Answer:
The Nikes cost $125.
The Adidas cost $100
Step-by-step explanation:
Let :
- a = # of adidas shoes
- n = # of nike shoes
Solve the bottom equation for a:
- a + 2n = 350
- a = 350 - 2n
Now substitute this for a in the top equation:
- 3a + 4n = 800
- 3(350 - 2n) + 4n = 800
- 1050 - 6n + 4n = 800
- 1050 - 2n = 800
- -2n = -250
- n = 125
The Nikes costs $125.
We can also solve for the Adidas:
Use the previous equation we made:
- a = 350 - 2n
- a = 350 - 2(125)
- a = 350 - 250
- a = 100
The Adidas costs $100

Answer:
Table 4th is showing the function that is decreasing only over the interval
Step-by-step explanation:
We have been given four tables below:
To determine the function that is decreasing only in the given interval
We will check the values after -1 in all four tables
The table in which values is only decreasing after -1 will be the table which shows a function is decreasing only.
In table 1 the value of x is increasing
In table 2 and 3 the value is increasing and then decreasing but we will consider only decreasing case
Therefore, Table 4th is correct.
