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].
The graph of this function is presented in the attachment.

Hey, Can someone help me solve 2x²=63-5x using the quadratic formula. ( In algebra 1 by the way)
Answer (if we're solving for x):
[tex]x=-7[/tex] or [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
Rearrange the terms from [tex]2x^{2} =63-5x[/tex] to [tex]2x^{2}=-5x+63[/tex]Move the terms to the left side: [tex]2x^{2}-(-5x+63)=0[/tex]Use the "sum-product" pattern: [tex]2x^2+14x-9x-63=0[/tex]Get the common factor drom the 2 pairs:[tex]2x(x+7)-9(x+7)=0[/tex]Rewrite the equation in factored form as [tex](2x-9)(x+7)=0[/tex]Create 2 equations from [tex](2x-9)(x+7)=0[/tex]: [tex]2x-9=0\\x+7=0[/tex]This means that [tex]x[/tex] can either be [tex]-7 (-7+7=0=x+7)[/tex] or [tex]\frac{9}{2} (\frac{8}{2}=4; \frac{9}{2}=4.5)[/tex]Jada walks up to a tank of water than can hold up to 10 gallons.

I need help quick. Please help I don’t understand.
Answer:
C
Step-by-step explanation:
The y-intercept of the line is -4, immediately eliminating D. The two definite points on the graph I could visually confirm were (0,-4) and (1, -1). You had to "rise" 3 units and "run" 1 unit. This is a slope of 3/1 or 3. In y=mx+b form, The equation is f(x)=3x-4 or C.

HELP PLEASE!!
Answer:
x = 16
Step-by-step explanation:
hypotenuse= a /sin(α)
= 22.62742
= 16√2
So using this to calculate x:
x = √c2 - a2
= √22.627416997972 - 162
= √256
= 16
Hope this helps you :)
Solve the following equation for y, and then identify the slope of the line: 5x + 9y = 8.
Answer:
equation: y=-5/9(x)+8/9 slope: y=-5/9(x)
Step-by-step explanation:
9y=8-5x
y=(8/9)-(5/9)x
y=-5/9(x)+8/9
State the slope and y-intercept of the graph of y = 1/5 x – 7
If the sales price of a surfboard is $595 and the sales tax rate is 8%. Which of these represents the amount of the sales tax?

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
