Given a line segment ab and a collinear point m, which must be true? a) m is on line ab b) m is in between a and b c) m is on line segment ab d) m is the midpoint of a and b

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
