Answer:
v₁ = 2.5; v₂ = 0.5.
Step-by-step explanation:
4v² + 8v + 5 = 10
4v² + 8v + 5 - 10 = 10 - 10
4v² + 8v - 5 = 0
D = 8² - 4 · 4 · (-5) = 64 + 80 = 144

Answer:
The figure is a straight line.
The figure lies in the first and the third quadrants.
Step-by-step explanation:
Take five ordered pairs as 
Here, the first and second coordinates are equal.
Now, plot these points and connect them.
From the graph, it can be observed that the figure is a straight line.
Also, the figure lies in the first and the third quadrants.
Neither or them have a bigger half. Hope it helps!
