The solution of a+b>−4 is a>−9. What is the value of 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.

look a the sides they are perpendicular

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
