Find the difference quotient and simplify your answer. f(x) = 4x − x2, f(4 + h) − f(4) h , h ≠ 0
Anon25 [30]

The difference quotient and simplification will be    = [4 -h-2x]

The given equation is as follows:   f(x)= 4x - x²

For finding the quotient and further simplification we must follow the following steps:

[f(x + h) - f(x)] / h = [4(x + h) - (x + h)² - 4x + x²]/ h

<h3>What is simplification of algebraic operations?</h3>

Getting the functions in their lowest terms is known as simplification.

Brackets will get open and solved further;

[f(x + h) - f(x)] / h = [4(x + h) - (x + h)² - 4x + x²]/ h

[f(x + h) - f(x)] / h = [4h - h² - 2x]/ h  

Finally dividing the whole equation with h;

                                = [4 - h - 2x]

Use the image above to write a conjecture about regular polygons and lines of symmetry
Tatiana [17]
To find conjecture about regular polygon, use the formula \frac{360}{n}

Where, n = number of sides of the regular polygone

1) Triangle
n =3
So, Conjecture of the triangle = \frac{360}{3} = 120

2) Square
n =4
So, Conjecture of the square = \frac{360}{4} = 90

3) Pentagone
n = 5
So, Conjecture of the pentagon = \frac{360}{5} = 72

4) Hexagone
n = 6
So, Conjecture of the pentagon = \frac{360}{6} = 60.

How to solve 3+5 (c+3)=-17
BlackZzzverrR [31]
3 + 5(c + 3) = -17

First, subtract 3 from both sides. / Your problem should look like: 5(c + 3) = -17 - 3
Second, simplify -17 - 3 to get -20. / Your problem should look like: 5(c + 3) = -20
Third, divide both sides by 5. / Your problem should look like: c + 3 =  -\frac{20}{5}
Fourth, simplify \frac{20}{5} to 4. / Your problem should look like: c + 3 = -4
Fifth, subtract 3 from both sides. / Your problem should look like: c = -4 - 3
Sixth, simplify -4 - 3 to get -7. / Your problem should look like: c = -7

Answer: c = -7
