Answer:
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].

A new car is purchased for 22300 dollars. The value of the car depreciates at 10.25% per year. What will the value of the car be, to the nearest cent, after 6 years?
Answer:
$11654 approx
Step-by-step explanation:
Given data
Principal amount = 22300 dollars
Rate= 10.25%
time= 6 years
The expression for the decrease is given as
A=P(1-r)^t-----------Note the negative sign is because of the decrease
substitute
A= 22300(1-0.1025)^6
A=22300(0.8975)^6
A=22300*0.5226
A=$11653.98
Hence the new value is $11654 approx

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:
21
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

Y+3= -5(x-1) write the equation in slope intercept form
Answer: The equation in slope-intercept form: [tex]y=-5x+2[/tex]
Step-by-step explanation:
The given equation of a line : [tex]y+3= -5(x-1)[/tex]
The equation of a line in slope -intercept form: y=mx+c, where m= slope , c=y-intercept.
We first use distributive property(a(b+c)=ab+ac) to simplify the given equation, we get
[tex]y+3=-5x+5[/tex]
Subtract 3 from both sides, we get
[tex]y=-5x-2[/tex]
Hence, the equation in slope-intercept form: [tex]y=-5x+2[/tex]

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

At a carnival, you spin a spinner that has four equal-sized sections, each a different color: green, yellow, red, and blue. If you land on green, you win 2 points. If you land on yellow, red, or blue, you lose 1 point. Write the expected value equation.
A= B= C=
D= E= F=
G=
Answer:
A= 4
B= 4
C= -1
D= 4
E= -1
F= 4
G= -1
Step-by-step explanation:
The expected value equation is the probability of something happening multiplied by the amount of times it happens. In this case you have four equal sized sections, so you have a one in four chance to land in any of these sections. A, B, D, and F represent the four for this one in four chance. C, E, and G represent the amount of points you get when you land on those sections, in this case -1

Answer:
D. (+,-)
Step-by-step explanation:
Map it out!
Quadrant I's points will always be (+,+). It is located in the upper right section.
Quadrant II's points will always be (-,+). It is located in the upper left section.
Quadrant III's points will always be (-,-). It is located in the lower left section.
Quadrant IV's points will always be (+,-). It is located in the lower right section.
The x-coordinate and y-coordinate are both negative, which is the right statement. The best choice is B.
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.
