Step-by-step explanation:
The given function is
The graph of this function is a parabola that opens downwards
The line intersects this parabola, when
The teammate can spike the ball after 0.25 seconds or 0.5 seconds.
The two solutions are reasonable. When the volleyball is accelerating into the air, it passes a height of 8 after 0.25 seconds.
When the ball is dropping after it attains maximum height, it attains another height of 8 after 0.5 seconds again.
Answer:
Subtraction Property of Equality.
Step-by-step explanation:
To solve x + 8 = 9, you need to subtract 8 from both sides of the equation. So, you would be using the Subtraction Property of Equality.
Hope this helps!
