What are the center and radius of a circle defined by the equation x^2+y^2- 6x+ 8y+ 21=0?
Natali5045456 [20]
You have to complete the square. When you do this you get an equation that looks like this: (x-3)^2 + (y+4)^2 = 4. So your center is (3, -4) and your radius is 2. That looks like B to me!!!

I need help I don’t understand
bagirrra123 [75]

Answer:

x=50

Step-by-step explanation:

A= 30+2x

B= x

Supplementary angles are angles that always add up to 180 degrees.

therefore, A + B=180 degrees

30 + 2x + x = 180: Now we solve

<em>30 + 3x =180 </em>

<em>subtract 30 from both sides</em>

3x=150

<em>divide by 3</em>

3x/3 = 150/3

x= 50
