Answer:
average speed = 8y/s
Step-by-step explanation:
- What is the player's average speed over this distance ?
Formula
s = d/t
d = 40 yards
t = 5 seconds
s = 40y/5s
= 8y/s
In the 
plane, we have 
everywhere. So in the equation of the sphere, we have
which is a circle centered at (2, -10, 0) of radius 4.
In the 
plane, we have 
, which gives
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the 
plane, 
, so
which is a circle centered at (0, -10, 3) of radius 
.
Isolate the variable by dividing each side by factors that don't contain the variable.

I would say A but I’m not 100% sure.
Answer:
- 12x² + 9x + 9
Step-by-step explanation:
(- 10x² + 2) + (- 2x² + 9x + 7 ) ← remove parenthesis
= - 10x² + 2 - 2x² + 9x + 7 ← collect like terms
= - 12x² + 9x + 9
