Step-by-step explanation:

Equation

(x - 8)² + (y + 5)² = 4

Process

1.- Write the standard equation of the circle

(x - h)² + (y - k)² = r²

2.- Find the center

The center are the letters h and k

h = 8 k = -5

3.- Find the radius

r = 2

4.- Graph the circle ( i will use geogebra)

7/7q+21= x /5q^2-45 then x=?

anzhelika [568]

Answer:

x = 5q - 15

Step-by-step explanation:

$\frac{7}{7q+21}=\frac{x}{5q^{2}-45}\\\\\frac{7}{7(q+3)}=\frac{x}{5 (q^{2} -9)}\\\\frac{1}{q+3}=\frac{x}{5*(q^{2}-3^{2})}\\\\\frac{1}{q+3}=\frac{x}{5(q+3)(q-3)}\\\\\frac{1}{q+3}*5*(q+3)(q-3)=x\\\\5(q-3)=x\\\\x= 5q-15$
