A line passes through the point (5,-2) and has a slope of -1/3.Which equation models the line

Answer:

(-4,1)

Step-by-step explanation:

First, subtract 1-5. (When you move left or down you subtract. When you move right or up you add.) Left and right affect the x-axis

Second, subtract 4-3. Up and down Affect the y-axis

It would look like this:

(1,4)

=(1-5,4-3)

=(-4,1)

Step-by-step explanation:

The total number of flights delayed at several airport based on the histogram is 25.

An histogram is a graphical display of numerical data in the form of upright bars, with the area of each bar representing frequency.

Flight delayed 0 - 1 hour = 9

Flight delayed 1 - 2 hour = 3

Flight delayed 3 - 4 hour = 7

Flight delayed 4 - 5 hour = 5

Flight delayed 6 - 7 hour = 1

Total flights delayed = 9 + 3 + 7 + 5 + 1

= 25

Therefore, 25 flights were delayed.

Answer:

a) 2 minutes 48 seconds

b) The time would decrease as it takes less time for Lara to finish the race.

Step-by-step explanation:

Speed = Distance / Time

Speed = 475 / 114

Speed = 4.16m/s

Distance = 700m

Time = Distance/Speed

Time = 700/4.16

= 168 seconds

= 2 minutes and 48 seconds

Part a) The constant of variation is [tex]r=0.0567[/tex] or [tex]r=5.67\%[/tex]

Part b) [tex]I=\$662.03[/tex]

Step-by-step explanation:

Part a) Find the constant of variation.

we know that

The simple interest formula is equal to

[tex]I=P(rt)[/tex]

In this linear direct variation the constant r represent the constant of proportionality

Answer:

(8)(-4.5) would be your answer

The expression[tex]\(2n^{-4}\)[/tex] rewritten without a negative exponent is [tex]\(\frac{2}{n^4}\)[/tex]. This means the same as [tex]\(2\)[/tex] times the reciprocal of [tex]\(n\)[/tex] raised to the fourth power.

To rewrite the expression [tex]\(2n^{-4}\)[/tex] without using a negative exponent, we'll follow these steps:

1. Understand the Negative Exponent Rule: The rule states that [tex]\(a^{-b} = \frac{1}{a^b}\)[/tex]. It means that to convert a negative exponent to a positive one, you flip the base to the denominator of a fraction.

2. Apply the Rule to the Given Expression: We apply this rule to[tex]\(2n^{-4}\)[/tex].

3. Simplify the Expression: We simplify the expression to its final form without a negative exponent.

Let's apply these steps:

Step 1: Understand the Negative Exponent Rule

- The rule [tex]\(a^{-b} = \frac{1}{a^b}\)[/tex] tells us that to eliminate a negative exponent, we place the base with the positive exponent in the denominator of a fraction.

Step 2: Apply the Rule to the Given Expression

- Apply this to [tex]\(2n^{-4}\)[/tex]. It becomes [tex]\(2 \times \frac{1}{n^4}\)[/tex].

Step 3: Simplify the Expression

- Simplify [tex]\(2 \times \frac{1}{n^4}\)[/tex] to get the final expression.

Let's simplify it.

Step 3: Simplify the Expression

After applying the negative exponent rule to [tex]\(2n^{-4}\)[/tex], the expression simplifies to [tex]\(\frac{2}{n^4}\)[/tex].

Answer:

Volume of the sphere model of earth is 321m³

Step-by-step explanation:

Parameter given:

    diameter of the sphere = 8.5m

      π = 3.14

   Volume of a sphere is given as = 4/3 π r³

      Where r is the radius of the sphere.

