Considerando a circunferência C: (x – 1)² + (y + 3)² = 9, determine a sua posição em relação a reta s de equação 3x - 2y + 8 = 0.

3. find the radius of circle p.4. find y.

7. if the value of x varies directly with the value of y, and x = 3 when y = 21. what is the valu y, and x = 3 when y = 21. what is the value of x when y = 105?

Solve the equation for x.3(6x - 1) = 12 i've tried doing the math and i can't find out what i'm doing wrong
