Answer:
Step-by-step explanation:
3 ( y + 8) = 2y - 6
3y + 24 = 2y - 6
3y - 2y = - 6 - 24
y = - 30
Step-by-step explanation:
3y + 24 = 2y -6. subtract 2y from each side
y +24 = -6 subtract 24 from each side
y = -30

Step-by-step explanation:
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.

The student council is organizing a school fair. Council members are making signs to show the prices for admission and for each game a person can play. If the school admission is $2 and the price per game is 25 cents, Let x represent the number of games. Which expression can you use to determine the total amount (in dollars) a person pays for admission and playing x games?
Answer:
$2 + 0.25x
Step-by-step explanation:
The expression would be
Let us assume the x be the number of games
And the school admission is $2 plus the price of game is 25 cents
So, based on the above information
The expression to determine the total amount is
= $2 + 0.25x

I am a bit confused, this is solving systems of equations by elimination.
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

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).
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)
A 10-ft ladder leans against the side of a house. The bottom of the latter is 5 ft from the side of the house. How high is the top of the ladder from the ground. If necessary, round your answer to the nearest tenth.
PLEASE HELP
Answer:
8.7 feet
Step-by-step explanation:
Pythagorean Theorem : 10 is hypotenuse and 5 is opposite. 10^2-5^2=75. Now take 75 and square root it and you will approximately get 8.7.
If x = 10, which equation is true?
A 19 = 2(0.5 - x)
B -28.5 = 3(0.5 - x)
C 3 = 2(x - 0.5)
D 33 = 3x - 3
Answer:
A

Answer:
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

Which equation is correct regarding the measure of ZMNP? O MZMNP = {(x - y) MLMNP = {(x + y) O MZMNP = {(z + y) O MZMNP = {(z-Y)
Step-by-step explanation:
It was correct on edge 2021
The equation that is correct regarding the measure of <MNP is 1/2(x-y)
Circle geometryIn order to determine the measure of m<MNP, we will use the theorem shown below;
The angle at the vertex is half the difference of angles at the intercepted arcs.
The angle at the vertex = m<MNP
angle a the arcs are x and y
Hence;
m<MNO = 1/2 (x - y)
Hence the equation that is correct regarding the measure of <MNP is 1/2(x-y)
