Which of the following represents the factorization of the binomial below?
81x2 – 25y2
A. (9x - 5y)(9x - 5y)
B. (9x - 5y)(9x + 5y)
C. (9x - y)(x + 5y)
D. (9x + 5y)(9x + 5y)

Answer:

y = 12/7

Step-by-step explanation:

Slope = (change in Y) / (change in x)

-1/7 = (y - 2) / (3 - 1)

-1/7 = (y - 2)/2

Cross multiply:  -1(2) = 7(y - 2)

                             -2 = 7y -14

                        -2 + 14 = 7y

                                12  = 7y

                               12/7 = y

Let's find y

[tex]\\ \sf\longmapsto m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \sf\longmapsto \dfrac{-1}{7}=\dfrac{y-2}{3-1}[/tex]

[tex]\\ \sf\longmapsto \dfrac{-1}{7}=\dfrac{y-2}{2}[/tex]

[tex]\\ \sf\longmapsto -2=7y-14[/tex]

[tex]\\ \sf\longmapsto 7y=12[/tex]

[tex]\\ \sf\longmapsto y=12/7[/tex]

It is observed that point (18, 206) does not lie on the line. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The equation is given below.

y = 12x

Where 'y' represents the number of gallons of water in the pool and 'x' represents the number of minutes the water runs.

The equation is drawn below.

From the chart, it is seen that point (18, 206) doesn't lie on the line. Then the right choice is D.

Answer:

92 miles

Step-by-step explanation:

The area of a square is Length x Width.  All sides of a square are equal in length so length = width.  This is the same as saying x = length and x = width so   X times X equals the area.  X times X is X².

This tells you that X² = 529 mi².   X would equal the square root of 529 which is 23.     23  x  23  = 529.

Each side of the square is 23 miles.  The perimeter is equal to side 1 plus side 2 plus side 3 plus side 4.  Again since it is a square all sides are equal.

This mean you can just take 4  x  23 miles.  The perimeter = 92 miles

Answer:

The perimeter of the region is 92 miles

Step-by-step explanation:

For a given Square

Area = 529 mi²

Now, To find area we use formula

A = (l)²

529 = l²

√529 = l

23 = l

l = 23 miles

Now, To find perimeter of square we use,

P = 4l

P = 4 (23)

P = 92 miles

Thus, The perimeter of the region is 92 miles

Answer:

x = 7 is not there in the domain of the function.

Step-by-step explanation:

The value of x = -3 would not be in the domain of the function

We have the following information available from the question is:

The function is :

[tex]f(x) =\frac{x-2}{x+3}[/tex]

Determine the values of x would not be in the domain of the function

Now, According to the question:

The function is :

[tex]f(x) =\frac{x-2}{x+3}[/tex]

Let the denominator equal to zero: x + 3 = 0

Rearrange unknown terms to the left side of the equation.

x + 3 = 0

x = -3

Hence, The value of x = -3 would not be in the domain of the function.

Answer:

  perpendicular: undefined

  parallel: zero

Step-by-step explanation:

The line y = -6 is a horizontal line. Between any two points on the line, the difference in y-values is zero, and the difference in x-values is non-zero. The slope of this horizontal line is the ratio of these differences:

  slope = 0/(non-zero) = 0

Any parallel line will have the same slope. The slope of a parallel line is 0.

__

A line perpendicular to a horizontal line is a vertical line. It will have the equation x = constant. Between any two points on the line, the difference in y-values is non-zero, and the difference in x-values is zero. The slope of this vertical line is the ratio of these differences:

  slope = (non-zero)/0 = undefined

The slope of the perpendicular line is undefined.

p = 7

Step-by-step explanation:

i think there's a proper equation to solve these kinds of problems but you can think about numbers times 6 (1x6 = 6, 2x6 = 12, 3x6 = 18,...)

The value of p will be 7.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

p is a whole number.

And, 6p is greater than 40 and less than 45.

Now,

Since, 6p is greater than 40 and less than 45.

Hence, We can formulate;

⇒ 40 < 6p < 45

Solve for p as;

⇒ 40 < 6p < 45

Divide by 6, we get;

⇒ 40/6 < 6p/6 < 45/6

⇒ 6.67 < p < 7.5

Since, p is a whole number.

Hence, The value of p = 7

Thus, The value of p will be 7.
