Question

Taking the equation .9^2=(x+ 2.68)^2+(y-4.68)^2 and making it equal to Y

Answer 1

The goal is the solve for y.

 

Subtract (x + 2.68)² to both sides of the equation.

 

0.9² - (x + 2.68)² = (y - 4.68)²

 

 

Then square-root both sides of the equation.

 

±√(0.9² - (x + 2.68)²) = y - 4.68

 

 

Then add 4.68 to both sides of the equation.

 

4.68 ± √(0.9² - (x + 2.68)²) = y
