If x²-5x +1 =0, what is the value of -<br><img src="https://tex.z-dn.net/?f=%28x%20%2B%20%20%5Cfrac%7B1%7D%7Bx%7D%20%29%20%20" i

<h3>Answer: 5</h3>

=================================================

Work Shown:

x^2 - 5x + 1 = 0

x^2 + 1 - 5x = 0

x^2 + 1 = 5x

(x^2 + 1)/x = 5 .... where x is nonzero

(x^2)/x + (1/x) = 5

x + (1/x) = 5

---------------

An alternative method involves solving the original equation using the quadratic formula. After you get the two roots x = p and x = q, you should be able to find that p + 1/p = 5 and also q + 1/q = 5 as well.

In this case,

p = (5 + sqrt(21))/2

q = (5 - sqrt(21))/2

Choose the correct conic section to fit the equation.

yanalaym [24]

Answer:

Option A) Circle.

Step-by-step explanation:

We are given the equation:

$(x - 3)^2 + (y - 12)^2 = 25$

A general equation of the circle is of the form:

$(x-h)^2 + (y-k)^2 = r^2$

where (h,k) is the center of the circle and r is the radius of circle.

Comparing the two equations, we get,

$(h,k) = (3,12)\\r = \sqrt{25} = 5$

Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.

What is the difference of the fractions? Use the number line and equivalent fractions to help find the answer.

Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

Subtracting a positive number moves you to the left on the number line. Subtracting a negative number moves you in the opposite direction, to the right.

Here, we start at -2 1/2 = -5/2, and we move 1 3/4 = 7/4 to the right from there. Each mark on this number line is 1/4 unit, so we move 7 marks. The results is ...

-2 1/2 -(-1 3/4) = -5/2 +7/4

= -10/4 +7/4 = -3/4
