Answer:

x=−8

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    6*(x-1)-(9*(x+2))=0

(6 • (x - 1)) -  9 • (x + 2)  = 0

6 • (x - 1) -  9 • (x + 2)  = 0

Pull out like factors :

-3x - 24  =   -3 • (x + 8)

-3 • (x + 8)  = 0

Solve :    -3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    x+8 = 0

Subtract  8  from both sides of the equation :

  x = -8

6(x-1) = 9(x+2)

Use distributive property on both sides:

6x-6 = 9x + 18

Subtract 6x from both sides:

-6 = 3x + 18

Subtract 18 from both sides:

-24 = 3x

Divide both sides by 3:

X = -8

Determine the nature of the roots: 4x^2 + 32x + 64 = 0
DENIUS [597]

Answer:

b. a unique real solution

Step-by-step explanation:

A quadratic equation ax² + bx + c = 0 ,

Has two distinct real roots,

If discriminant, D=b^2 - 4ac > 1

Has two equal real roots,

If D = 0,

Has two imaginary roots or no real roots,

if D < 1,

Here. the given qudratic equation,

4x^2 + 32x + 64=0

By comparing,

a = 4, b = 32, c = 64,

\implies D = 32^2 - 4\times 4\times 64 = 1024 - 1024 = 0

Hence, the equation has two equal real roots or a unique real solution.

i.e. OPTION 'b' is correct.

What is diameter:

in geometry, a <u><em>diameter</em></u> of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.

What is radius:

In classical geometry, a <u><em>radius</em></u> of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.

Explanation:

The <u><em>diameter </em></u>is the line that goes across the center of the circle and double the <u><em>radius</em></u> which is half, therefore <u><em>KR</em></u> is the <u><em>correct answer.</em></u>

Answer:

<u><em>KR, D, or the last option.</em></u>

Statement answer:

<u><em>Segment KR is the Diameter of Q.</em></u>
