Answer:
2,5
Step-by-step explanation:
2,5 is just one of the many solutions to this problem. you can just take a random number for x, for example 2. your equation will look like this 3(2)-y=1. now you just solve for y. 3x2=6. 6-1=5. so y=5.
3 is to 5 as x is to 20
5 goes into 20 4 times so 3(4) gives you x
and x=12
The linear function that models the situation is given by:

------------------------
A linear function for the cost C of taking care of p puppies has the following format:

In which:
- C(0) is the fixed cost.
- a is the slope, which is the cost per puppy.
------------------------
- With 6 puppies, it costs $172. With 10 puppies, it costs $220. The slope is given by the <u>change in the output(cost) divided by the change in the input(number of puppies)</u>, thus:

Thus:

------------------------
The cost of $172 with 6 puppies means that when p = 6, C = 172, and we use this to find C(0).




Thus, the linear model is:

The area of the new square is 9k. For example if in the original square, each side was 2, then k=4. 2*3=6 so each side would be 6 long. 6*6 is 36 so the new square's area is 9 times the original.
