2(3x+6) = 3(2x-6) solve equations with variables on both sides

1 answer:

Serjik [45]3 years ago

Answer:

2(3x+6) = 6x+12
3(2x-6) = 6x-18

6x+12=6x-18

Subtract 12 from 18, which gives you:

6x=6x-6

Subtract the 6x on the opposite side of the equal side, and your answer is: x = -6

Where is the center of the circle and what is its radius

Dmitrij [34]

Answer:

(3, -4) and r = 3

Step-by-step explanation:

The center of a circle can be found using the equation $(x-h)^2 + (y-k)^2 = r^2$ and is (h,k) from it. Notice h and k are the opposite value as in the equation.

First write the equation in this form.

$x^2 - 6x + ( ?)+ y^2 +8y + (?) + 16 = 0$

Complete the square with each variable to find what numbers should go in place of the question marks.

$(-6/2)^2 = -3^2 = 9$

$(8/2)^2 = 4^2 = 16$

Since 16 has already been added to the equation, just add 9 to both sides of the equation.

$x^2 - 6x + 9 + y^2 +8y + 16 = 9\\(x-3)^2 + (y+4)^2 = 9$

So the center is (3,-4) and the radius is 3.
