What is a coordinate system?

When determining the location of points or other geometrical elements on a manifold, such as Euclidean space, a coordinate system in geometry uses one or more numbers or coordinates.

The value of the coordinate x and the value of the coordinate y are both negative in the fourth quadrant's coordinate system.

As a result, it is true to say that both the x- and y-coordinates are negative. The correct response is B.

The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].

The graph of this function is presented in the attachment.

Step-by-step explanation:

The general equation of the circunferece is defined by the following formula:

[tex]x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0[/tex] (1)

We can determine the value of the coefficients by knowing three distinct points: [tex](x_{1}, y_{1}) = (3,0)[/tex], [tex](x_{2},y_{2}) = (5,-2)[/tex], [tex](x_{3},y_{3}) = (1, -2)[/tex]

The system of linear equations is:

[tex]3\cdot A + C = -9[/tex] (2)

[tex]5\cdot A -2\cdot B + C = -29[/tex] (3)

[tex]A -2\cdot B + C = -5[/tex] (4)

The solution of this system is: [tex]A = -6[/tex], [tex]B = 4[/tex], [tex]C = 9[/tex].

The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].

FIND THE LENGTH OF AC

Answers

Answer:

AC=18

Step-by-step explanation:

To find AC, use the Pythagorean Theorem. Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b². 12²-8²=b²

144-64=b²

80=b²

√80=√b²

8.94427191=b

That is for one of the two right triangles that make up the tent. Since there are 2 triangles, 8.94427191 only equals BC or AB. So, multiply 8.94427191×2=17.88854382 to find the length of AC.

Answers

Answer:

This is the exterior angle theorem, so

x+30+x+22=130

2x+52=130

2x=78

x=39

sooooooooooooo

39+22=61 degrees

61 degrees

Answer:

Step-by-step explanation:

First set up the equation

130 + x + 30 + x + 22 = 180 (triangle angles always add up to 180)

then start to solve to find x

130 +2x + 30 + 22 = 180

182 + 2x = 180

-182 -182

2x = -2

/2 /2

x = -1

Then just plug it back into the equation

-1 + 22

Answers

Answer:

x=3

y=1

Step-by-step explanation:

-2x - 7y = -13

3x + 6y = 15

3(-2x - 7y = -13) = -6x - 21y = -39

2(3x + 6y = 15) = 6x + 12y = 30

-6x - 21y = -39

---------------------- The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9

6x + 12y = 30

Therefore, you can say that -9y = -9 so y = 1

FInally, plug that back into either one of the original equations:

3x + 6(1) =15

3x = 9

x = 3
