Question 13 • 25-26 TX-Precalculus B

Which point is a solution of x2 + y2 > 49 and y ≤ –x2 – 4?

Answer
A
(–8, –1)
B
(–3, 1)
C
(1, –9)
D
(0, –6)

Explanation

For (1, −9), x² + y² = 1² + (−9)² = 82, which is greater than 49. Also, −9 ≤ −(1²) − 4 = −5, so the point satisfies both inequalities. The correct choice is C, (1, −9).
