Best ResponseYou've already chosen the best response.0Let's solve for x. (x−5)(2)+(y+3)(2)=25 Step 1: Add 4 to both sides. 2x+2y−4+4=25+4 2x+2y=29 Step 2: Add 2y to both sides. 2x+2y+−2y=29+−2y 2x=−2y+29 Step 3: Divide both sides by 2. 2x2=−2y+292 x=−y+292 Answer: x=−y+29/2 29/2=14.5 14.5/2= 7.25 7.25/2=12.5

Best ResponseYou've already chosen the best response.02x/2=−2y+29/2 Let's solve for x. (x−5)(2)+(y+3)(2)=25 Step 1: Add 4 to both sides. 2x+2y−4+4=25+4 2x+2y=29 Step 2: Add 2y to both sides. 2x+2y+−2y=29+−2y 2x=−2y+29 Step 3: Divide both sides by 2. 2x/2=−2y+29/2 x=−y+292 SIMPLIFY: 29/2=14.5 14.5/2= 7.25 7.25/2= Answer: 12.5

Best ResponseYou've already chosen the best response.2The equation of a circle is, (x−h)^2+(y−k)^2=r^2 So if we look at the given equation of the problem, (x  5)2 + (y + 3)2 = 25 Which part of the given equation gives you a hint about the radius in reference to out model equation of the circle?
