Answer:
Step-by-step explanation:
2x^2-2x-12
This has solutions of x=3 and x= -2
2 and 1/4 miles is how far Mary walks around the track. This is because she walks for 15 minutes before Jerry gets there, which is 0.75 miles at 3mph. Then Jerry goes for 2 miles, which is half an hour. Half an hour is double 15 minutes, so it's double 0.75 miles. So 0.75 plus 1.5 = 2.25 Mark me brainliest :3
The acceleration is defined as the ratio between the change in velocity and the time elapsed to perform such a change.
These "changes" are indicated with the capital greek letter delta, 
, and when you write 
you mean the difference between the finial and the inital values of the variable x:
So, the acceleration is defined as
In this case, the initial velocity is 35, the final velocity is 65. Assuming we start the clock at the beginning of the observation, the inital time is 0 and the final time is 5. So, we have
m/s^2
Answer:
-2150000
Step-by-step explanation:
I hope this right cause my head hurt doing that
Answer:
answer is
{X^2 + 4, X<2
{X + 4, X>2
Step-by-step explanation:
Because both solution set graph is at the begining hole at the value of X = 2 this means both sets doesn't contain 2.
