What is the standard form of the equation of a circle whose diameter is 20 units and whose center is (−1,7)?
VARVARA [1.3K]

Answer:

(x + 1)^2 + (y - 7)^2 = 100

Step-by-sep explanation:

Given:

Diameter of circle = 20 units

Center of circle = (-1, 7)

Standard form of the equation of a circle is expressed in the center-radius form as:

(x - h)^2 + (y - k)^2 = r^2,

Where,

h = -1

k = 7

r = ½ of diameter = ½(20) = 10 units

Plug in the values into the equation

(x - h)^2 + (y - k)^2 = r^2

(x - (-1))^2 + (y - 7)^2 = 10^2

(x + 1)^2 + (y - 7)^2 = 100

Pls help! Will mark Branliest!! 50 points for whoever answers!!!!!!
KiRa [710]

Answer: See below

Step-by-step explanation:

Isolate x for x-2y+2z=9

3x=9+2y

x=\frac{9+2y}{3}....(1)

Substitute (1) into the 2nd equation

\begin{bmatrix}-\frac{9+2y}{3}+3y=-4\\ 2\cdot \frac{9+2y}{3}-5y+3z=16\end{bmatrix}

\frac{3\left(-9+7y\right)}{3}=3\left(-4\right)

7y=-3

y=-3/7

Substitute y=-3/7

\begin{bmatrix}3z+\frac{18-11\left(-\frac{3}{7}\right)}{3}=16\end{bmatrix}

\begin{bmatrix}3z+\frac{53}{7}=16\end{bmatrix}

Isolate z by substituting it

3z+\frac{53}{7}=16

\frac{3z}{3}=\frac{\frac{59}{7}}{3}

z=\frac{59}{21}

For x =9+2y/3 substitute z=59/21 and y=-3/7

x=\frac{9+2\left(-\frac{3}{7}\right)}{3}

x=\frac{19}{7}

x=\frac{19}{7},\:z=\frac{59}{21},\:y=-\frac{3}{7}
