that passes through (1, 2) and is parallel to 4x - 2y = 6?
Answer:
The equation of the parallel line is y = 2x
Step-by-step explanation:
The slope-intercept form of the linear equation is:
y = m x + b, where
m is the slope of the line b is the y-intercept (value y at x = 0)Parallel lines have the same slopes and different y-intercepts
∵ The equation of the given line is 4x - 2y = 6
→ To find the slope of this line re-arrange it to be in the
slope-intercept form Subtract 4x from both sides to move x to
the right side
∵ 4x - 4x - 2y = 6 - 4x
∴ -2y = 6 - 4x
→ Divide both sides by -2 to make the coefficient of y = 1
∵ [tex]\frac{-2y}{-2}=\frac{6}{-2}-\frac{4x}{-2}[/tex]
∴ y = -3 - (-2x)
∴ y = -3 + 2x
→ Swithch -3 and 2x
∴ y = 2x - 3
→ Compare it by the form of the equation above to find m
∴ m = 2
∴ The slope of the given line is 2
∵ The two lines are parallel
∴ The slope of the parallel line is 2
→ Substitute it in the form of the equation above
∴ y = 2x + b
→ To find b substitute x and y in the equation by the coordinates
of any point on the line
∵ The line passes through the point (1, 2)
∴ x = 1 and y = 2
∵ 2 = 2(1) + b
∴ 2 = 2 + b
→ Subtract 2 from both sides to find b
∴ 2 - 2 = 2 - 2 + b
∴ 0 = b
∴ y = 2x
The equation of the parallel line is y = 2x
Jacque needs to buy some pizzas for a party at her office. She's ordering from a restaurant that charges a \$7.50$7.50dollar sign, 7, point, 50 delivery fee and \$14$14dollar sign, 14 per pizza. She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under \$60$60dollar sign, 60. Each pizza is cut into 888 slices, and she wonders how many total slices she can afford. Let P represent the number of pizzas that Jacque buys. ------------------------------------------------------------------------------------ 2) What is the largest number of slices that Jacque can afford?
Answer:
3 pizzas
24 slices.
Step-by-step explanation:
Given:
Delivery fee = $7.50
Charges per pizza = $14
Total money available with Jacque = $60
Number of slices in one pizza = 8
To find:
The number of pizzas, [tex]P[/tex] that Jacque can buy and
The number of slices, that Jacque can afford.
Solution:
Cost of one pizza = $14
Cost of [tex]P[/tex] pizzas = $14 [tex]\times P[/tex]
Out of total money of $60, $7.50 will be used as delivery charge.
Therefore, money that can be used for buying pizza = $60 - $7.50 = $52.50
Now, the money available must be greater than or equal to the cost of [tex]P[/tex] pizzas:
i.e. $52.50 [tex]\geq[/tex] [tex]\$14P[/tex]
[tex]\Rightarrow P = 3[/tex]
A maximum of 3 pizzas can be bought.
Number of slices that Jacque can afford = 3 [tex]\times[/tex] 8 = 24 slices

The graph of the function has zeros of 0 and 3, two distinct real zeros, and no complex zeros.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function.
We have a function:
[tex]\rm y= x^2(x^2 - 6x + 9)[/tex]
We can write it as a:
[tex]\rm y= x^2(x^2 - 2(3)(x)+ 3^2)[/tex]
[tex]\rm y = x^2(x-3)^2[/tex]
To find the zeros equate to the function with the zero.
y = 0
[tex]\rm x^2(x-3)^2=0[/tex]
First, take [tex]\rm x^2= 0[/tex] we get:
x = 0
Now
[tex]\rm (x-3)^2=0[/tex]
x - 3 = 0
x = 3
Thus, the graph of the function has zeros of 0 and 3, two distinct real zeros, and no complex zeros.

