7z/4+5x if z=8 and x=3 PLEASE HELP THIS IS DUE IN 20 MINS.

What is the value of the discriminant of the quadratic equation -2x = -8x + 8 and what does its value mean about thenumber of real number solutions the equation has?

1.based of the diagrams what is the the value of x? 2.how would you verify your answer for x

Which equation shows y= 3 4 x− 5 2 in standard form? a 4x−3y=10 b 3x−4y=10 c 3x−4y=−10 d 4x−3y=−10
