Evaluate

More Steps

57 r - 14 = - 5

Rewrite the expression

57 r = 14 - 5

Simplify the expression

57 r = 9

Square both sides of the equation

(57 r)^{2} = 9^{2}

Evaluate

3249 r^{2} = 9^{2}

To covert the equation to rectangular coordinates using conversion formulas,substitute x^{2} + y^{2} for r^{2}

3249 (x^{2} + y^{2}) = 9^{2}

Evaluate the power

3249 (x^{2} + y^{2}) = 81

Divide both sides of the equation by 9

361 (x^{2} + y^{2}) = 9

Solution

361 x^{2} + 361 y^{2} = 9
