Answer:
It's at about 6.18
Step-by-step explanation:
The red dot is past 6 and there are three marks until 7, so each of those marks would count as .25. The red dot is about a little more than half of the way to the first mark which would stand for .25, so the red dot would be at about 6.18.

Answer:
discriminant = 0
The real root -2/3
Step-by-step explanation:
The formula for discriminant : b^2 - 4ac
12^2 (-4)×9×4 = 144 - 144 ➡ discriminant = 0 this means the roots is a repeated real number, which means there's only one solution
(3x + 2) × (3x + 2) = 0
3x+ 2 = 0
x = -2/3
