Answer:

(x-10)(x-2)

Formula:

a^{2} - b^{2} = (a-b)(a+b)  

Explanation:  

(x-6)^2-4^2

Then we can simplify to, (x-6-4)(x-6+4)

Which comes to your answer,  (x-10)(x-2)

Answer:

Step-by-step explanation:

x² − 12x − 20 = 0

a = 1;  b = (-12);  c = (-20)

b²-4ac = (-12)² - 4 * 1 * (-20) = 144 + 80 = 224

√b²-4ac = √ 224 = √ 2*2*2*2*2*7 = 2*2*√(2*7) = 4√14

delta = -b ± √b²-4ac / 2a

         = -(-12) ± 4√14

                    2 * 1

          = (12 ± 4√14)/2

           = 2 ( 6 ± 2√14) / 2

           =  6 ± 2√14

x =   6 + 2√14;  x =  6 - 2√14

Answer:

(2, 9)

Step-by-step explanation:

We've been given the exponential function;

f(x) = 25(3/5)^x

We need to determine the value of f(x) when x = 2, that is;

f(2) = 25(3/5)^2

Using a calculator we obtain

f(2) = 9

Thus the next point she plots on the graph will be (2, 9)

Step-by-step explanation:

There can be two situations

1. When maggie is older

The equation becomes x = y + 3

It can also be expressed as y = x - 3

2. When maggie is younger

The equation becomes y = x + 3

Table of possible values

1. x    y          2. x    y

  5   2              2   5

  6   3              3   6

Answer:

The required equation is [tex]|y-x|=3[/tex]. If maggies is elder, then [tex]y_1=x-3[/tex] and if maggies is younger, then [tex]y_2=x+3[/tex].

Step-by-step explanation:

Let the x represents maggies age and y represents terrance age, make a table of possible values for x and y.

It is given that the difference between maggies age and terrance age is 3.

It means

[tex]|y-x|=3[/tex]

On simplification, we get

[tex]y-x=\pm 3[/tex]

[tex]y=x\pm 3[/tex]

Case 1: If maggies is elder.

[tex]y_1=x-3[/tex]

Case 2: If maggies is younger.

[tex]y_2=x+3[/tex]

The table of values is

x      y₁      y₂

-3    -6      0

0    -3      3

3     0      6

The graph of both functions are shown below.

Answer:

2n² = 12 + n

2n² - n - 12 = 0

[tex]n = \frac{1 ± \sqrt{ {( - 1)}^{2} - 4(2)( - 12)} }{2(2)} [/tex]

[tex]n = \frac{1 ± \sqrt{97} }{4} [/tex]

Answer:

Slope= 7/5

Step-by-step explanation:

The slope of a line is determined as a ratio of the change in y to the change in x.

Slope=Δy/Δx

Δy=y₂-y₁

Δx=x₂-x₁

Therefore we can use the the x and y coordinates from the points given, (-3,0) and (2,7) to calculate the slope.

m= (7-0)/(2-⁻3)

Slope= 7/5

When a negative number is subtracted from a number it the operation sign changes to addition.

Answer: Last option

[tex]slope=\frac{7}{5}[/tex]

Step-by-step explanation:

The equation to find the slope m of a line is:

[tex]m=\frac{y_2-y_2}{x_2-x_1}[/tex]

Where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are two points through which the line passes

In this case the points are: (-3, 0) and (2, 7)

Therefore the slope is:

[tex]m=\frac{7-0}{2-(-3)}[/tex]

[tex]m=\frac{7}{2+3}[/tex]

[tex]m=\frac{7}{5}[/tex]

The answer is the last option

Time= distance/speed (T = d/s)

Rate or speed are similar since they both represent some distance per unit time such miles per hour and kilometers per hour. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

distance = rate x time To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

This is because, speed of the object refers distance travelled divided by time or it expressed as, Furthermore, 1 could also explain the relationship of the time with other two variables using this formula. Speed could be of 2 types, relative or average.

from the formula,

Distance = time * speed

Speed = distance/time

Time= distance/speed (T = d/s)

So basically distance divided both of them when it find speed distance divide time when fine time distance divide speed.

The correct option is B.

Step-by-step explanation:

Let x is the  air conditioning unit's actual capacity and y is the maximum variance in British thermal units (Btu).

It is given that an air conditioning unit promises to have a cooling capacity of 6,000 British thermal units (Btu).

It means the maximum variance is less than or equal to absolute difference of actual capacity and 6,000.

A sequence exists as a function whose domain is the set of natural numbers.

A sequence exists as a function whose domain is the set of natural numbers or a subset of the natural numbers. Usually use the symbol a to describe a sequence, where n is a natural number and a stands for the value of the function on n. Intuitively, a sequence exists just as an ordered list of (possibly infinitely many) numbers.

Answer:

Possible values of x are   50 < x < 110.

Step-by-step explanation:

Consider the perimeter of the field:

2x + 2(x + 30) < 500

2x + 2x + 60 < 500

4x < 440

x < 110.

Consider the area of the field:

x(x + 30 ) > 4000

x^2 + 30x - 4000 > 0

(x - 50)(x + 80) > 0

The critical values are x = -80 and 50.

As x is a width it must be positive so x > 50.

Step-by-step explanation:

Answer:

The value of f(-4) = -80

Step-by-step explanation:

It is given that,  f(x) = -5x²

To find the value f(-4)

Let  f(x) = -5x²

To find the value of f(-4), substitute -4 instead of x

f(-4) =  -5 * (-4)²

 = -5 * 16      [ since (-4)² = -4 * -4 = 16 ]

 = -80

Therefore the value of f(-4) = -80

Answer:

The best cluster would be Philadelphia which percentage of 27% is nearly close to 28% of the whole united states population percentage.

Step-by-step explanation:

The correct option for the city which would be considered as the best cluster is B. Miami,  16% of the population are MyBook users.

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

Now given that,

Amount of population that are MyBook users = 28%

Thus,

Amount of population that do not uses MyBook = 100% - 28% = 72%

Thus, Philaldephia and Denver cannot be percentage of the population who are MyBook users.

Thus, the correct option for the city which would be considered as the best cluster is B. Miami, 16% of the population are MyBook users.
