Step-by-step explanation:
What is the slope of a line parallel to the line whose equation is 9x – 3y = 81. Fully
reduce your answer.
Answer:
Ok so right now that is in standard form (Ax+by=C) and we want to get this into y=mx+b form so that we can easily identify the slope. To do that we need to get y alone by folowing these steps:
9x-3y=81
9x-9x-3y=81-9x (in this step we are just getting rid of the x's from the left side so we can get y alone but since we subtract x from that side we need to subtract the same amount of x's on the other)
-3y=81-9x
-3y/-3=81-9x/-3 (finally to get y alone we need to divide by a -3. This is because any negative number multiplied or divided by another negative will give us a positive. If we divide by 3 then y will be negative which is incorrect. We have to divide by -3 on each side)\
y=81-9x/-3 -----> y=-27+3x ( in this part we have to divide everything on the right side of the equation by -3 as we did on the left side. 81/-3 = -27 and -9x/-3 = +3x.
our new equation is y=-27+3x although the proper form is y=mx+b.
all we need to do now is flip the 3x and -27 for this equation to match y-mx+b form. M in the equation represents the slope of an equation.
y=-27+3x---> y=3x-27
in this equation 3 is m and m represents the slope. For an line to be parralel to one another they must have the same slope. Therefore the slope of a line parallel to that equation is 3.
Step-by-step explanation:
The Slope of a line parallel to the line whose equation is 9x – 3y = 81 is 3.
What is the Slope of a line?A slope of a line is the change in y coordinate with respect to the change in x coordinate.
Given that the slope of a line parallel to the line whose equation is
9x – 3y = 81
Reducing the Equation in form of y = mx + c, where m is the slope,
9x - 3y = 81
3y = 9x - 81
y = 3x - 27
Since, two line when parallel have equal slope, so the slope of the given line is 3.
Hence, The Slope of a line parallel to the line whose equation is
9x – 3y = 81 is 3.

Brayden is making dumplings. If he uses 3 5
a cup of dough for each dumpling, how much dough does Brayden need to make 9 dumplings?
WELL, considering 3 5 is three fifths, then all you gotta do is multiply 3/5 by 9 to get your answer. Your answer, in decimals, is 5.4!
Hope this helps, if not, comment below please!!!
( ps: if you want me to convert 5.4 to fraction, just let me know! )
Answer:
27/9 or 5 2/9
Step-by-step explanation:
1. If one dumpling is worth 3/5 just multiply the 3 (numerator) by the amount of dumplings Brayden wants to make (9) so you would get the equation 3(9) and the answer is 27.
2. 27 is now the new numerator so put it over 5: 27/5. 27/5 is an improper fraction so the proper way of putting it would be 5&2/9.
3. Brayden needs 27/5 or 5&2/9 cups of dough to make 9 dumplings.

how are translations described mathematically
Answer:
In geometry, a translation is the shifting of a figure from one place to another without rotating, reflecting or changing its size. This is done by moving the vertices of the figure the prescribed number of spaces on a coordinate plane and then drawing the new figure.
Randi shovels and salts her neighbors' driveways and walkways to earn money during the winter months in her town near the Pocono Mountains. She charges $25 dollars per hour because the amount of time she spends shoveling and salting depends on the size of the driveway and walkway.
Randi has to pay for the salt that she uses, which costs her $3.00 per job on average. She also saves $2.00 per job to cover the costs of replacement shovels as needed.
Randi's profit is the total amount of money that she collects from a snow shoveling and salting job that takes t hours minus her costs.
Randi earned a profit of $60.00 on her last snow shoveling and salting job. Write an equation that can be solved to find how many hours Randi spent shoveling and salting to earn a profit of $60.00.Write your answer in the form of an algebraic equation using the math editor. You do not have to solve the equation, but you will need to use your equation to complete the next test question.
Answer:
25t = 65
Step-by-step explanation:
Given that :
Profit earned = $60
Charge per hour = $25
Randy's cost or expenses = $(2 + 3) = $5 per job
Profit = (charge per hour * t) - cost
Where t = time
$60 = ($25 * t) - $5
$60 = $25t - $5
$25t = $65

Solve the equation below.
3+X= -8
Answer:
x = -11
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
First, subtract 3 from both sides of the equation:
3 + x = -8
x + 3 (-3) = -8 (-3)
x = -8 - 3
Simplify:
x = -8 - 3
x = -11
x = -11 is your answer.
