Given the pre-image circle with the equation: (x-4)² + y² = 5, what is the equation of the circle translated left 2 units and up 3 units?

• (x-2)² + (y-3)² = 5

• (x-2)² + (y+3)² = 5

• (x-6)² + (y-3)² = 5

• (x-6)² + (y+3)² = 5

A circle has the equation  x² + y² + 3 = 12x - 8y. Write the equation in standard form.

• (x - 6)² + (y + 4)² = 49
• (x + 4)² + (y - 6)² = 49
• (x + 6)² + (y - 4)² = 49

• (x - 4)² + (y + 6)² = 49
