Answer:
5y - 2x = 0
Step-by-step explanation:
Equation of line is given by,
y - y1 = ( x - x1 ) ( y2 - y1)/ (x2 - x1 )
y - 0 = ( x - 0 ) ( 2 - 0 )/ ( 5 - 0 )
y = 2x /5
5y = 2x
5y - 2x = 0
This is the required equation.

Answer:
(0,-1)
Step-by-step explanation:
x point is 6, and the translation is x - 6
6 - 6 = 0
x = 0
y point is 0 and translation is y - 1
0 - 1 = -1
y = -1
Coordinates are (0,-1)
If my answer is incorrect, pls correct me!
If you like my answer and explanation, mark me as brainliest!
-Chetan K
======================================================
Explanation:
The given translation rule will have us do two things (in either order)
Subtract 6 from the x coordinateSubtract 1 from the y coordinateThe given point is P(6,0). So x = 6 and y = 0 here.
Since x = 6, we then have x-6 turn into x - 6 = 6-6 = 0
Because y = 0, we have y-1 turn into y-1 = 0-1 = -1
So that's how (6,0) moves to (0,-1)
-----------------
Or you could write out the steps like this
[tex](x,y) \to (x-6,y-1)\\\\(6,0) \to (6-6,0-1)\\\\(6,0) \to (0,-1)\\\\[/tex]

Explanation:
The degree of separation from the two cities is 30-7 = 23 degrees.
Let's say the point C is at the center of the earth. This would mean angle BCA is 23 degrees.
Any longitude line helps form what is known as a great circle or orthodrome. This is a math term that describes a circle that is centered at the same location as the sphere's center. Imagine that you can wrap a string around the earth and this string only follows this particular longitude line. This string is effectively a vertical equator in a way. The question is: what is the length of this string?
Well that would be the circumference of the circle with radius 3960 miles because the longitudinal circle has the same radius as the sphere.
That approximates to...
C = 2*pi*r
C = 2*pi*3960
C = 24,881.4138164311
C = 24,881.41
So a bit less than 25 thousand miles. I used the calculator's stored version of pi rather than something like 3.14 to get the best accuracy possible. This is the full string's length if we want to travel the entire distance around the globe but stay entirely on this particular longitude line
We don't want the full string's length. Instead, we want just a fractional portion of it. Specifically, we want 23/360 of it because of the central angle of 23 degrees. This will give us the distance between the two cities.
So (23/360)*24,881.4138164311 = 1,589.64588271642
This then rounds to 1589.65 when rounding to the nearest hundredth.
The distance between the two cities is approximately 1589.65 miles
This is comparable to the driving distance from Los Angeles, CA to Houston, TX (approximately 1547 miles).

-(8-2n)=8-2(12-3n)
Answer:
n = 2
Step-by-step explanation:
2n - 8 = -2 (-3n + 12) + 8
2n - 8 = -(-6n + 24) + 8
2n - 8 = 6n - 24 + 8
2n - 8 = 6n - 16
-4n = -8
Divide each side by 4
n = 2
Answer:
n = 2
Step-by-step explanation:
Hi there!
We are given -(8-2n)=8-2(12-3n), which is an equation containing variables, and we want to solve the equation for the variable, which is n.
To do that, we want to isolate n on one side
This equation needs to be solved by the order of operations (PEMDAS, or parentheses, exponents, multiplication, division, addition, subtraction).
First, working from left to right, open up the parentheses on the left side by multiplying both 8 and -2n by -1 (the negative sign in front of the parentheses indicates -1(8-2n), or (8)(-1) + (-1)(-2n))
-1*8=-8
-1*-2n=2n
-8+2n = 8-2(12-3n)
Now on the right, it seems like we should subtract 2 from 8, then multiply the result by (12-3n), but remember we still have parentheses to deal with.
So multiply both 12 and -3n by -2, then add the numbers together
12*-2=-24
-3n*-2=6n
-24+6n
Remember that we didn't do anything to 8, so the equation so far is:
-8+2n=8-24+6n
Now we can start to isolate n on one side (leave n by itself on one side)
Remember we're still working from left-right
So remove -8 from the left by adding it to both sides (-8+8=0)
-8+2n=8-24+6n
+8 +8
_______________________
0 + 2n=16-24+6n
Now we can subtract 24 from 16
0 + 2n = -8 + 6n
Now, we still have 6n on the right, and remember; we want to isolate n on one side.
So let's remove it from the right by subtracting 6n from both sides
0 + 2n = -8+6n
-6n -6n
_________________
-4n = -8
Now we have the expressions containing variables on the left and the numbers on the right. However, remember we just want a singular n by itself, not -4n.
A singular n is also 1n, since 1 * any number = that number
So divide both sides by -4 to find what the value of 1n is
n = 2
Hope this helps!

