The answer is A, 8.94 seconds.
Since Gary ran 0.93 seconds faster than Brian, his time will have 0.93 seconds more than Brian's. To figure out Brian's time you have to subtract these 0.93 seconds from Gary's time.
9.87 - 0.93 = 8.94
I hope this helps!
Answer:
- Infinitely many solutions
Step-by-step explanation:
- 2x + x + 4 = 3x + 4
- 3x + 4 = 3x + 4
Both sides of the equation are exactly same.
It means regardless the value of x the equation is true.
The equation has infinitely many solutions.
Answer:
Average rate of change = 0.6
Step-by-step explanation:
Average rate of change of a function between x = a and x = b is given by,
Average rate of change = 
From the graph attached,
f(-5) = 0
f(0) = 3
Average rate of change of the graph between x = -5 and x = 0,
Average rate of change = 
= 
= 0.6
Therefore, average rate of change of the given function between x = -5 and x = 0 is 0.6.
