8-4/5f=-14-2f
Multiply both sides by 5
40-4f=-70-10f
Move variable to left and change signs
-4f+10f=-70-40
Combine like terms
6x=-70-40
6f=-110
Divide both sides by 6
F=-55/3

stiv31 [10]
Answer:
Fraction of fence = 2/3 which is approximately 0.67

Explanation:
We know that he finishes 1/3 of the fence in 1/2 an hour. To know the fraction he can finish in one hour, we will simply use cross multiplication as follows:
1/3 of the fence ...................> 1/2 an hour
?? of the fence ....................> 1 hour
Fraction of the fence = (1/3 * 1) / (1/2)
Fraction of fence = 2/3 which is approximately 0.67

Hope this helps :)

write an equation for a circle with a diameter that has endpoints at (-4, -7) and (-2, -5). round to the nearest tenth if necess
andrezito [222]

Answer:

The answer to your question is          (x + 3)² + (y + 6)² = 2

Step-by-step explanation:

Endpoints (-4, -7) and (-2, -5)

Process

1.- Find the length of the radius

   d = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }

   d = \sqrt{(-2 + 4)^{2}+ (-5 + 7)^{2}  }

   d = \sqrt{2^{2} + 2^{2} }

   d = \sqrt{4 + 4}

   d = \sqrt{8}

   Radius = \frac{\sqrt{8} }{2} = \sqrt{2}

2.- Find the center

Xm = \frac{-4 - 2}{2} = \frac{-6}{2} = -3

Ym = \frac{-7 - 5}{2} = \frac{-12}{2} = -6

Center = (-3, -6)

3.- Write the equation

                                   (x - h)² + (y - k)² = r²

                                   (x + 3)² + (y + 6)² = (\sqrt{2})²

                                   (x + 3)² + (y + 6)² = 2

Determine the total number of roots of each polynomial function f(x)=3x^6+2x^5+x4-2x^3
Alisiya [41]

Answer:

6 roots

Step-by-step explanation:

f(x)=3x^6+2x^5+x4-2x^3

The number of roots is determined by the degree of the polynomial.  They may be real or complex.

Since this is a 6th degree polynomial, it will have 6 roots

f(x)=3x^6+2x^5+x4-2x^3
