Test: PSAT Math

1.

Circle A is given by the equation (x – 4)2 + (y + 3)2 = 29. Circle A is shifted up five units and left by six units. Then, its radius is doubled. What is the new equation for circle A?

(x + 2)2 + (y – 2)2 = 116

(x – 10)2 + (y + 8)2 = 116

(x – 2)2 + (y + 2)2 = 58

(x – 10)2 + (y + 8)2 = 58

(x + 2)2 + (y – 2)2 = 58
