Solve for y
6x+2y=12
Answer:
y = -3x +6
Step-by-step explanation:
You want to solve the equation 6x +2y = 12 for y.
SolutionWe can isolate the y-term by subtracting 6x from both sides.
6x -6x +2y = -6x +12
2y = -6x +12 . . . . . . . . . . simplify
Then we can get y by itself by dividing both sides by 2:
2y/2 = -6x/2 +12/2
y = -3x +6 . . . . . . . . . . . simplify
The expression for y is y = -3x +6.

"If you subtract 18 from my number and multiply the difference by -6, the result is -84."
What is Peter's number?
I already made the equation, I just am struggling solving it
-6(x-18)=-84
Answer:
x = 32
Step-by-step explanation:
-6(x-18) = -84
Divide both sides by -6
x - 18 = 14
Add 18 to both sides

Question 4
Answer: Alternative C - 0
Step-by-step explanation:
Since x→∞, we can substitute the values of x for values as 10, 100, 1000 and see the tendency of the function when the values are getting higher (closer to ∞):
For x = 10
f(10) = 0.5*10^(-3/4)
f(10) = 0.089
For x = 100
f(10) = 0.5*100^(-3/4)
f(10) = 0.016
For x = 1000
f(10) = 0.5*1000^(-3/4)
f(10) = 0.003
As we can see, when the x-values are getting closer to infinite, the y-values tends to zero. Thus, alternative C is correct.
A plumber has a 2.5 metre long copper wire. he needs to cut lengths of 60cm, 35cm and 90cm work out how much of the initial 2.5 metre long pipe is left. give your answer in cm
By the concept of measurement of length we get the remaining length of the pipe 65 cm.
The total length of pipe before it was used by the plumber was 2.5 metre = (2.5 x 100)cm = 250cm.
Since,the plumber needs to cut lengths of 60cm, 35cm and 90cm
Thus,total Length of the pipe cut by the plumber = 60cm + 35cm + 90cm = 185cm
After subtracting the length of pipe used by the plumber from the original length of the pipe, we get,
The remaining length of the pipe = 250 - 185 = 65cm
Hence, the remaining length of the pipe is 65 cm.

Gwen says that the sum of -1 3/4 and 2 1/2 is the same as the difference between 2 1/2 and 1 3/4 is Gwen correct explain why or why not
The sum of -1 and 3/4 and 2 and 1/2 is the same as the difference between 2 and 1/2 and 1 and 3/4.
First we will convert the mixed fractions into improper fractions.
-1 and 3/4 = -7/4
2 and 1/2 = 5/2
Sum of -1 and 3/4 and 2 and 1/2 = -7/4 + 5/2 = -7/4 + 10/4 = 3/4
Difference between 2 and 1/2 and 1 and 3/4 = 5/2 - 7/4 = 10/4 - 7/4 = 3/4
As both the values equal to 3/4 , we can say that the sum of -1 and 3/4 and 2 and 1/2 is the same as the difference between 2 and 1/2 and 1 and 3/4.

Slope And Rate Of Change
Based on the linear relationship between the ticket numbers and the total cost, the cost of one ticket can be found to be A. $10.50
How to find the cost of one ticket?First, find the rate of change in ticket pricing assuming the number of tickets is x and the total cost is y.
The rate of change is:
= Change in y / Change in x
= (67.50 - 46.50) / (5 - 3)
= $10.50
Then find the y-intercept:
y = Slope(x) + y-intercept
67.50 = 10.50(5) + y-intercept
y-intercept = 67.50 - 52.50
y-intercept = 15
Linear equation is:
Total cost = Rate of change (Tickets) + y-intercept
A single ticket would cost $10.50 which is the rate of change.

d = 12 cm42°Find the area of the green sector.
We will determine the area of the green section as follows:
[tex]A=r^2\cdot\frac{\alpha}{2}[/tex]Here alpha is the angle [In radians] and r is the radius-
*First: We determine the angle:
[tex]\alpha=360-42-180\Rightarrow\alpha=138[/tex]Now, we transform it to radians:
[tex]138\cdot\frac{\pi}{180}=\frac{23}{30}\pi[/tex]*Second: We replace on the equation:
[tex]A=(6)^2\cdot\frac{(\frac{23}{30}\pi)}{2}\Rightarrow A=\frac{69}{5}\pi[/tex]So, the area of the green sector is 69pi/5 square centimeters. [Approximately 43.4 square centimeters]
Answer:
A ≈ 43.4 cm²
Step-by-step explanation:
the area (A) of the green sector is calculated as
A = area of circle × fraction of circle
given d = 12 then r = 12 ÷ 2 = 6 cm
the central angle of the green sector = 180° - 42° = 138°
then
A = πr² × [tex]\frac{138}{360}[/tex] ( simplify fraction by dividing numerator/denominator by 6 )
= π × 6² × [tex]\frac{23}{60}[/tex]
= 36π × [tex]\frac{23}{60}[/tex]
= [tex]\frac{36\\pi (23) }{60}[/tex]

The equation for constant proportionality is y ∝ m .
1760 is a constant of proportionality.
What is meant by constant of proportionality?The ratio of two proportional values at a constant value is the proportionality constant. When either the ratio or the product of two variables results in a constant, the connection between the two is proportional. The ratio between the two stated quantities affects the proportionality constant's value.
The formula y = 1760m describes the relationship between a distance in yards (y) and a similar value in miles (m).
As a result, the graph of the aforementioned equation will be a straight line with a constant slope of 1760 that passes through the origin (0, 0).
As a result, a measurement in yards and a measurement in miles have the same proportionality relationship.

What is the relation?In mathematics, relations are used to describe the link between the components of two sets. They aid in mapping items from one set (known as the domain) to elements from another set (known as the range), resulting in ordered pairs of the form (input, output).
We have been given the rates of time taken by Judy and Sal to complete a puzzle.
Sal's rate is r, as we can see from the table. Judy is said to take 3 hours to solve a puzzle by herself. It barely takes them two hours to work with Sal.
Because Judy completes the task in three hours, the portion of the puzzle finished in one hour is 1/3.

If the coordinates of quadrilateral ABCD are A (-6,2) B (-5,3) C (7,3) D (0,4) and it is translated 4 units down and 3 units right, then the coordinates of the image is A'(-3,-2), B'(-2,-1), C'(10,-1) and D'(3,0)
The coordinates of the quadrilateral ABCD is
A (-6,2) , B(-5,3), C(7,3) and D(0,4)
The quadrilateral is translated 4 units down and 3 units right
After translation
A(x, y)⇒ A(x + a, y +b)
The value of a and b will be positive if the shift is right and up.
The value of a and b will be negative if the shift is left and down.
Therefore
a = 3, b = -4
The coordinates of A' =(-6+3,2-4)=(-3,-2)
The coordinates of B' =(-5+3,3-4)=(-2,-1)
The coordinates of C' =(7+3,3-4)=(10,-1)

What is the Function?Given a collection of inputs X (domain) and a set of potential outputs Y (codomain), a function is more technically defined as a set of ordered pairings (x,y) where x belongs to X and y belongs to Y, with the caveat that there can only be one ordered pair with the same value of x. The function notation f:XY can be used to express that f is a function from X to Y
Adding two functions-
g(a) = a²- 2
h(a) = -3a
Let h(a) be g(a) + h(a)
So h(a) = a² - 2 - 3a.
We can factorize the function into (a-2)(a-1).