Coordinate geometry is the use of a 2D plane to represent points.
The transformation is a rotation of 270 degrees clockwiseThe transformation preserves length because the length of the image and preimage are the sameThe transformation preserves angles because the angles of the image and preimage are the sameGiven that:
[tex]A = (-5,5) \to A' = (5,5)[/tex]
[tex]B = (-2,2) \to B' = (2, 2)[/tex]
[tex]C = (-3,2) \to C' = (2,3)[/tex]
By observing the pattern of transformation, the rule is:
[tex](x,y) \to (y,-x)[/tex]
Hence, the transformation is a rotation of 270 degrees clockwise
The length is calculated using the following distance formula:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
So, we have:
[tex]AB = \sqrt{(-5 - -2)^2 + (5 - 2)^2} =\sqrt{18[/tex]
[tex]BC = \sqrt{(-2 - -3)^2 + (2 - 2)^2} =1[/tex]
[tex]AC = \sqrt{(-5 - -3)^2 + (5 - 2)^2} =\sqrt{13[/tex]
And
[tex]A'B' = \sqrt{(5 -2)^2 + (5 - 2)^2} =\sqrt{18[/tex]
[tex]B'C' = \sqrt{(2 - 2)^2 + (2 - 3)^2} =1[/tex]
[tex]A'C' = \sqrt{(5 - 2)^2 + (5 - 3)^2} =\sqrt{13[/tex]
By comparing the lengths of the image and the preimage, we can conclude that the transformation preserves length.
The measure of the angles is calculated as follows:
[tex]a^2 = b^2 + c^2 -2ab \cos A[/tex]
So, we have:
[tex]18 = 1 + 13 -2 \times 1 \times \sqrt{13} \cos C[/tex]
[tex]18 - 1 - 13= -2 \times 1 \times \sqrt{13} \cos C[/tex]
[tex]4= -2 \times 1 \times \sqrt{13} \cos C[/tex]
[tex]-2= \sqrt{13} \cos C[/tex]
Make cos C the subject
[tex]\cos C = -0.5547[/tex]
[tex]C = cos^{-1}(-0.5547)[/tex]
[tex]C = 124^o[/tex]
Also, we have:
[tex]\frac{a}{\sin A} =\frac{c}{\sin C}[/tex]
So, we have:
[tex]\frac{1}{\sin A} =\frac{\sqrt{18}}{\sin( 124)}[/tex]
[tex]\frac{1}{\sin A} =5.1175[/tex]
Rewrite as:
[tex]\sin A = \frac{1}{5.1175}[/tex]
[tex]\sin A = 0.1954[/tex]
[tex]A = \sin^{-1}(0.1954)[/tex]
[tex]A = 11^o[/tex]
Also, we have:
[tex]A + B + C = 180^o[/tex] --- sum of angles in a triangle
[tex]11 + B + 124 = 180^o[/tex]
Collect like terms
[tex]B = 180 -11 - 124[/tex]
[tex]B = 45[/tex]
Hence:
[tex]\angle A = 11[/tex] [tex]\angle B = 45[/tex] and [tex]\angle C = 124[/tex]
