Answer:

[tex](x+3)(x-3)[/tex]

Step-by-step explanation:

This equation is called a "difference in perfect squares".

The resulting answer should be: [tex](x + y)(x-y)[/tex] where the y variable is the square root of the given number. In this instance, the integer 9

So knowing that the square root of 9 is 3 we can plug in 3 for both of the y spots which results in our answer.

If you wish to check this answer you can peform the "FOIL" method (first, outside, inside, last) in order to solve the equation which would result in:

[tex]x^{2}-9[/tex]

Answer:

C: Xint = 2, Yint. = -7

Step-by-step explanation:

Given the equation, 2x - 7y = -14:

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0.  To solve for the y-intercept, set x = 0:

2x - 7y = -14

2(0) - 7y = -14

0 - 7y = -14

-7y = -14

Divide both sides by -7 to solve for y:

-7y/-7 = -14/-7

y = 2

Therefore, the y-intercept = 2.

Next, the x-intercept is the point on the graph where it crosses the x-axis, and has coordinates, (a, 0). To find the x-intercept, set y = 0 and substitute into the given equation:

2x - 7y = -14

2x - 7(0) = -14

2x - 0 = -14

2x = -14

Divide both sides by 2 to solve for x:

2x/2 = -14/2

x = -7

x-intercept = -7.

Therefore, the correct answer is C: Xint = 2, Yint. = -7

x=20

Step-by-step explanation:

Answer:

x=20

Step-by-step explanation: Sorry the explination is long i got it of a website i use for my math tests.

Simplifying

3x + 3 = 6x + -57

Reorder the terms:

3 + 3x = 6x + -57

Reorder the terms:

3 + 3x = -57 + 6x

Solving

3 + 3x = -57 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

3 + 3x + -6x = -57 + 6x + -6x

Combine like terms: 3x + -6x = -3x

3 + -3x = -57 + 6x + -6x

Combine like terms: 6x + -6x = 0

3 + -3x = -57 + 0

3 + -3x = -57

Add '-3' to each side of the equation.

3 + -3 + -3x = -57 + -3

Combine like terms: 3 + -3 = 0

0 + -3x = -57 + -3

-3x = -57 + -3

Combine like terms: -57 + -3 = -60

-3x = -60

Divide each side by '-3'.

x = 20

Answer:

D.3.141141114

Step-by-step explanation:

3.141141114 is an irrational number because it has not teminating non repeating condition.

Work Shown:

Data set = {3, 6, 5, 5, 5, 7, 6, 4, 6, 7, 7, 3}

Sorted data set = {3, 3, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7}

We see that the numbers 5, 6, and 7 show up exactly three times. This is the most frequent compared to something like 4 that only shows up once. Therefore, the modes are 5, 6, 7.

Answer:

20 quarts = 20 x (1 quart ) = 20 x 1/4 gallon = 5 gallons

Step-by-step explanation:

Answer:

Step-by-step explanation:

First we are going to find the function which models the height of the

periscope lens at time t.

Let the 2 be height of the periscope.

The height of the periscope at the beginning is 24 inches. It ascends at 6

inches per second. The expression which describes how much it has raised,

at the moment, is 6t.

The function is sum of beginning height and how much it has raised, 2 = 24 + 6t.

To find maximum height of the periscope, we need to evaluate function

for + = 22.

2 = 24 + 6(22)

= 24 + 132

156

Substitute 22 for t.

Multiply.

Maximum height in inches is 156.

We know that 1 foot is 12 inches.

So the function that describes converting feet to inch is y :

= 12x. Where y

represents number of inches and a number of feet.

U = 12.2

156

12x

12

-n=

156

12

2 = 13

Substitute 156 for y.

Divide both sides by 12.

Maximum height in feet is 13.

The height function modeled by the periscope is an illustration of a linear function.

The given parameters are:

[tex]\mathbf{Start = 24\ inches}[/tex]

[tex]\mathbf{Rate = 6\ inches/second}[/tex]

The function model of the height is calculated using:

[tex]\mathbf{h(t) = Start + Rate \times t}[/tex]

Where: t represents the time in seconds

So, we have:

[tex]\mathbf{h(t) = 24+ 6\times t}[/tex]

This gives

[tex]\mathbf{h(t) = 24+ 6t}[/tex]

After 22 seconds, the height of the periscope would be

[tex]\mathbf{h(22) = 24+ 6 \times 22}[/tex]

Multiply

[tex]\mathbf{h(22) = 24+ 132}[/tex]

Add

[tex]\mathbf{h(22) = 156}[/tex]

Hence, the maximum height is 156 inches