Trayvon recorded the number of minutes he spent practicing each (swimming event) over three days. He recorded his times in the table below.
Trayvon’s Swim Practice Times
Monday Wednesday Friday
Backstroke 12.5 min 15.67 min 9.32 min
Butterfly 14.333 min 12.1 min 10.78 min
Which statement explains how to find the event Trayvon spent more time practicing?
A Compare the sum 12.50 + 15.67 + 9.32 = 37.49 to the sum 14.333 + 12.100 + 10.780 = 37.213; he spent more time practicing the backstroke than the butterfly.
B Compare the sum 12.05 + 15.67 + 9.32 = 37.04 to the sum 14.333 + 12.001 + 10.078 = 36.412; he spent more time practicing the backstroke than the butterfly.
C Compare the sum 12.500 + 14.333 = 26.833 to the sum 15.67 + 12.10 = 27.77 and to the sum 9.32 + 10.78 = 20.1; he spent more time practicing on Wednesday than on the other days.
D Compare the sum 12.005 + 14.333 = 26.338 to the sum 15.67 + 12.01 = 27.68 and to the sum 9.32 + 10.78 = 20.1; he spent more time practicing on Wednesday than on the other days.
Answer:
A
Step-by-step explanation:
We have a table listing the number of minutes Trayvon practiced the Backstroke and Butterfly on Monday, Wednesday, and Friday.
We want to find event that Trayvon spent more time practicing.
To do so, we add up all the minutes of one event and compare this to the total minutes of the other event.
Therefore, we can eliminate options C and D. These two options evaluate the time on Wednesday compared to other days, but we want to do is to find which event did Trayvon spend the longest on.
So, let's add up all the minutes spent doing the Backstroke. Trayvon over the course of the three days spent 12.5 mins, 15.67 mins, and 9.32 mins.
Therefore, the total minutes Trayvon spend practicing the Backstroke is:
[tex]12.5+15.67+9.32=37.49\text{ mins}[/tex]
Now, let's add up all the minutes spent doing the Butterfly. Trayvon spent 14.333 mins, 12.1 mins, and 10.78 mins over the course of three days. So, the total time spent doing the Butterfly is:
[tex]14.333+12.1+10.78=37.213\text{ mins}[/tex]
Trayvon spent a total of 37.49 minutes doing the Backstroke and 37.213 minutes doing the Butterfly.
37.49 is greater than 37.213. So, Trayvon spent more time practicing the Backstroke.
So, our correct answer is A.
There are some number and calculation errors in B.
And we're done!
Answer:
C
Step-by-step explanation:
On Monday he spent 12.5 min on backstroke and 14.33 min on butterfly.
He spent 26.83 min practicing at the Monday event.
On Wednesday: 15.67 min on backstroke and 12.1 min on butterfly.
He spent 27.77 min on practicing at the Wednesday event.
On Friday: 2.32 min on backstroke and 10.78 min on butterfly.
He spent 13.1 on practicing at the Friday event.
So, he spent more time at the Wednesday event.

Casey bought a 15.4 pound turkey and an 11.6 pound ham for Thanksgiving and paid $38.51.
Her friend Jane bought a 10.2 pound turkey and a 7.3 pound ham from the same store and paid
$24.84. Find the cost per pound of turkey and the cost per pound of ham.
Answer:
h = 1.74
t = 1.19
Step-by-step explanation:
15.4t + 11.6h = 38.51
10.2t + 7.3h = 24.84
15.4•t + 11.6•h = 38.51
10.2•t + 7.3•h = 24.84
11.6h+15.4t = 38.51
7.3h+10.2t = 24.84
h = 87
50
= 1.74
t = 119

The revenue for a company producing widgets is given by y = -20x2 - 50x + 200, where x is the price in dollars for each widget. The cost for the production is given by y = 30x - 10. Determine the price that will allow the production of widget to break even.
Answer:
The price is x = $2.779
Step-by-step explanation:
From the question we are told that
The revenue is [tex]y = - 20x^2 - 50 x + 200[/tex]
The cost of production is [tex]y = 30 x - 10[/tex]
Generally at break even point the cost of production is equal to the revenue
So
[tex]-20x^2 -50x + 200 = 30x-10[/tex]
=> [tex]20x^2 +20 -210 = 0[/tex]
Using the quadratic formula to solve this equation we have that
x = $2.779

I just did this problem and guessed correctly.
The complex solutions of which equation have a real component of 4 is x² - 8x +16 +21 = 0.
What is Complex number?Complex numbers are numbers that consist of two parts — a real number and an imaginary number.
On solving all equation the correct one is x² - 8x +16 = -21.
Using discriminant method calculating the roots
x² - 8x +16 +21 = 0
x² - 8x + 37 = 0
x= -b ± √b² -4ac / 2a
x= 8 ± √ -8² - 4*1 * (37) /2a
x= 8 ± √- 84 / 2
x= 8 ± √2² *(- 21) /2
x=( 8 ± √2² *√21 i)/2

What is HIV?
HIV Overview
HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome).
There is currently no effective cure. Once people get HIV, they have it for life.
But with proper medical care, HIV can be controlled. People with HIV who get effective HIV treatment can live long, healthy lives and protect their partners.
Where did HIV come from?
History of HIV
HIV infection in humans came from a type of chimpanzee in Central Africa.
The chimpanzee version of the virus (called simian immunodeficiency virus, or SIV) was probably passed to humans when humans hunted these chimpanzees for meat and came in contact with their infected blood.
Studies show that HIV may have jumped from chimpanzees to humans as far back as the late 1800s.
Over decades, HIV slowly spread across Africa and later into other parts of the world. We know that the virus has existed in the United States since at least the mid to late 1970s.
