If the endpoints of the diameter of a circle are (6, 3) and (2, 1), what is the standard form equation of the circle? a) (x + 4)2 + (y + 2)2 = 5 b) (x − 4)2 + (y − 2)2 = 5 c) (x + 4)2 + (y + 2)2 = 5 d) (x − 4)2 + (y − 2)2 = 5

Astudent found the solution below for the given inequality. |x-9|< -4 x-9> 4 and x-9< -4 x> 13 and x< 5 which of the following explains whether the student is correct? -the student is completely correct because the student correctly wrote and solved the compound inequality. -the student is partially correct because only one part of the compound inequality is written correctly. -the student is partially correct because the student should have written the statements using “or” instead of “and.” -the student is completely incorrect because there is no solution to this inequality.
