Domain (value of x) is any real value except x=13 or x=−25

The domain is the value of x in the function.

Here the denominator must not be zero.

The domain of a function is the set of inputs accepted by the function.

6x^2+13x−5≠0

or 6x^2+15x−2x−5≠0

or   3x(2x+5)−1(2x+5)≠0

or  (3x−1)(2x+5)≠0

or   x≠13  and   x≠−52

∴Domain (value of x) is any real value except x=13 or x=−25.

Answer:

20,000 feet

Step-by-step explanation:

Based on the initial altitude and the rate that the plane is descending, the relevant equation is = 30,000 - 2,000x. The altitude after 5 minutes is 20,000 feet above sea level.

The plane begins at 30,000 feet above ground and is descending at 2,000 feet per minute. The relevant equation after x minutes is:

= Initial altitude - (Descent in feet per minute x Number of minutes)

Plugging in the values gives:

= 30,000 - (2,000 × x)

= 30,000 - 2,000x

Answer:

x = 0 , -2 , 1 +i√3  ; 1 - i√3

Step-by-step explanation:

2x⁴ + 16x = 0

2x(x³ + 8) = 0

2x(x³ + 2³)  = 0

2x (x + 2)(x² -2x + 2²) = 0    {a³ + b³ = (a + b)*(a² -ab +b²}

2x = 0  

x = 0

x + 2 = 0

x = -2

x² - 2x + 4 = 0

a = 1 ; b = -2 and c = 4

D = b² - 4ac = (-2)² - 4*1*4= 4 - 16 = -12

[tex]\sqrt{D} = \sqrt{-12}=\sqrt{2*2*3i^{2}}=2i\sqrt{3}[/tex]

root = (-b ± √D)/2a

= (-(-2) ± 2i√3)/2*1

= (2 ± 2i√2)/2

[tex]= \dfrac{2(1 + i\sqrt{3})}{2} \ ; \dfrac{2(1+i\sqrt{3})}{2}\\\\\\= 1 + i\sqrt{3} \ ; \ 1 - i\sqrt{3}[/tex]

x / 5 = 20

Cross multiply,

x = 20 * 5

x = 100

Answer:

X = 100

Step-by-step explanation:

x/5 = 20

You do the same thing on the top as the bottom to cancel out and leave x by itself

5x/5 =20

whatever you do for one side you do for the other side

5x/5 = 20*5

the 5 cancel out leaving x by itself

so x = then 20 times 5 = 100

so x =100
