what property is
-2(x-y)=-2x+2y

Answer:

Base on the picture, if there are no other choices beside A,B,C then the correct answer would be C. The picture only shows the first two pairs of x and y and they are both proportional, but I'm unsure about the rest of the pairs in C because the picture got cut off.

A and B are incorrect because they do not represent a proportional relationship between x and y. If there are no other choices, then C would be more correct than A and B.

Answer:

14 videos

Step-by-step explanation:

4n=21+2.5n

1.5n=21

n=21/1.5

n=14

Answer:

14 Videos

Step-by-step explanation:

Let x be the number of videos rentable.

From the information given from the question, we know that:

Case A: Non-members

Cost to rent videos = $4x

Case B: Members

Cost to rent videos = $(21 + 2.5x)

So given from the question, we can use:

4x = 21 + 2.5x to solve for x.

[tex]4x = 21 + 2.5x \\ 4x - 2.5x = 21 + 2.5x - 2.5x \\ 1.5x = 21 \\ x = \frac{21}{1.5} \\ = 14[/tex]

The probability of getting-

Probability is the measure of how likely an event is to occur. Many events are impossible to predict to absolute certainty. We can only predict the possibility of an event occurring, i.e. how likely it is to occur, using it.

The formula for probability is;

Probability(event) = favourable outcome/ total outcome

Now, as per the given question;

There are 27 papers put in a hat numbering from 1 to 27.

The sample space will  be;

s = {1,,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27}

The total outcome is 27.

The total number of 12 digit in the sample space is 1.

Thus, the probability for getting slip 12 is;

Probability(slip 12) = 1/27

The sample space for even number are;

s = {2,4,6,8,10,12,14,16,18,20,22,24,26}

Now, there are total number of even digits in the sample space is 13.

Thus, the probability for getting even number is;

Probability(even) = 13/27.

The sample space for prime number are;

s = {2,3,5,7,11,13,17,19,23}

Noe, the total number of prime digits in the sample space is 9.

Thus, the probability for getting prime number is;

Probability(prime) = 9/27 = 1/3

Therefore, the probability for getting the prime number is 1/3.

4/5 divided by 4/3 is equal to 3/5.

In order to divide 2 fractions, we need to first flip the second fraction upside down and then multiply it with the other fraction.

Here, we need to simplify the following expression- 4/5 ÷ 4/3

As mentioned, here also we flip the fraction 4/3 ⇒ 3/4

Now, we multiply it with 4/5,

Thus 4/5 ÷ 4/3 becomes 4/5 × 3/4

now 4/5 × 3/4 = (4 × 3) / (5 × 4)

⇒ (4 × 3) / (5 × 4) = 12/20

Now, we convert this into a simplified fraction by dividing the numerator and denominator by 4. Thus, we get-

= 3/5

Thus, the value of the expression is 3/5.

Answer:

Length of the fence = 40 ft

Step-by-step explanation:

As the yard for the pet is square shaped with area 100 sq. ft, length of each side is given by  

             [tex]\sf side =\sqrt{area}\\\\ side = \sqrt{100}[/tex]

                    = 10 ft

Perimeter:

          Perimeter of square = 4 *side

                                              = 40 ft

If Moussa thinks of a number whose root is a multiple of 3, then there are many possible numbers, like 9, 36, 81, etc.

The numbers between 100 and 200 that have an integer square root are (121, 144, 169 and 196).

The number that Jiale thinks of is 64.

There are three separate, unrelated questions.

Firstly, Moussa thinks of a number whose root is a multiple of 3. Let us assume that the number is "y" and the concerned multiple of 3 be "3x" where (x = 1, 2, 3, 4, 5...)

Hence, as per the question statement,

[tex]\sqrt{y} =3x \\or, y = (\sqrt{y})^{2} =(3x)^{2} \\or,y=9x^{2}...(i)[/tex]

Using (x = 1, 2, 3, 4, 5...) in equation (i), we can have our possible set of answers, i.e., (9, 36, 81...)

