What is the discriminant of the quadratic equation 0=2x^2 + 3x -5? 0-37 -31 0 43 049​

Discriminant = b²-4ac

from 2x²+3x-5=0

a = 2 b = 3 and c = -5

Discriminant = 3² - 4(2)(-5)

= 9+40

= 49

Discriminant = 49

Ans = 49

step-by-step explanation:

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
