What is the equation of the circle with center (2, –5) that passes through the point (–2, 10)?
Travka [436]
The standard equation of a circle is

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

where the center is at point (h,k)

From the statement of the problem, it is already established that h = 2 and k = -5. What we have to determine is the value of r. This could be calculated by calculating the distance between the center and point (-2,10). The formula would be

r = square root [(x1-x2)^2 + (y1-y2)^2)]
r = square root [(2--2)^2 + (-5-10)^2)]
r = square root (241)
r^2 = 241

Thus, the equation of the circle is

(x-2)^{2} + (y+5)^{2} =241

What is x in .80x+30=1.20x+14
Sonja [21]

Answer:

x =  40

Step-by-step explanation:

.80x + 30 = 1.20x + 14

<u>-.80x        = -.80x        </u>

          30 = .4x  + 14

        <u>  -14 =         -14</u>

           16 = .4x

            16/.4  = .4/.4x

              40    =  x
