A soccer tournament was designed with 25 teams where a fifth of the teams were eliminated after each round. Write a function, f(x), that models the number of teams still in the tournament after x rounds have been played.

0.5 meters per second

step-by-step explanation:

the average speed between 2 seconds and 8 seconds is 0.5 meters per second.

hope this ! mark brainliest!

its 4 because 2 times 2 is 4, if you double the number two you get four

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

i believe it's a.

i'm not sure on this one, most likely correct.
