Answer:
Step-by-step explanation:
the given equation is in the form of quadratic formula i.e.ax^2+bx+c=0.
So ,here a=-1 ,b=-6 and c=-9
b^2=(-6)^2
=36
4ac=4*(-1)*(-9)
=4*9
=36
b^2-4ac=36-36
=0
number of solutions =1

Answer:
Not a solution
Step-by-step explanation:
y ≥ 2x + 5
=> Substituting x = 2 and y = -1 in Equation,
=> -1 ≥ 2(2) + 5
=> -1 ≥ 4 + 5
=> -1 ≥ 9 [Not possible]
Therefore, (2,-1) is not a solution of y ≥ 2x + 5
