How many different ways can 6 flags be placed 3 to 3 to indicate the top three positions of athletes of different nationalities in a competition? a)12...
b)11...
c)10...
d)9...

In order not to guess, I will decrease the final character of the alternatives by 1 and put '' ... ''. So I'll know if your answer is right or not.

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.