Second, we are required to determine all the numbers between 100 and 200 that have an integer square root. We know that, [(10)² = 100]. Therefore, we will have to calculate the squares of numbers above 10 till the squared value reaches or crosses 200, i.e.,

[tex]11^{2}=121, (100 < 121 < 200)\\12^{2}=144, (100 < 144 < 200)\\13^{2}=169, (100 < 169 < 200)\\196^{2}=196, (100 < 196 < 200)\\15^{2}=225, (200 < 225)\\[/tex]

Hence, the numbers between 100 and 200 that have an integer square root are (121, 144, 169 and 196).

Third, Jiale thinks of a number whose square root of cube root is 2. Let the number be "z". As per question statement,

[tex]\sqrt{\sqrt[3]{x}}=2\\ or,(x^{\frac{1}{3}})^\frac{1}{2} =2\\or,(x)^(\frac{1}{3}*\frac{1}{2})=2\\or, (x)^\frac{1}{6}=2\\or,x=(2)^6\\or,x=64[/tex]

And to show that Jiale would have got the same number (2) by calculating the the square root first and then the cube root,

[tex]\sqrt{64} =8,\\\sqrt[3]{8}=2[/tex].

The exponential growth model for the future population is given as [tex]y = 1500(1.1)^{t}[/tex]   and the student population after 7 years is 2923.06.

The general expression for the exponential growth is given as :

                       [tex]y = a(1+r)^{t}[/tex]

where, a  = initial amount or current student population of Philadelphia

           r = rate

           t = time in years.

According to the question we have been given that

           a = 1500

           r = 0.1

putting the required values in above equation we get

                   [tex]y = 1500 (1+0.1)^{t}\\y = 1500(1.1)^{t}[/tex]

Hence the exponential growth model for the future population is given as :

                      [tex]y = 1500(1.1)^{t}[/tex]

For the population in 7 years is :

                      [tex]y = 1500(1.1)^{7}\\y = 1500*1.949\\y = 2923.06[/tex]

Step-by-step explanation:

The temperature values (y-axis) repeat every 12 months (x-axis).

If Tito took a loan of $10000 from a bank to be repaid within 4 years, at 12% Simple interest per annum, then, he will have to pay overall $4800 as interest to the bank over 4 years and a total payment of $14800 at the end of the 4th year to repay and close off the loan.

As per the question statement, a bank charges 12% Simple interest per annum on cash loans to its clients and Tito took a loan of $10000 from the same bank to be repaid within 4 years.

We are required to calculate the overall interest Tito has to pay to bank if he repays and closes the loan at the end of 4th year, and also to calculate the total payment required to repay and close off the loan at the end of the 4th year.

To solve this question, we need to know the formula to calculate the interest amount in case of simple interest which goes as

Interest (I) [tex]=(\frac{P*R*T}{100} )[/tex]

where, "P" = Principle amount of Loan,

"R" = Rate of simple interest charged on the principle per annum, and

"T" = Time period within which, the loan is to be repaid.

Here, (P = 10000), (R = 12%) and (T = 4). Then, the overall interest Tito will have to pay at the end of 4th year  = [tex](\frac{10000*12*4}{100}) = (100*12*4)=(48*100)=4800[/tex]

And total amount to be paid to repay and close of the loan at the end of 4th year will be = $[4800 + 10000] = $14800.

Answer:

Step-by-step explanation:

To subtract two fractions we need to have them have the same division by, which means the lower part of the fraction needs to be the same. To do that we would need to find a common denominator between 3 and 5, a number that can be both divided by 3 and 5. To figure common denominator for 5 and other nimbery just multiply the other number by 5: 3*5=15. so now we need to multiply both fractions by a number to get lower part to 15, so 4*3/5*3=12/15 and 1*5/3*5=5/15. Now we have 6 12/15 - 2 5/15 = 4 7/15.

Answer:

True

No solution

Step-by-step explanation:

The system of equations is

x + y +2 = 15      (1)
2x + 2 = 1           (2)
2y  - 2 = 7          (3)

Subtract 2 from both sides of Eq (2)

==> 2x + 2 - 2 = 1 - 2

==> 2x = -1

==> x = - 1/2 = - 0.5

Add 2 to both sides of Eq (3)

2y - 2 + 2  = 7 + 2

2y = 9

y = 9/2 = 4.5

Plug in values for  x and y in Eq (1)

x + y + 2 = 15 becomes

- 0.5 + 4.5 + 2 = 15

==> 6 = 15   which is false

This is an inconsistent system of equations. and therefore has no solution
