B) {1,2,3,4}

Step-by-step explanation:

Since they are separate points and not on a function, you take the y value of each

Answer:

The rational numbers are a dense subset of the real numbers because every real number either is a rational number or has a rational number arbitrarily close to it.

Answer:

Informally, for every point in X, the point is either in A or arbitrarily "close" to a member of A — for instance, the rational numbers are a dense subset of the real numbers because every real number either is a rational number or has a rational number arbitrarily close to it (see Diophantine approximation).

Answer:

[tex] {r}^{2} + \: 2[/tex]

Step-by-step explanation:

Let the no. be r . It's square will be r^2 .

When r^2 is added with 2 , then it's sum is r^2 + 2

Answer:

(14, 9 )

Step-by-step explanation:

Given

[tex]\frac{x}{7}[/tex] + [tex]\frac{y}{3}[/tex] = 5 ( multiply through by 21 to clear the fractions )

3x + 7y = 105 → (1)

[tex]\frac{x}{2}[/tex] - [tex]\frac{y}{9}[/tex] = 6 ( multiply through by 18 to clear the fractions )

9x - 2y = 108 → (2)

Multiplying (1) by - 3 and adding to (2) eliminates the term in x

- 9x - 21y = - 315 → (3)

Add (2) and (3) term by term to eliminate x

- 23y = - 207 ( divide both sides by - 23 )

y = 9

Substitute y = 9 into either of the 2 equations and evaluate for x

Substituting into (1)

3x + 7(9) = 105

3x + 63 = 105 ( subtract 63 from both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Solution is (14, 9 )

Answer: [tex]t=5[/tex]

Add 8 to both sides

[tex]t-8+8=-3+8\\t=5[/tex]

Answer:

The correct answer is t = 5.

Step-by-step explanation:

To solve this question, we must first recognize that our goal is to get the variable t by itself.  To do this, we should add 8 to both sides of the equation to get rid of the -8 on the left side of the equation.  This is modeled below:

t - 8 = - 3

t - 8 + 8 = -3 + 8

t = 5

Therefore, the correct answer is t = 5.

If we want to check our answer, we can plug in 5 for t in the original equation.  If we do this, we get: 5 - 8 = -3, which is a true statement, so we know that we did the problem correctly.

Hope this helps!

Answer:

p =√(y+4)/3

Step-by-step explanation:

y=3p^2-4

so 3p^2=y+4

then p^2=(y+4)/3

so p =√(y+4)/3

Answer:

Step-by-step explanation:

y=3p^2-4

so 3p^2=y+4

then p^2=(y+4)/3

so p =√(y+4)/3

Answer:

Step-by-step explanation:

Temperature fell 25° [tex]\\[/tex]

5 PM => 20

10 PM => -5

Find the difference between both temperatures at 5 PM and 10 PM

T = 20 - ( -5) = 20 + 5 = 25

The reason we subtracted 10 PM from 5 PM (20 - ( -5)) and not the other way around is because 5 PM obviously comes before 10 PM.

Answer:

$700.8

Step-by-step explanation:

discount = 0.20

You actually pay full price (100% or 1) - discount (20% or 0.20), so 1 - 0.20 = 0.80

If the TV was originally $800, then you pay 0.80 (80%) of it, or

(800)(0.80) = $640.00 dollars.

Tax, 9.5% or 0.095, of $640 is added to the $640, so

Tax = 0.095 + 640 = $60.8

$60.8 + $640 = $700.8

Answer:

20480x^18

Step-by-step explanation:

first of all, solve 5(x^3)^2

(x^3)^2 means 3x2=6, so x^6. 5 times x^6 = 5x^6

(16x^4)^-3 = 1/4096x^-12

when theres a negative in exponent, make it 1/y.

when negative exponent appears in 1/y just flip it again to make it y. So...

5x^6 ( 4096x^12) = 20480x^18

hope this helps.

Answer:

67.5$

Step-by-step explanation:

75$ x .10 = 7.5$

75$ - 7.5$ = 67.5$

Answer:

$67.50

Step-by-step explanation:

First, find the discount.

Multiply the discount rate by the cost.

discount rate * cost

The discount rate is 10% and the cost is $75.

$75 * 10%

Convert 10% to a decimal. Divide 10 by 100 or move the decimal place two spots to the left.

10/100 = 0.10       or         10.0 --> 1.0 --> 0.10

$75 * 0.10

$7.5

Now, find the final price.

