what are the values of x in equation x^2-6+9=25

Answer:

fudjdhajs gf djdjsiwjsj

By definition of f(x),

f(k) = 1 - 2k + k = 1 - k

Then

f(f(k)) = f(1 - k) = 1 - 2 (1 - k) + k = 3k - 1 = 13

Solve for k :

3k - 1 = 13

3k = 14

k = 14/3

Find f(-1) :

f(-1) = 1 - 2 (-1) + 14/3 = 1 + 2 + 14/3 = 23/3

The difference of given expressions is 6x+14.

To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.

Given that, 8(x+3)-2(x+5)

8x+24-2x-10 (By distributive property of multiplication)

(8x-2x)+(24-10) (Grouping like terms)

6x+14

Therefore, the difference of given expressions is 6x+14.

Answer:

Step-by-step explanation:

In general, given the function, f(x), its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.

Answer:

Use the rational root theorem to list all possible rational zeroes of the polynomial P(x) P ( x) .

Evaluate the polynomial at the numbers from the first step until we find a zero. ...

Repeat the process using Q(x) Q ( x) this time instead of P(x) P ( x) . This repeating will continue until we reach a second degree polynomial.

Answer: y=-x-1

Step-by-step explanation:

To find the answer, 5 and -6 have to be substituted in the place of x in the equation y = -x + b(The slope has to be the same because the line is parallel). -6 = -5 + b, b = -1. This means that the equation is y = -x - 1.

Answer:

Jack = 30

Lacy = 15

Step-by-step explanation:

Let the age of Lacy be " x ".

Jack Is 2 times as old as lacy,

Age of Jack = 2 * Age of Lacy

Therefore,

Age of Jack = 2x.

8 years from now,

the age of Jack = 2x + 8

the age of Lacy = x + 8

8 years from now the sum of their ages will be 61,

2x + 8 + x + 8 = 61

2x + x + 8 + 8 = 61

3x + 16 = 61

3x = 61 - 16

3x = 45

x = 45 / 3

x = 15

The age of Jack

= 2x

= 2 * 15

= 30 years old.

The age of Lacy

= x

= 15 years old.

Hence,

Now,

the age of Jack is 30 years old.

the age of Lacy is 15 years old.

Answer:

  x = -8 or 2

Step-by-step explanation:

Compare your equation to the standard form equation.

  -x^2 -6x +16 = 0 . . . . . . your equation

  ax^2 +bx +c = 0 . . . . . . standard form equation

Identify the values of 'a', 'b', and 'c'.

  a = -1

  b = -6

  c = 16

Fill in these values in the quadratic formula and do the arithmetic.

  [tex]x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\dfrac{-(-6)\pm\sqrt{(-6)^2-4(-1)(16)}}{2(-1)}=\dfrac{6\pm\sqrt{100}}{-2}\\\\x=-3\pm5=\{-8,2\}[/tex]

The solutions are x = -8 and x = 2.

If two were in the ones place, which would look like this: 2, then you would have two of an object. So two dogs, cats, ect.

If two were in the tenths place, which would look like this: .2, then you have two thenths of an object. Not one complete object, just that amount of it.

Answer:

[tex]\bf\mathsf{X-intercept=(\frac{25}{3},\:0)}[/tex]

Y-intercept = (0, -5)

Step-by-step explanation:

Given the linear equation in standard form,  3x - 5y = 25, for which we must determine its x- and y-intercepts.

It is essential to understand what the intercepts mean relative to the given equation and its location on the graph.

The x-intercept is the point where the graph crosses the x-axis. Hence, its coordinates are often represented by (a, 0). Thus, the x-intercept provide the value of x when the value of the y-coordinate is 0.

Now, we can solve the x-intercept by setting y = 0:

3x - 5y = 25

3x - 5(0) = 25

3x - 0 = 25

3x = 25

Divide both sides by 3 to solve for x:

[tex]\large\mathsf{\frac{3x}{3}\:=\:\frac{25}{3}}[/tex]

[tex]\bf\mathsf{x=\:\frac{25}{3}}[/tex]

Therefore, [tex]\bf\mathsf{X-intercept=(\frac{25}{3},\:0)}[/tex] .

The y-intercept is the point where the graph crosses the y-axis. Hence, its coordinates are often represented by (0, b ). Thus, the y-intercept provide the value of y when the value of the x-coordinate is 0.

Now, we can solve the y-intercept by setting x = 0:

3x - 5y = 25

3(0) - 5y = 25

0 - 5y = 25

-5y = 25

Divide both sides by -5 to solve for y:

[tex]\large\mathsf{\frac{-5y}{-5}\:=\:\frac{25}{-5}}[/tex]

y = -5

Therefore, the y-intercept is (0, -5).

(a) The domain of the function is (-∞; 0) U (0; +∞) and the range is (-∞; +∞).

(b) There are 2 x-intercepts: (-2, 0) and (2, 0). There is no y-intercept.

(c) This function does not have horizontal asymptotes.

(d) The vertical asymptote is x = 0.

(e) The oblique asymptote is y = -3x.

We want to find different elements of the function given in the graph.

The intercept is a point where the graph of a function intersects the axis. There are 2 x-intercepts: (-2, 0) and (2, 0). There is no y-intercept.

Horizontal asymptotes are horizontal lines that the graph of the function approaches as x tends to +∞ or −∞. This function does not have horizontal asymptotes.

Vertical asymptotes are invisible vertical lines that certain functions approach, yet do not cross, when the function is graphed. The vertical asymptote is x = 0.

An oblique asymptote is a slanted line that the function approaches as x approaches ∞ or -∞.

We have 2 points for this asymptote: (0, 0) and (2, -6). We can find its expression using the two-point form of a line.

y - y₁ = (y₂-y₁/x₂-x₁) (x - x₁)

y - 0 = (-6-0/2-0) (x - 0)

y = -3x

(a) The domain of the function is (-∞; 0) U (0; +∞) and the range is (-∞; +∞).

(b) There are 2 x-intercepts: (-2, 0) and (2, 0). There is no y-intercept.

(c) This function does not have horizontal asymptotes.

(d) The vertical asymptote is x = 0.

(e) The oblique asymptote is y = -3x.

Answer:

Step-by-step explanation:

Width = w

Length = w + 6

Area = 112 sq. cm

length * width = 112

(w +6 ) *w = 112

w²  +6w -112 = 0

Sum = 6

Product = -112

Factors = 14 , -8    {14 - 8 = 6 , (-8)*14 = -112}

w² +  14w - 8w -112 = 0

w(w + 14) - 8(w + 14)=0

(w +14)(w -8) = 0   {Ignore w + 18 as measurement won't be negative}

w - 8 = 0

w = 8 ft

Length = 8 + 6 = 14 ft
