The equation representing the minimum and maximum number of fishes which would fit into the tank is : 5 ≤ x ≤ 9
From the table given ;
- Method 2 will allow the maximum number of fish = 9
- Method 1 will allow the minimum number of fish = 5
To represent the maximum and minimum number of fish that will fit into the tank;
We could use an inequality expression to represent these range :
Let x represent the Number of fishes that would fit into the tank :
Therefore, the equation can be written thus :

Answer:
(x-5)*(x+5)
Step-by-step explanation:
= x^2 + 5x - 25 - 5x
= x^2 +5x - 5x -25
because +5x - 5x = 0 so
= x^2 + 0 - 25
= x^2 - 25
25 can be written as 5^2
= x^2 - 5^2
we know that a^2 - b^2 = (a-b) * (a+b)
so x^2 - 5^2
= (x-5) * (x+5)

The point-slope formula:
We have (-2, 1) and (1, 7).
Substitute:
Answer:
72%
Step-by-step explanation:
You are looking at graduate students. There are 2610 of them.
Of those graduates 1879 have financial aid.
So the probability of a graduate student having financial aid is 1879/2610.
Inserting this division into my calculator provides me with about 72%.
First, find the slope (m) = 
= 
= 
= 
Now plug in ONE of the points and the slope into the point-slope equation:
y - y₁ = m(x - x₁); where (x₁, y₁) is the chosen point.
y - 5 = (x - 1) (I used (1,5) as the chosen point)
3(y - 5) = x - 1
3y - 15 = x - 1
3y -14 = x
-14 = x - 3y → x - 3y = -14
Answer: x - 3y = -14
