Answer 1

Answer:

c

Step-by-step explanation:

just plug each coordinates

5=x

18=y

if its tru for both then thats the answer

Answer 2

Answer:

5,8

Step-by-step explanation:

y=4x-2-----(i)

y=x+13----(ii)

Equating equation i and ii we get,

[tex]4x - 2 = x + 13[/tex]

[tex]4x - x = 13 + 2[/tex]

[tex]3x = 15[/tex]

[tex]x = 3[/tex]

[tex]substitutin \: the \: value \: of \: x \: in \: equation \: (i)[/tex]

[tex]y = 4x - 2[/tex]

[tex]y = 4 \times 5 - 2[/tex]

[tex]y = 20 - 2[/tex]

[tex]y = 18[/tex]

Marks this as a brainest answer ok.

Answer:

a) [tex]y=1[/tex]

b) [tex]x=-3[/tex]

Step-by-step explanation:

Recall the forms of vertical and horizontal lines

Horizontal lines come in the form of [tex]y=0x+b[/tex], so the slope of the equation is zero. The value of b will be the y-value of the point that  you're given.

This means that the equation for a would be y=1

Vertical lines come in the form of [tex]x=a[/tex]. For this line, the value of a would be equivalent to the x-value of the given point. Therefore, b. would be [tex]x=-3[/tex]

On a number line where is the number 14 relative to the number -23

Answers

Answer:

14 is to the right of -23

Step-by-step explanation:

On the number line, the number 14 will appear on the right side of -23 with respect to zero from front.

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series.

Number line is a graphical representation of whole numbers, natural numbers, rational and irrational numbers. which represents both negative and positive numbers such that, positive numbers from 1 to infinity lie on the right-hand side of zero and negative numbers from (- 1) to (- infinity) lie on the left-hand side of zero.

Therefore, zero is considered as the reference point.

Number 14 is positive natural number, it appears on the right side of zero and (-23) appears on the left side of zero.

Thus, On a number line, the number 14 lies to the right of number -23.

Simplify 3 + (b + 8) = 3 + (8 + b)

Answers

Answer:

−3b /8

​  

 

Step-by-step explanation:

Answer:

b + 11 = 11 + b

Step-by-step explanation:

Combine like terms. Note that because you are adding for all terms, you can technically disregard the parenthesis:

3 + (b + 8) = b + 3 + 8 = b + 11

3 + (8 + b) = 3 + 8 + b = 11 + b

b + 11 = 11 + b (True).

The US courts are reviewing a case to see whether a work has been refused fairly. What is an example of something they might consider when trying to decide whether the use was fair?

Answers

Answer:

The Purpose and Character of the usage of the work.

Step-by-step explanation:

In the United States of America, there is a terminology used in court called Fair use. This is a law in the USA that permits a limited use of one or more copyrighted materials without the need to first acquire permission from the holder of the copyright.

Thus, an example of something they might consider when trying to decide whether the use was fair is:

The Purpose and Character of the usage of the work.

This is because the original purpose of the work may have been altered to mean something new or different or it was just copied exactly into another work.

So knowing the purpose and character of usage of the work or material in question would be something they would consider

Fractions are three types proper, improper and mixed fraction

A proper fraction is a fraction which has its numerator value less than the denominator.

A improper fraction is a fraction which has its numerator value greater than the denominator.

A fraction represented with its quotient and remainder is a mixed fraction.

[tex]2\frac{1}{3}[/tex] is a mixed fraction

Answers

Answer:

2 (5 x - 2) = 10 x - 4 or x = 2/5 (if you need to solve for x)

Step-by-step explanation:

Simplify the following:

4 x - 2 + 6 x - 2

Hint: | Group like terms in 4 x - 2 + 6 x - 2.

Grouping like terms, 4 x - 2 + 6 x - 2 = (4 x + 6 x) + (-2 - 2):

(4 x + 6 x) + (-2 - 2)

Hint: | Add like terms in 4 x + 6 x.

4 x + 6 x = 10 x:

10 x + (-2 - 2)

Hint: | Group the negative terms in -2 - 2 together and factor out the minus sign.

-2 - 2 = -(2 + 2):

10 x + -(2 + 2)

Hint: | Evaluate 2 + 2.

2 + 2 = 4:

Hint: | Factor out the greatest common divisor of the coefficients of 10 x - 4.

Factor 2 out of 10 x - 4:

Answer: 2 (5 x - 2)

if you need to solve for x then:

Solve for x:

10 x - 4 = 0

Add 4 to both sides:

10 x + (4 - 4) = 4

4 - 4 = 0:

10 x = 4

Divide both sides of 10 x = 4 by 10:

(10 x)/10 = 4/10

10/10 = 1:

x = 4/10

The gcd of 4 and 10 is 2, so 4/10 = (2×2)/(2×5) = 2/2×2/5 = 2/5:

what's the solution of the equation 4[x+2(3x-7)]=22x-65

Answers

Answer:

x = -3/2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(x+2(3x−7))=22x−65

Step 1: Simplify both sides of the equation.

4(x+2(3x−7))=22x−65

(4)(x)+(4)(2(3x−7))=22x+−65(Distribute)

4x+24x+−56=22x+−65

(4x+24x)+(−56)=22x−65(Combine Like Terms)

28x+−56=22x−65

28x−56=22x−65

Step 2: Subtract 22x from both sides.

28x−56−22x=22x−65−22x

6x−56=−65

Step 3: Add 56 to both sides.

6x−56+56=−65+56

6x=−9

Step 4: Divide both sides by 6.

6x = -9

A message can follow different paths through servers on a network. The sender’s message can go to one of five servers for the first step; each of them can send to five servers at the second step; each of those can send to four servers at the third step; and then the message goes to the recipient’s server.
a. How many paths are possible?
b. If all paths are equally likely, what is the probability that a message passes through the first of four servers at the third step?

Answers

Answer:

Number of way s= N=100

The probability that it passes through  first of four servers at the third step is 0.25

Step-by-step explanation:

The total number of possible ways can be found out by multiplying the possibilities so the possibilities at the

1st stage is  5

2nd stage is 5

3rd stage is  4

4th stage is 1

So Number of way s= N= 5*5*4= 100

This can be solved by drawing a tree diagram as well.

Now the probability of finding the  that a message passes through the first of four servers at the third step.

There are five paths

And we have to find the probability of four

So 5C1*5C4/100= 0.25

The probability that it passes through  first of four servers at the third step is 0.25

For an apartment complex, the association collects $158,000 from all of its 211 residents. What is the average rent per capita for this apartment complex?

Answers

Answer:

$748.42

Step-by-step explanation:

The average rent per capita is used to measure the average rent paid by a group of people in an apartment or an area. The rent per capita estimates the average rent charged for each resident. It is ratio of the total rent paid by the people in the area to the number of residents. Hence:

The average rent per capita = Total rent / number of residents = $158000 / 211 residents = $748.42
