Aleks04 [339]

Answer:

y>2x-5

Step-by-step explanation:

-2y+4x<10

-2y<10-4x

divide by -2 to isolate the y

y>-5+2x

Since we are dividing by a negative the sign flips.

Our final answer is y>2x-5

Compute the greatest root of x^4-x^3-19x^2+4x+60=0. Express your answer in simplified radical form.
erik [133]

Answer:

your answer can be either

Step-by-step explanation:

x = 5

x = 3

 x=  0.0000 - 2.0000 i  

 x=  0.0000 + 2.0000 i  

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((((x4)-(8•(x3)))+19x2)-32x)+60  = 0  

Step  2  :

Equation at the end of step  2  :

 ((((x4) -  23x3) +  19x2) -  32x) +  60  = 0  

Step  3  :

Polynomial Roots Calculator :

3.1    Find roots (zeroes) of :       F(x) = x4-8x3+19x2-32x+60

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  1  and the Trailing Constant is  60.  

The factor(s) are:  

of the Leading Coefficient :  1

of the Trailing Constant :  1 ,2 ,3 ,4 ,5 ,6 ,10 ,12 ,15 ,20 , etc
