Answer:
See below
Step-by-step explanation:
I can't draw it for you so here are the points. Draw your triangle with them.
From the original triangle, to rotate 180 degrees around the origin, just imagine your are flipping your computer screen upside down which is 180 degrees. To get the coordinates for the points, just make each x and y value the opposite of what the origin is.
Original points ( 2, 1 ) ( 5, -2 ) ( 3, -4 )
Rotated points ( -2, -1 ) ( -5, 2 ) ( -3, 4 )
Anna's current number of points = 225 points.
She danced correctly and earned = 75 points.
And when she danced incorrectly she loses = 30 points.
Note: For dancing correctly earned points will be added and for dancing incorrectly loses points will be subtracted from the total points has in starting.
So, we can setup an expression as
Current points + earned points - loses points
Plugging values, we get
225 +75 -30 Required expression.
Adding 225 and 75, we get 300.
Therefore, 225 +75 -30 = 300-30.
Subtracting 30 from 300, we get
300-30=270.
Therefore, Anna's final score is 270 points.
Answer:
x=-3y+8
Step-by-step explanation:
2x+6y=16
2x=16-6y
2x=-6y+16
x=-6/2y+16/2
x=-3y+8
The equation which is equivalent to 60% of 25 are x • 1.6 = 25, 0.6 • 25 = x and x/25=60//100
Percentages can be expressed as decimals or fractions.
Given the expression 60% of 25, this can b expressed as:
where x is the result of the expression.
Expressing 60% as a decimal will give;
0.6 of 25 = x
0.6 * 25 = x
From the expression 60/100 * 25 = x, this can also be written as:
25 = 100/60 x
25 = 10/6 x
25 = 1.6x
Hence the equation which is equivalent to 60% of 25 are x • 1.6 = 25, 0.6 • 25 = x and x/25=60//100

Answer:
The answer to your question is: Yes a parabola can be drawn if we know the focus and the directrix.
Step-by-step explanation:
We can say that it is a vertical parabola that opens downwards.
We conclude that if we graph both the focus and the directrix. Also if we continue the process we can find the vertex (-4, -7) and p = 3.
