The cost, c(x), for a taxi ride is given by c(x)=2x+4.00,where x is the number of minutes. what does the slope mean for this situation?

. The rate of change of the cost of the taxi ride is $2.00 per minute.

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.
