erastovalidia [21]

Answer:

The discriminant b2−4ac < 0, the equation has no real number solutions, it has complex solutions

Step-by-step explanation:

9x² - 4x + 1 = 0 ax² + bx + c = 0

The discriminant: b² - 4ac = (-4)² - 4*9*1 = 16 - 36 = -20

Answer:

x=4

ME=9

AM=18

AE=27

Because m in the midpoint ME is double AM

2(4x-7)=5x-2 4(4)-7 5(4)-2 18+9

8x-14=5x-2 16-7 20-2 =27

-5x -5x =9 =18
