3x + 12 = -6x - 9 and
Marianna [84]
  • Answer:

<em>1. x = - 7/3 = - 2  1/3</em>

<em>2. x = -2</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em />

<em>3x + 12 = - 6x - 9</em>

<em>3x + 6x = - 12 - 9</em>

<em>9x = - 21</em>

<em>x = - 21⁽³/9</em>

<em>x = - 7/3</em>

<em>x = - 2  1/3</em>

<em />

<em>12x + 20 = 2x</em>

<em>12x - 2x = - 20</em>

<em>10x = - 20</em>

<em>x = - 20/10</em>

<em>x = - 2</em>

<em />

<em>Good luck !</em>

What is the standard form of the equation<br><br>Center (-14,5), circumference: 22π
IRISSAK [1]

The standard equation for a circle with center at (h,k) and radius r is

(x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center of the circle.

The formula for the circumference of a circle is C = 2pi*r.  In this particular problem, we need to determine the radius of the circle.  That radius is:  r = C/[2pi].  Here, C = 22pi, so we get r = 22pi/[2pi], and so r^2 = 11^2.

Putting to use the given info, we have:

(x+14)^2 + (y-5)^2 = 11^2
