Which of these equations represents a proportional relationship? a)y = 4x + 8 b) x = 2y - 5 c) 2x + 3y = 15 d) y = 4x

D y= 4x

Step-by-step explanation:

Proportional relationships must go through Zero, so we cannot be adding a constant in our equation

A, B , C add a constant, so they are not proportional

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
