960 because 0.8(80%) • 1200 = 960
We want to find an equation for the given solutions and the multiplicity of each solution.
The equation is:

First, assume that we have a given equation and we know that we have solutions {x₁, x₂, ..., xₙ}, each one with multiplicity {m₁, ..., mₙ}.
The equation, of a polynomial that meets these requirements, is given by:

Where A is the leading coefficient and can be any real number.
Now that we know that, here we have the solutions:
- x = 2 with multiplicity 2
- x = -1 with multiplicity 2
We don't have information about the leading coefficient, so we assume it is equal to 1.
Then the equation is:

Answer:

Step-by-step explanation:
Given:
Interval, [0, 4]
Required:
Average range of change over [0, 4]
SOLUTION:
Find f(0) and f(4) from the graph:
(when x = 0, y = 0)
(when x = 4, y = 3)
Average rate of change = 
Where,


Plug in the values into the formula for average rate of change.


Average rate of change 
<span>5(b + 6) = 18
b + 6 = 3.6
b = -2.4
answer
</span><span>B. -2.4</span>
5y + 3 > -7 + 13
First add -7 + 13 = 6
5y + 3 > 6
Subtract 3 from both sides
5y + 3 -3 > 6 - 3
5y > 3
Divide both sides by 5
5y/5 > 3/5
y > 3/5
