Alinear function that represents the number of hot dogs purchased at a football game is compared to a different linear function that represents the time left in the game. describe the key features of the functions that are needed to determine if these lines intersect.

Key features: the functions can not be parallels, this means that their respective slopes can not be equal or multiple to the other

Step-by-step explanation:

Take for instance 2 linear functions, and

If they intersect in some point in the space, say that is

Then (x1,y1)=(x3,y3), (x2.y2)= (x3,y3)

So, we can compare the two functions and get the following result=

It tells us that if M=m, we get an error, meaning that the functions are in fact parallels and there is no way that they meet in some point.

Hope it helps

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

just keep asking questions until you have a better understanding.
