Step-by-step explanation:
first fish tank: 95-4x
second fish tank: 40+5x
1. Define variable
The variable x represents the number of days.
2. Write the inequality
<em>95-4x=40+5x</em>
<em />
3. You probably don't need the answer but I am just going to solve.
The first fish tank will have less water than the second fish tank after 7 days.
<em>95-4x=40+5x </em>
<em>95-4(7)=40+5(7)</em>
<em>95-28=40+35</em>
<em>67=75</em>
<em>Since the first equation (95-4x) represents the first fish tank, and the second equation (40+5x) represents the second fish tank, the solution shows how the amount of water in the first fish tank is less than the amount of water un the second fish tank after 7 days.</em>
Answer: Since the y intercept is (0, 4), b = 4 and the slope, m, is given as 2/3.

Answer:
it will not change
Step-by-step explanation:
the outlier is 3
the mode is the most occuring value in the list which is 16 before and after the 3 is removed
Answer:
( 1 + x) ( 7 - x)
Step-by-step explanation:
Here's what I did
16 - ( x - 3)^2....expand this
16 - (x² + 6x + 9).....after exanding
16 - 9 + 6x - x²......like terms together
7 + 6x - x² ......rearrange
-x² + 6x + 7......look for the product, sum and factors
( 1 + x) ( 7 - x)
Answer:
C no, because one x value corresponds to two different y values
Step-by-step explanation:
The x value of 3 goes to two different y values
This means this cannot be a function
This is not a one to one correspondence
