2 matches with c. ( the x coordinates stay the same , y changes sign)

3 matches with e  ( both coordinates are  multiplied by 2)

4 matches to d.

Answers

Answer: -4

Step-by-step explanation:

This means we want to find where y=0.

This is at point A, since it has coordinates (-4, 0).

Since A has an x coordinate of -4, f(-4)=0.

C = b - a
a = 6 correct to the nearest integer
b = 15 correct to the nearest 5.

Can someone help me solve y 12 + y = 4x

Answers

Answer: Y = 4x - 12

Step-by-step explanation:

Well, the reason for this is because y can be anything because there are 2 unknown terms in the equation. Thus, the answer to y can be many different answers. The one common thing that all of these answers have is that they have only 1 expression (An equation without equal sign) to solve it. This expression is the answer to y, but it can be changed judging by the answer of x. That is why you cannot determine an exact answer to y with there being many, so you have to write the expression to get y. Which you can find out by:

12 (Part) + y (Part) = 4x (Whole)

So to figure out one part do the whole minus the other part which is why 4x is our answer:

4x (Whole) - 12 (Other Part)

This is called part-whole postulate.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that seiko deposits $3500 into an account that pts 5.8% annual interest monthly.

We need to find the balance after 8 years.

[tex]A=Pe^{rt}[/tex]

P is the principle amount which is 3500

r is rate of interest =5.8%=5.8/100=0.058

t is the time period=8 years

[tex]A=3500e^{0.058(8)}[/tex]

[tex]A=3500e^{0.464}[/tex]

A=3500(1.59)

A=5565

Combine the like terms to simplify the expression. 9x2 + 3y2 + 6y2 – x

Step-by-step explanation:

Combining like terms

-9x is a different term than 9x^2 however 9x is like terms with x. Coefficients really are the only thing that are excused for like terms

Now with that out of the way,

1 - Rewrite

9x²+3y²+6y²-x

This step becomes more useful as you go on in algebra as organization will soon start to correlate how fast you complete problems correctly

2 - Find like terms

9x² does not have any like terms

-x does not have a like term

3 - Combine like terms

At an international conference, flags from 12 different countries will be displayed. Of these flags, 6 are from the continent of South America and 6 flags are from the continent of Europe. The flags will be displayed in a row, alternating between continents. A flag from South America will be in the first position. In how many ways can the flags be displayed?

Answers

Using the Fundamental Counting Theorem, it is found that the flags can be displayed in 518,400 ways.

What is the Fundamental Counting Theorem?

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

In this problem, we have that odd positions get South American countries, hence:

[tex]n_1 = 6, n_3 = 5, n_4 = 3, \cdots, n_11 = 1[/tex]

Even positions get European countries, hence:

[tex]n_2 = 6, n_4 = 5, \cdots, n_12 = 1[/tex]

Hence, since the number of ways for both the South American and European countries is the factorial of 6, we have that:

N = 6! x 6! = 518,400

The flags can be displayed in 518,400 ways.

What are Linear Equations?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution

On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.

Given data ,

Let the linear function be represented as A

Now , the value of A is

y = 2x + 3

when the input values of the equation are x = { -2 , -1 , 0 , 1 , 2 , 3 }

The output values are

when x = -2

y = 2 ( -2 ) + 3

y = -1

On simplifying , we get

y = { -1 , 1 , 3 , 5 , 7 , 9 }

Hence , the table of values are solved

Solve 2x + 3y = 16
4x+10y = 40​

Answers

Answer:

x = 5, y = 2

Step-by-step explanation:

First, find the value of x in respect to y:

2x + 3y = 16
2x = 16 - 3y

x = 8 - 3/2y

Then, substitute this expression into the second equation (Since we've established x is equal to 8 - 3/2y, we can put that in place of x):

4(8 - 3/2y) + 10y = 40

Then, distribute and solve for y:

32 - 6y + 10y = 40
32 + 4y = 40
4y = 8
y = 2

Now that we know what y equals, we can substitute the value of y in the equation to find x:
2x + 3(2) = 16
2x + 6 = 16
2x = 10

x = 5

Find the value of n so that the line perpendicular to y=−15x − 6 passes through the points (n, −12) and (4, 8) .

Answers

Answer:

[tex]n = 304[/tex]

Step-by-step explanation:

Given

[tex]y = -15x - 6[/tex]

[tex]Points: (n,-12) \& (4,8)[/tex]

Required

Determine the value of n

First, we need to determine the slope of the given equation.

An equation is of the form;

[tex]y = m_1x + b[/tex]

Where m = slope.

By comparison.

[tex]m_1 = -15[/tex]

Since the given point and the given equation are perpendicular, then:

[tex]m = -\frac{1}{m_1}[/tex]

[tex]m = -\frac{1}{-15}[/tex]

[tex]m = \frac{1}{15}[/tex]

The slope of the point is calculated as thus:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (n,-12)[/tex]

[tex](x_2,y_2) = (4,8)[/tex]

[tex]m = \frac{1}{15}[/tex]

So, we have:

[tex]\frac{1}{15} = \frac{8 - (-12)}{4 - n}[/tex]

[tex]\frac{1}{15} = \frac{8 +12}{4 - n}[/tex]

[tex]\frac{1}{15} = \frac{20}{4 - n}[/tex]

Cross Multiply

[tex]4 - n = 20 * 15[/tex]

[tex]4 - n = 300[/tex]

Solve for n

[tex]n = 4 + 300[/tex]

[tex]n = 304[/tex]

This is because the product of the two prime numbers are divisible by those two numbers, therefore going against the definition of a prime number. For example 3 and 5 are prime numbers and their product is 15. 15 can be divided by 3 and 5 so it is not a prime number.
