Step-by-step explanation:
We have the two functions:

And we want to find:

This is equivalent to:

Therefore, we will have:

By substitution:

Answer:
1. The y-intercept 8 means you start off with $8. The slope 1/4 means how much money you have to pay for the amount of tickets purchased for carnival games.
2. The y-intercept 2 means the number of chapters you started reading and the slope 5/4 means the number of chapters you read per day.
3. The y-intercept 3 means the inital (start) cost of a muffin delivery and the slope 2 means the cost of each muffin delivery for the number of muffins you ordered.
Number 3 on the slope part might be the other way around if I'm wrong :)
Answer:
The answer is letter c.
Step-by-step explanation:
In order to know the answer, it is best to check what is given in the scenario above.
45 minutes = the time it takes for Betty and Dyan to pick 8 quarts of strawberries.
45x minutes= this refers to the time it takes for Dyan to pick 8 quarts of strawberries
In the rational expression, 45x-10, we've already known that 45x refers to minutes or the time it takes for Dyan to pick 8 quarts of strawberries, thus 10 here refers to minutes or time as well.
The mathematical operation used is<u> "subtraction,"</u> so this means that Betty takes a shorter time than Dyan when it comes to picking strawberries in the situation above.
Thus, the denominator represents the time it takes Betty to pick 8 quarts of strawberries if she takes 10 fewer minutes than Dyan.
Y=8x-7 Is the answer. I hope this helps you <3!!
