Answer:No, every whole number is not a solution of x > 0 because the whole numbers include 0. The solution set of x > 0 does not include 0. So, 0, which is a whole number, is not a solution of x > 0.

Step-by-step explanation:

No, Is it not true that every whole number is a solution of x > 0.

A relation by which we can compare two or more mathematical expression is called an inequality.

We have to given that;

To check, Is it true that every whole number is a solution of x > 0.

Now, We know that;

Every whole number is a solution of x ≥ 0.

That is, Zero is include in the whole numbers.

Therefore, Is it not true that every whole number is a solution of x > 0.

Answer:

B - A = 2

Step-by-step explanation:

Recall that parallel lines have the same slope.  Thus, line Ax + By = 3, parallel to x + 3y = -5, has the form x + 3y = C.  This latter line passes through the point (-7, 2), and so             -7 + 3(2) = C must be true.  Then -7 + 6 = C, and C = -1.  

In both equations A = 1 and B = 3.  Thus, B - A = 3 - 1, or B - A = 2

Answer:

A = 225 pi cm^2

Using 3.14 for pi

A =706.5 cm^2

Using the pi button for pi

A =706.8583471 cm^2

Step-by-step explanation:

The area of a circle is

A = pi r^2

A = pi (15)^2

A = 225 pi cm^2

Using 3.14 for pi

A =706.5 cm^2

Using the pi button for pi

A =706.8583471 cm^2

Answer:

225π cm^2, 706.5 cm^2, 706.858... cm^2

Step-by-step explanation:

The area of a circle can be found using the following equation:

[tex]a=\pi r^2[/tex]

We know the radius is 15 cm, so we can substitute 15 cm in for r.

[tex]a=\pi (15cm)^2[/tex]

1. In terms of pi

To find the area in terms of pi, evaluate everything possible without multiplying by pi.

Evaluate the exponent.

[tex]a=\pi (15cm)^2[/tex]

15cm^2= 15 cm * 15 cm = 225 cm^2

[tex]a=\pi * 225 cm^2[/tex]

This can be rewritten as:

[tex]a=225\pi cm^2[/tex]

2. Using 3.14 for pi

Substitute 3.14 in for pi.

[tex]a=\pi (15cm)^2[/tex]

[tex]a=3.14*(15cm)^2[/tex]

[tex]a=3.14*225 cm^2[/tex]

Multiply

[tex]a=706.5 cm^2[/tex]

3. Using 3.14159265.... as pi

[tex]a=\pi (15cm)^2[/tex]

[tex]a=\pi *225 cm^2[/tex]

Multiply, using the pi button on a calculator

[tex]a=706.858346 cm^2[/tex]

Answer: 2 <= X <= 5

Step-by-step explanation:

Answer: 2 <= X <= 5

Step-by-step explanation:

Given that a factory can work its employees no more than 5 days a week, that is, less than or equal to 5 days.

And no less than 2 days per week. That is, greater than or equal to 2 days.

Let X be the number of days employee can work. Then, according to the first statement, X <= 5 and according to the second statement, X >= 2

An inequality to represent the range of days an employee can work will be

2 <= X <= 5

Therefore, an employee can work for 2 days, 3 days, 4 days and 5 days

Answer:

x = ± 2[tex]\sqrt{6}[/tex]

Step-by-step explanation:

x = ± [tex]\sqrt{24}[/tex] = ± [tex]\sqrt{4(6)}[/tex] = ± [tex]\sqrt{4}[/tex] × [tex]\sqrt{6}[/tex] = ± 2[tex]\sqrt{6}[/tex]

Answer:

Table 2.

Step-by-step explanation:

Input x as 0, the output y should be 4.

y = -2(0) + 4

y = 0 + 4

y = 4

Input x as 1, the output y should be 2.

y = -2(1) + 4

y = -2 + 4

y = 2

Input x as 2, the output y should be 0.

y = -2(2) + 4

y = -4 + 4

y = 0

Answer:

15/3 = v/7 can be a true proportion.

Step-by-step explanation:

v is a variable, which means that technically any number can be put inside.

In this case, however, when you are solving for v, the numerator must be proportional to the denominator.

In the case of the question, the questioner multiplied ~2.33 to the denominator. Do the same to the numerator:

15 x 2.33 = ~34.95

If the variable v is ~34.95, then it is a true proportion.

Answer: 3

Step-by-step explanation:

Pretend A is just three, B is just 4, and C is just 5.

Answer: +3

Explanation: Start by plugging in the appropriate values for a, b, and c.

You might also want to change the -4b

to plus a negative 4b to avoid confusion.

Also, use parenthses when substituting numbers in for variables.

So we have 3(3) + -4(4) + 2(5).

Once you have plugged in your numbers, first multiply,

and then add from left to right.

So we have (9) + (-16) + (10).

Now add to get (-7) + (10) which is +3.

