Which represents the solution(s) of the system of equations, y = x2 – 4x – 21 and y = –5x – 22? determine the solution set algebraically.

(–1, –17)
(1, –27)
(–1, –17) and (1, –27)
no solutions

No solutions

Step-by-step explanation:

We have been given the system of equations

Substituting the values y from (2) in (1)

Let us find the discriminant of this quadratic equation

Since, D is negative. Hence, there will not be any real zeros.

It means we'll not get any real values for x.

Therefore, there is no solution for the given system of equations.
