Answer:
1. ∠A = ∠W
2. ∠B = ∠X
3. ∠C = ∠Y
4. ∠D = ∠Z
Step-by-step explanation:
This is actually a lot more simple than you think!
In order to solve this you must be able to distinguish both of the points from each figure shown in the picture!
In this case, we can see that Figure WXYZ is faced in a upright manner!
While Figure ABCD is in a regular position!
What you want to do is turn either Figure ABCD or WXYZ in to the same position and you will see that the shape, points, and position will be same!
For example:
(This is two separate lines that are in different positions)
A
|
B
C ------ D
If you are to change either in the same position, in this case I'll change
line AB to the same position as CD:
A ------ B
C ------ D
You can see that which points will be corresponding to each other!
(Corresponding means two that are similar or same to each other in characteristics)
So the answer to the example would be:
Point A = Point C
&
Point B = Point D
Back to the original problem, it works the same way:
If you turn figure WXYZ in the same position as ABCD, you will get the answers:
1. ∠A = ∠W (Answer choice: B)
2 ∠B = ∠X (Answer choice: C)
3. ∠C = ∠Y (Answer choice: D)
4. ∠D = ∠Z (Answer choice: A)
You can also see this when they say:
'Figure ABCD is similar to Figure WXYZ'
In means of angles it would look like:
(Figure) ABCD = (Figure) WXYZ
And if you were to separate each letter with the one it corresponds to on the other side, you will see that you will get:
A = W
B = X
C = Y
D = Z

Answer:
D. 25% decrease
Step-by-step explanation:
When we have multiple choice questions, generally the best first step is to narrow down your options. We can see that our options are either increase or decrease. Obviously, if the class read 40 books in June and then 30 in July, that's a decrease. So option C is out of the question.
We still have three options left, so we have to now figure out the exact percentage decrease. Let's find out what percentage of 40 is 30.
[tex]\frac{30}{40}=0.75[/tex]
(Remember that percentages are parts of 1. 100%=1, 50%=.5)
So 30 is 75% of 40. And what percentage did we go down from 100%? 25%.
There was a 25% decrease in the number of books read.
I hope this helps!

g(x)=x^3 - 5x^2 + 7x + 13
Express g(x) as a product of linear factors.
g(x)=
Answers
Answer:
g = 7 + 13x-1 + -5x + x2
Step-by-step explanation:
Simplifying
g(x) = x3 + -5x2 + 7x + 13
Multiply g * x
gx = x3 + -5x2 + 7x + 13
Reorder the terms:
gx = 13 + 7x + -5x2 + x3
Solving
gx = 13 + 7x + -5x2 + x3
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Divide each side by 'x'.
g = 13x-1 + 7 + -5x + x2
Simplifying
g = 13x-1 + 7 + -5x + x2
Reorder the terms:
g = 7 + 13x-1 + -5x + x2
If 3x – 9y = 21 and 6x + 3y = 21, which of these could be a value of x or y?
Answers
Answer: x=4, y=-1
Step-by-step explanation:
Multiply the second equation by 3:
18x+9y=63
Then summarize both equations 18x+9y+3x-9y=21+63
21x=84 => x=4
use x=4 in any of initial equations ,for instance in first one:
3*4-9*y=21
12-9*y=21
9y=12-21
9y=-9
y=-1

The length of a rectangle is 5 inches more than its vedth. The area of the rectangle is equal to
2 inches more than 4 times the perimeter. Find the length and width of the rectangle.
Answers
Answer:
The width = x = 14The length = x+5 = 14+5 = 19Step-by-step explanation:
Let l = length, w = width, A = area = l×w , and P = perimeter = 2(l+w)
Let 'x' be the width
As the length 'l' of a rectangle is 5 inches more than its width.
so the length will be = x+5
As the Area of the rectangle is equal to 2 inches more than 4 times the perimeter.
A = 4P + 2
so the equation becomes
l × w = 4×2(l+w)+2
substituting w=x, l = x+5,
(x+5)x = 8(x+5+x)+2
x²+5x = 8(5+2x)+2
x²+5x = 40+16x+2
x²+5x = 16x+42
x²+5x-16x-42 =0
x²-11x-42=0
[tex]x^2-11x=42[/tex]
[tex]\mathrm{Add\:}a^2=\left(-\frac{11}{2}\right)^2\mathrm{\:to\:both\:sides}[/tex]
[tex]x^2-11x+\left(-\frac{11}{2}\right)^2=42+\left(-\frac{11}{2}\right)^2[/tex]
[tex]x^2-11x+\left(-\frac{11}{2}\right)^2=\frac{289}{4}[/tex]
[tex]\left(x-\frac{11}{2}\right)^2=\frac{289}{4}[/tex]
[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]
solving
[tex]x-\frac{11}{2}=\sqrt{\frac{289}{4}}[/tex]
[tex]x-\frac{11}{2}=\frac{\sqrt{289}}{\sqrt{4}}[/tex]
[tex]x-\frac{11}{2}=\frac{\sqrt{289}}{2}[/tex]
[tex]x-\frac{11}{2}=\frac{17}{2}[/tex]
[tex]x-\frac{11}{2}+\frac{11}{2}=\frac{17}{2}+\frac{11}{2}[/tex]
[tex]x=14[/tex]
similarly solving
[tex]x-\frac{11}{2}=-\sqrt{\frac{289}{4}}[/tex]
[tex]x-\frac{11}{2}=-\frac{17}{2}[/tex]
[tex]x-\frac{11}{2}+\frac{11}{2}=-\frac{17}{2}+\frac{11}{2}[/tex]
[tex]x=-3[/tex]
so
x = 14, or x = -3
As the width 'x' can not be negative.
so x = 14
Thus,
The width = x = 14The length = x+5 = 14+5 = 19I need help can you help me

Explain how you know. Is the point (20,24) on line ℓ? Explain how you know. Is the point (80,100) on line ℓ? Explain how you know.
Answers
Answer/Step-by-step explanation:
First find the equation of the line. The graph is a proportional graph. Hence, the equation would be in the form is y = kx.
Where k I stye constant of proportionality (y/x).
Using a point on the line, (4, 5),
k = y/x = ⁵/4
Substitute ⁵/4 into y = kx.
Thus, the equation of the graph would be:
y = ⁵/4x
Plug in the value of the x and y coordinates of a point into the equation to determine if the point is on line l. If it makes the equation true, then it is a point on the line.
Thus:
✍️For the point, (20, 24), substitute x = 20, y = 24 in y = ⁵/4x
24 = ⁵/4(20)
24 = 5(5)
24 = 25 (NOT TRUE)
✅Therefore, the point, (20, 24) is not a point on line l.
✍️For the point, (80, 100), substitute x = 80, y = 100 in y = ⁵/4x
100 = ⁵/4(80)
100 = 5(20)
100 = 100 (TRUE)
✅Therefore, the point, (80, 100) IS A POINT on line l.
