Answers
Answer:
do you still need help?
Step-by-step explanation:
In geometry, transformations are used to move a point or points from one position to another.
Points A, C and D after [tex]90^o[/tex] clockwise rotation are: [tex]A' =(7,-2)[/tex], [tex]C' = (1,-7)[/tex] and [tex]D' = (1,-2)[/tex]Points A and B after [tex]270^o[/tex] clockwise rotation are [tex]A' = (-7,2)[/tex] and [tex]B' = (-7,7)[/tex].Points B and C after [tex]180^o[/tex] clockwise rotation are [tex]B = (-7,-7)[/tex] and [tex]C' = (-7,-1)[/tex].Points A and D after [tex]180^o[/tex] counterclockwise rotation are [tex]A = (-2,-7)[/tex] and [tex]D = (-2,-1)[/tex].Points C and D after [tex]90^o[/tex] counterclockwise rotation are [tex]C' = (-1,7)[/tex] and [tex]D' = (-1,2)[/tex].Point B after [tex]90^o[/tex] clockwise rotation is [tex]B = (7,-7)[/tex]From the plane, we have the following coordinates:
[tex]A = (2,7)[/tex]
[tex]B = (7,7)[/tex]
[tex]C=(7,1)[/tex]
[tex]D = (2,1)[/tex]
When a point is rotated [tex]90^o[/tex] clockwise, the rule is:
[tex](x,y) \to (y,-x)[/tex]
So, the new points after A, C and D are rotated [tex]90^o[/tex] clockwise are:
[tex]A' =(7,-2)[/tex]
[tex]C' = (1,-7)[/tex]
[tex]D' = (1,-2)[/tex]
When a point is rotated [tex]270^o[/tex] clockwise, the rule is:
[tex](x,y) \to (-y,x)[/tex]
So, the new points after A and B are rotated [tex]270^o[/tex] clockwise are:
[tex]A' = (-7,2)[/tex]
[tex]B' = (-7,7)[/tex]
When a point is rotated [tex]180^o[/tex] clockwise and counterclockwise, the rule is:
[tex](x,y) \to (-x,-y)[/tex]
So, the new points after B and C are rotated [tex]180^o[/tex] clockwise are:
[tex]B = (-7,-7)[/tex]
[tex]C' = (-7,-1)[/tex]
And, the new point after A and D are rotated [tex]180^o[/tex] counterclockwise are:
[tex]A = (-2,-7)[/tex]
[tex]D = (-2,-1)[/tex]
When a point is rotated [tex]90^o[/tex] counterclockwise, the rule is:
[tex](x,y) \to (-y,x)[/tex]
So, the new points after C and D are rotated [tex]90^o[/tex] counterclockwise are:
[tex]C' = (-1,7)[/tex]
[tex]D' = (-1,2)[/tex]
Lastly, when a point is rotated [tex]270^o[/tex] counterclockwise, the rule is:
[tex](x,y) \to (y,-x)[/tex]
So, the new point after B is rotated [tex]90^o[/tex] clockwise is:
[tex]B = (7,-7)[/tex]

Twelve Friends go to a movie. Although, They Pay $124.32 for tickets and snacks. they share the cost equally. How much does each person pay? Explain how u got your answer. =)
Answers
Answer:
Answer vary :
each person pays $10.36.
Step-by-step explanation:
‘honestly in my opinion that’s the answer.
we’re trying to find how much each person payed so we have to start by dividing.
-124.32 divided by 12 = 10.36
to find out if it is correct we can multiply 10.36 by how many people are paying.
-10.36 times 12 = 124.32
after multiplying we get the cost of tickets and snacks wich makes it correct.
and that’s how I came to that solution.

Given the equation of the graph, the slope is -1/3 and The two points in the graph are ( 0, 5 ) and ( 3, 4 ).
What is the graph of the equation?Given the equation y = -1/3x + 5
Using the slope intercept form; y = mx + b
Hence,
Slope m is -1/3
y-intercept = ( 0, 5 )
From the equation, y = -1/3x + 5
All lines can be graphed using two points, we select two x values and plug it into the equation; 0 and 3
For x = 0
y = -1/3x + 5 = -1/3(0) + 5 = 5
For x = 3
y = -1/3x + 5 = -1/3(3) + 5 = -(3/3) + 5 = -1+5 = 4
Hence, the slope is -1/3 and The two points in the graph are ( 0, 5 ) and ( 3, 4 ).

what is 3y mean in a math problem
Answers
Answer:
3y means 3 * y
Step-by-step explanation:
I think it is written as 3y instead of 3*y or 3 x y because, 3*y is a bit too cluttered, and 3xy or 3 x y means (Three times X times Y) because X is its own variable.
In other words, 3y means 3 times y
In any of the mathematical problem, the value of 3y will be 3 × y.
What is a mathematical problem?
A mathematical problem is any issue that may be modeled, examined, and potentially resolved using mathematical techniques. This can be a practical issue, like calculating the orbits of the solar system's planets, or a more theoretical issue, like Hilbert's conundrums.
In other cases, such as Russell's Paradox, it can also represent an issue with the very nature of mathematics. Building a mathematical model of the issue is typically the first step in applying mathematics to a real-world situation.
In order to translate the original problem into a mathematical one, it is necessary to abstract from the specifics of the problem, and the modeler must be careful not to lose key features in the process.
Therefore, in any of the mathematical problem, the value of 3y will be 3 × y.
