Can you pls help me solve this question with test values?
Thnks
Alternate line of reasoning:
x² + y² = r² is the equation of a circle that is centered at the origin and has a radius of r.
Thus:
x² + y² = 100 is the equation of a circle that is centered at the origin and has a radius of 10.
Since every point on the circle must be 10 units from the origin, every point on the circle must have an x-coordinate no more than 10 units from the origin and a y-coordinate no more than 10 units from the origin.
In the other words:
|x| ≤ 10 and |y| ≤ 10.
Look for an answer choice that EXCEEDS this threshold.
Answer choice C:
|x| > |y| + 10.
Since the least possible value of |y| is 0, this answer choice implies that |x| > 10 -- EXCEEDING the threshold discussed above.
The correct answer is
C.