Since it is a 10% discount, we must subtract the discount amount from the cost.

cost - discount

The cost is $75 and the discount is $7.5

$75 - $7.5

$67.50

The final price of a item that costs $75 with a 10% discount is $67.50

Complete question is;

Sarah is expanding her landscaping business. She currently has three regions in which she provides landscaping services, and intends to increase that by two regions every month. Each region begins with eight clients, and she intends to increase the number of clients by three every month.

The estimate for the total number of clients is given by the expression below, where x is the number of months after Sarah begins the expansion.

6x² + 25x + 24

Use the information given to determine how best to complete the following sentences.

The constant of the expression represents the:

A.) increase in number of regions each month

B.) number of clients before the expansion

C.) maximum number of clients

D.) increase in the number of clients each month

The binomial (8 + 3x) is a factor of the expression, which represents the

A.) number of clients per region

B.) total number of clients

C.) total number of regions

per .

Answer:

A) Option B - number of clients before the expansion.

B) Option A - number of clients per region

Step-by-step explanation:

A) We are told that each region begins with eight clients, therefore it is a constant. Since she tends to increase this number by additional 3 each month, it means that this constant represents the number of clients before the expansion.

B) The binomial (8 + 3x) represents the new number of clients per region since each region begins with eight clients, and that she tends to increase this number by additional 3 each month.

Answer:

Your friends data

Step-by-step explanation:

The rule of statistics is: the more exact the data, the better.

Here it seems that you got less precise data, as you can see. This also causes the possibility of mistakes.

This is because when you have data that is more exact, you get a better estimation for mean, median, etc. This can help make patterns in your data.

This means that your friend had better data than you.

Answer:

12

Step-by-step explanation:

M is in the middle between S and T we know 2x+6 has to be the same as 3x+3 if 3x is one more x then 2x then we do 6-3 that eqauls 3 so X=3 and 2*3=6 and 6+6= 12.

Hey there! :D

Answer:

[tex]\huge\boxed{SM = 12}[/tex]

SM = 2x + 6

MT = 3x + 3

M is the midpoint of SM

Write an expression to represent the length of ST:

ST = SM + MT

ST = 2x + 6 + 3x + 3

Combine like terms:

ST = 5x + 9

Since ST = 2(SM), set up another equation:

5x + 9 = 2(2x + 6)

5x + 9 = 4x + 12

Isolate the "x" variable:

5x - 4x = 12 - 9

x = 3.

Substitute in this value of "x" into the equation for SM:

2(3) + 6 = 12.

Answer:

c=0

Step-by-step explanation:

3(c-1)+2(3c+1)=-(3c+1)

Distribute

3c -3 +6c +2 = -3c -1

Combine like terms

9c -1 = -3c -1

Add 1 to each side

9c = -3c

Add 3c to each side

12c = 0

Divide by 12

c = 0

Answer:

Step-by-step explanation:

3c-3+6c+2= -3c-1                                     ( 3c+6c =9c) and (-3+2 = -1) so

9c -1 = -3c-1  =       so add 3c to both sides to get rid of the  3c on the right side          

9c-1 +3c  = -3c +3c -1 =

12c-1 = -1       add +1 to both sides

12c-1 +1 = -1 +1

12c=0

c = 0/12

so c= 0

A graduated cylinder is basically a cylinder with little measurements on it.

If we drop the ball into the cylinder and the final volume in 29 instead of 20, this means that the ball has a volume of 9 mL as it took up 9mL of the water, pushing it up 9 mL.

Density is mass divided by volume. The ball has a mass of 27 g and a volume of 9mL. So, the density is 3 g/mL.

Have a wonderful day! :D

A prime number is a number whose only factors are one and itself. 5 is a prime number because the only whole numbers you can multiply to get 5 are 1 and 5.

Prime factorization is finding the prime numbers that multiply to make that number.

To do this, you see what numbers it divides by. 15 is divisible by 1, giving us 15. It is not divisible by 2, but it is divisible by 3, which gives us 5.

Now, we see if 3 and 5 can be factorized even more, but they cannot as they are both prime numbers. Therefore, the prime factorization of 15 is 3,5.

Have a wonderful day! :D

====================================================

Explanation:

Notice how the point to the very far right is an outlier. See the diagram below. The line of best fit in red goes through (or close to) the cluster of points to the left of this outlier location. It's not the best fit ever, but it's close enough. The drawing I did is my best guess. Without knowing the actual numbers, it's impossible to get the actual regression line.

The location of this outlier is (x,y) = (7,4). This means x = 7 and y = 4 pair up together. Since x is the width and x = 7, this means a width of 7 is an outlier.