Required

Rewrite in simplest radical form

Using laws of indices:

[tex]a^m/a^n = a^{m-n}[/tex]

This implies that

[tex]x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{4}{6} }[/tex]

Simplify exponent to lowest fraction

[tex]x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{2}{3} }[/tex]

Using laws of indices:

[tex]a^{\frac{m}{n}} = \sqrt[n]{a^m}[/tex]

This implies that

[tex]x^{\frac{5}{6}}/x^{\frac{1}{6}} = \sqrt[3]{x^2}[/tex]

Answer:

Step-by-step explanation:

Using the graph we can notice something

let's take the abscissa  -2 and -4

so we can say that :

f(-4)=g(-2)

wait we khow that g(x)=f(k*x)

so x= -2 then let's replace it in the expression : f(k*x)

we get f(-4)=g(-2)=f[k*(-2)]

let's solve the equation: -2k = -4

                                               k = -4/-2

                                                k=2

so finally we get k=2

let's check :

from the graph we get :

we have (-1)*2 = -2

so it is true

The second denominator is actually made of two factors.

x^2 - 1 =(x + 1)(x - 1)

So the least common denominator is

x + 1

x - 1

You do not count the x - 1 twice.

Answer:

[tex]Probability = \frac{6}{29}[/tex]

Step-by-step explanation:

Given

------------------------------Has a brother | Does not have a brother

Has a sister --------------------------- 6 ----------------- 8

Does not have a sister  -----------2 ------------------ 13

Required

Probability of having a sister and a brother

First, the total number of students has to be calculated;

Total = 6 + 2+ 8 + 13

Total = 29

Number of students that have a sister and a brother is represented with data in row 1 and column 1 i.e. 6

At this point, the probability can then be calculated;

Probability = Number of students that have a sister and a brother divided by Total number of students

[tex]Probability = \frac{6}{29}[/tex]

Answer:

r = 105.

Step-by-step explanation:

In the quadratic formula, √r = [tex]{\sqrt{b^{2}-4ac }[/tex]

Where a = 1, b = -9, and c = -6. Therefore:

√r = √(-9)² - 4(1)(-6)

√r = √81 -4(-6)

√r = √81 + 24

√r = √105

Therefore, r = 105.

Answer:

Choice D 7/26

Step-by-step explanation:

So first let's count how many face cards there are. We have a Jack, a Queen, and a King in all of the 4 sets of cards. This knowledge tells us that we have 12 face cards out of the 52 cards.  Then, we have 2 red sixes in the game.  These come from the 6 of hearts and the 6 of diamonds.  This makes the new total of the cards we want to draw 12+2=14. Then we now have the fraction 14/52.  After simplifying we get the answer 7/26 is our probability (choice D)

Answer:

7/26

Step-by-step explanation:

52 cards

Jacks , queens, kings are face cards =

3 per suit *4 suits = 12 cards

2 red sixes = 2

P (red 6 or face cards ) = red 6 or face cards / total

                                    = (12+2) / 52

                                     = 14/52

                                     = 7/26

17-5=12

12÷3=4

Answer:

f(x) = √7x

g(x) = 1/x -8

To find the domain of f º g we must first find f o g(x)

To find f o g(x) wherever you see x in f(x) replace it by g(x)

That's

f o g = √7(1/x-8)

= √7 / √x - 8

To find the domain equate the denominator to zero

That's

√x - 8 = 0

Square both sides

(√x - 8)² = 0²

x - 8 = 0

x = 8

The domain of f o g is x E R except 8

Answer:

centre = (-5, -4)

radius = 7.42

Step-by-step explanation:

The general form for center-radius is

(x - h)² + (y - k)²= r²

Center = (h, k)

Radius = r

Rearrange the equation.

(x² + 10x) + (y² + 8y) - 14 = 0

Add 14 on both sides.

(x² + 10x) + (y² + 8y) = 14

(10/2)² = 25

(8/2)² = 16

Add 25 and 16 to both sides.

(x² + 10x + 25) + (y² + 8y + 16) = 14 + 25 + 16

Factor left side of the equation.

(x+5)² + (x+4)² = 55

(55) = (7.416198)²

(x+5)² + (x+4)² = 7.42²

The radius is 7.42.

The centre is at (-5, -4).

Answer:

The distance time graph shows the velocity with which Brianna traveled.

From t= 0 to t = 6:

For every 2 minutes, distance increase by one miles. She covers 3 miles in 6 minutes.

So the velocity is given by:

velocity = change of distance/ change of time

velocity = 3/6

velocity = 0.5 miles/minutes

From t=6 to t=10

As there is no change in distance, the velocity of the object is 0, it means Brianna is stationary from t=6 to t=10

From t=10 to t=16

Distance covered = 7 miles - 3 miles = 4 miles

Time taken = 16 - 10  = 6 minutes

Velocity = 0.67 miles/minutes

Answer:Brianna left home and drove 3 miles in 6 minutes. She then stopped for 4 minutes to pick up coffee. Finally, she traveled the last 4 miles in 6 minutes to arrive at her babysitting job.
