The transformations are ...
(x, y) ⇒ (-y, x) . . . . 90° rotation
(x, y) ⇒ (-x, -y) . . . . 180° rotation
(x, y) ⇒ (y, -x) . . . . 270° rotation
Each successive rotation is a 90° rotation from the previous one. This makes writing the formulas in a spreadsheet really easy. The attached shows the transformed coordinates.

Is the expression below completely factored? If not, complete the factorization.
4y(8y3 – 12y2 + 6y)
A) No, because the greatest common factor is 8y?, and the completely factored form is 8y?(4y2 - 6y + 3).
B) Yes, because the greatest common factor is 4y, and the completely factored form is 44(8y3 - 12y2 + 6y).
C) No, because the greatest common factor 4y?, and the completely factored form is 4y?(8y2 - 12y + 6).
D) No, because the greatest common factor is sy, and the completely factored form is 8y(4y3 - 6y2 + 3y).
Answers
Answer:
A) No, because the greatest common factor is 8y?, and the completely factored form is 8y2(4y2 - 6y + 3).
Step-by-step explanation:
Considering the expression
4y(8y3 – 12y2 + 6y)
From the elements in the parenthesis, 2 and y can still be factored out such that what will be left of each element
8y3/2y = 4y2
12y2/2y = 6y
6y/2y = 3
Hence
4y(8y3 – 12y2 + 6y) = 4y*2y(4y2 - 6y +3)
= 8y2(4y2 - 6y + 3)

x = 120 degrees
Step-by-step explanation:
angle below x is 40 degrees because it is a corresponding angle.
x = 180 - 40 - 20 = 120 degrees
Answer:
x=120 I believe
Step-by-step explanation:
so using the left side, we can form the equation x+20+_=180
x+_=160
we know the 2 lines that are parallel, and they have a line through it (idrk what it's called)
_=40
x+40=160
x=120

I am a bit confused, this is solving systems of equations by elimination.
Answers
Answer:
y = -4
x = -2
Step-by-step explanation:
1. Approach
To solve a system by the process of elimination, one wants to manipulate an equation such that when one adds the equations in a system, one of the variables cancels out. The easiest way to do this is to select a variable, then find the LCM (least common multiple) of the two coefficients of the selected variables. Then multiply each of the equations by the respect factor that is needed to get the coefficient of the variable to the LCM. In the event that the cofficients do not have inverse signs, multiply one of the equations by (-1). No all that is left is to add the equations, use inverse operations to solve for the other variable, then back substitute to find the value of the selected varibale.
2.Set up the process
3x - 2y = 2
5x - 5y = 10
Selected variable; x
LCM of the coefficents (3, 5) = 15
Multiply the first equation by 5, and the second by 3
(3x - 2y = 2) *5
(5x - 5y = 10)*3
Resulting system
15x - 10y = 10
15x - 15y = 30
Now, multiply the first equation by (-1) to make the coefficents additive inverses
(15x - 10y = 10) (-1)
15x - 15y = 30
-15x + 10y = -10
15x - 15y = 30
3. Solving
Add the two resulting systems,
-15x + 10y = -10
15x - 15y = 30
_____________
-5y = 20
Inverse operations
-5y = 20
/-5 /-5
y = -4
Back solve
3x - 2y = 2
(3x) - 2(-4) = 2
Simplify,
3x + 8 = 2
Inverse operations,
3x + 8 = 2
-8 -8
3x = -6
/3 /3
x = -2

A tree casts shadow 26 ft long. A 3 ft tall flowers casts a shadow 4 ft long. How tall is the tree?
Answers
Answer:
19. 5 feets
Step-by-step explanation:
Shadow of tree = 26 feets
Height of flower = 3 feets
Shadow of flower = 4 feets
Height of sun Innthe sky:
Shadow of flower / height of flower
= 4/3 = 1.333333
Height of tree:
Shadow of tree / height of sun
26 feets / 1.33333
= 19.5 feets
Hence, height of tree = 19.5 feets

Thus this is an isoceles triangle—> x = y
Using Pythagoras’s theorem, 2x^2 = 7^2= 49
Thus x = 7/rt(2) or -7/rt(2) , then reject negative values and rationalise to get 7rt(2)/2 for x, thus x = y = 7rt(2)/2
3x+y=-5
7x+3y=1
I dont know
Answers
Answer:
may be it will help u
Step-by-step explanation:
3x+y= -5
7x+3y= 1
ans wehave to subtract .now
4x-2y=4
either 4x=4 or -2y=4
...×=1 y= -2
3x+y =-5 (times everything by 3)
7x+3y=1 (Times everything by 1)
Because both the signs are + you have to take away that’s a rule.
9x+3y =-15
7x+3y =1
(The 3y cancels out)
2x= -16
x=-8
We then take any equation of the two to find y I picked 7x+3y =1 you substitute the x with -8
7x+3y =1
7x (-8)+ 3y =1
-56+3y=1
(Add 56 to the other side)
3y= 57
y= 19
So x is -8 and y = 19
If you still unsure you can ask me I can explain again
