Tom determines the system of equations below has two solutions, one of which is located at the vertex of the parabola.
Equation 1: (x – 3)2 = y – 4
Equation 2: y = -x + b
In order for this solution to be reasonable, which qualifications must be met?

b must equal 7 and a second solution to the system must be located at the point (2, 5).
b must equal 1 and a second solution to the system must be located at the point (4, 5).
b must equal 7 and a second solution to the system must be located at the point (1, 8).
b must equal 1 and a second solution to the system must be located at the point (3, 4).

Respuesta :

b must equal 7 and a second solution to the system must be located at the point (2, 5)
  when b = 7  -------> (x - 3)^2 = y - 4   ,  y = -x + 7  x=2,   y=5  x=3,   y=4

b must equal 7 and a second solution to the system must be located at the point (2, 5). I just did edjenuity, systems, mixed degree systems and got 100%
