Answer:
D. 
Step-by-step explanation:
Given

Required
Determine its equivalent
<em>From the list of given options, the correct answer is</em>

This is shown as follows;

Multiply both sides by 

Open Bracket


Subtract x from both sides


Multiply both sides by -1


Reorder

<em>Hence, the correct option is D</em>

Factor the left side:
x (19+ r)= -37 + w
x= (-37 + w) / (19 +r)
Answer:
x²+y²-4x-6y+12.75=0
Step-by-step explanation:
The equation is given by (x-h)²+(y-k)²=r²
center is (2,3), so h=2, k=3,r=0.5
equation is given by;
(x-2)²+(y-3)²=0.5²
Expand
x(x-2)-2(x-2)+y(y-3)-3(y-3)=0.5²
4-2x-2x+x²+9-3y-3y+y²=0.25
4-4x+x²+9-6y+y²=0.25
x²-4x+13+y²-6y=0.25
x²-4x+y²-6y+13=0.25
x²-4x+y²-6y+12.75=0
x²+y²-4x-6y+12.75=0
