Answer:
c) the marble is either red or green?
Step-by-step explanation:
Y= -6
move 8 to the right and change it’s sign
so it becomes -4y= 16 + 8
( add )
-4y= 24
(Divide it by -4)
-4y/24
Y= -6
2×2 in a fraction is two over one times two over one
Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :

The discriminant of this equation is : 
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
