2. In the equation 5(x - 3) = 25, what should you do after using the Distributive Property?​
son4ous [18]

Answer:

umm... This how I learned from the chapter simple equation. Hopefully helps

Step-by-step explanation:

5(x - 3) = 25  we have to find the value of 'x'

so transpose 5 x to the other side = (x - 3) = 25 divided by 5 becuz it was multiplication on the other side so it is equal to = (x - 3) = 5

Now we transpose -3 which is equal to = x = 5 + 3 = 8

so, <u>x = 8</u>

<u />

<u>hopefully it helps!!!!!!!</u>

A circle is centered at the point (5,-4) and passes through (-3,2). The equation of this circle is (x+___)²+(y+___)²=____.
JulsSmile [24]
The equation of a circle is:
 (x-h)^2 + (y-k)^2 = r^2
 where (h,k) is the location of the center and r is the radius.  So we need to find h, k, and r.  The center is given as (5,-4) so h = 5 and k = -4:
 (x-5)^2 + (y-(-4))^2 = r^2
 (x-5)^2 + (y+4)^2 = r^2
 So we need to find r.  Use the distance formula to find the distance between (5,-4) and (-3,2):
 r = [(5-(-3))^2+((-4)-2)^2]^1/2
 r = [8^2 + (-6)^2]^1/2
 r = [64 + 36]^1/2
 r = 100^1/2
 r= 10
 The final equation is:
 (x-5)^2 + (y+4)^2 = 10^2
