What types of solutions will a quadratic equation have when the discriminant b^2- 4ac in the quadratic formula is positive
two nonreal solutions
one real solution
two real solutions
no solutions

For this case we have that by definition, the discriminant of a quadratic equation, , is given by:

We have to:

: Two different real roots

: Two equal real roots

: Two different complex roots

Thus, the answer is option C.

Option C

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
