−504r−10
−504r−10=−145
Rewrite the expression
−504r=10−145
Simplify the expression
−504r=−135
Square both sides of the equation
(−504r)2=(−135)2
Evaluate
5042r2=(−135)2
To covert the equation to rectangular coordinates using conversion formulas,substitute x2+y2 for r2
5042(x2+y2)=(−135)2
Evaluate the power
5042(x2+y2)=18225
Divide both sides of the equation by 81
562(x2+y2)=225
Solution
3136x2+3136y2=225
