The general form of the equation of a circle is x2 + y2 + 42x + 38y − 47 = 0. The equation of this circle in standard form is .

Readme [11.4K]

Answer:

(-21,-19)

$\sqrt{849}$

Standard form

Step-by-step explanation:

We are given the equation of circle

$x^2+y^2+42x+38y-47=0$

General equation of circle:

$x^2+y^2+2gx+2fy+c=0$

Centre: (-g,-f)

Radius: $\sqrt{g^2+f^2-c}$

Compare the equation to find f, g and c from the equation

$g\rightarrow 21$

$f\rightarrow 19$

$c\rightarrow -47$

Centre: (-21,-19)

Radius (r) $=\sqrt{21^2+19^2+47}=\sqrt{849}$

Standard form of circle:

$(x+21)^2+(y+19)^2=849$

The centre of circle at the point (-21,-19) and its radius is $\sqrt{849}$ .

The general form of the equation of a circle that has the same radius as the above circle is standard form.

H(x) = x + 1 k(x) = x - 2 (h + k)(2) =

barxatty [35]

$h(x) = x + 1$

$k(x) = x - 2$

_________________________________

$(h + k)(x) = h(x) + k(x)$

$(h + k)(x) = (x + 1) + (x - 2) \\$

$(h + k)(x) = x + 1 + x - 2$

$(h + k)(x) = 2x - 1$

$(h + k)(2) = 2(2) - 1$

$(h + k)(2) = 4 - 1$

$(h + k)(2) = 3$

What is the y-value of the solution to the system of equations {3x+4y=42x−4y=6?

timofeeve [1]

The value of y for the system of equation is -1/2 .

<h3>What is a System of Equation ?</h3>

A system of equation is a set of equation that have common solution

The set of equation given is

3x+4y=4

2x−4y=6

To solve the system , Elimination method will be used

Add equation 1 and 2 to eliminate y

5x = 10

x = 2

Substitute the value of x in equation 1 to determine y

3x +4y = 4

6 + 4y = 4

4y = -2

y = -1/2

Therefore the value of y for the system of equation is -1/2 .