  From given diameter, radius = 8.5/2 = 4.25m

Therefore, imputing the parameters in the formular we have:

                           ⇒4/3 × 3.14 × 4.25³

                            ⇒1.333 ×3.14 × 76.766

Volume of the sphere model = 321.31m³ ≅ 321m³

Answer: [tex]m=-\frac{4}{5}[/tex]

Step-by-step explanation:

To calculate  the slope of the line that has the coordinates given in the problem you must use the formula shown below:

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

Given the points  (-2, 7) (3 , 3), when you substitute them into the eequation shown above, you obtain that the slope is the following:

[tex]m=\frac{3-7}{3-(-2)}\\m=-\frac{4}{5}[/tex]

Answer:

[tex] - \frac { 4 } { 5 } [/tex]

Step-by-step explanation:

We are given the following two points on a line and we are to find the slope of this line:

(-2, 7) and (3,3)

We know the formula of the slope is given by:

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

Substituting the given coordinates in the above formula to get:

Slope = [tex] \frac { 7 - 3 } { -2 - 3 } = - \frac { 4 } { 5 } [/tex]

Answer:

Step-by-step explanation:

You need to change the denominator into a the least common denominator, 4 and 3 both have 12 in common. 12 is your new denominator but what you to the bottom you must do to the top. So when you multiply 3/4 by 3/3 you will get 9/12.

Then you want to make 4 1/3 into a improper fraction, which would be 13/3 you want to multiply this by 4 and you will get 52/12. You will then add 52/12 to 9/12 and get 61/12 or 5 1/12.

If you need any more help please let me know.

The answer is 1.

To find the answer you would take y/ x for the first thing in the table ( -2/1 ) then the second row of the table ( -1/2 ) then you would find out how much the points increased or decreased.

In this case y went up 1 and so did x so the slope would be 1/1 or just 1. Then check with the other points to make sure it is linear throughout then bam done. :)

The closest integers to -0.001 are 0 and -1. -0.001 lies just to the left of 0 on the number line, making 0 the nearest positive integer and -1 the nearest negative integer.

The two integers that are closest to -0.001 are 0 and -1. Since -0.001 is a negative number that is very close to zero, it lies between these two integers on the number line. The integer 0 is the closest on the positive side, and -1 is the closest on the negative side.

The LEFT side is the correct answer

Debits are entered on the left side of a T-account.

Debits and credits are fundamental concepts in accounting used to record financial transactions. In a T-account format, which visually splits an account into two sides, debits are always entered on the left side of the T-account. Conversely, credits are recorded on the right side.

For example, when a company purchases office supplies for cash, the office supplies account will have a debit entry (left side), while the cash account will have a credit entry (right side). This ensures that the accounting equation balances.

Step-by-step explanation:

Another way to think about this is to think "How many fourths are in 3".  There are 4 fourths in 1, and there are 3 1's in 3, so we have

3(4) = 12 fourths in 3

Algebraically you can write it as.

1(4)x = 3         this means "one fourth time some value is 3"  which is a rewording of what I explained above.  Solve for x by multiplying both sides by 4...we get x = 12, so

one fourth, 12 times gives us 3

The fraction 12/4 simplifies to 3 because the numerator and denominator can both be divided by their greatest common divisor, which is 4.

The question is related to the conversion of a fraction to a simpler form. The fraction 12/4 can be converted into a simpler form by dividing both the numerator and the denominator by their greatest common divisor. The greatest common divisor of 12 and 4 is 4. So, we can divide the numerator 12 and the denominator 4 by 4.

Here's how to do it:

As a result, the fraction 12/4 reduces to the whole number 3. Thus, 12 fourths is represented as 3 in its simplest form.

Answer: [tex]x^4+4x^3+6x^2+7x+2[/tex]

Step-by-step explanation:

To solve the exercise you must apply the following proccedure:

- Apply the distributive property.

- Keep on mind that when you multiply two powers with equal base, you must add the exponents.

- Add like terms.

Therefore, you obtain the following product:

[tex]=x^{(2+2)}+x^{(2+1)}+2x^2+3x^{(1+2)}+3x^{(1+1)}}+6x+x^{2}+x+2\\=x^4+x^3+2x^2+3x^3+3x^2+6x+x^2+x+2\\=x^4+4x^3+6x^2+7x+2[/tex]

The answer is: [tex]x^{4}+4x^{3}+6x^{2}+7x+2[/tex]

To find the product of the given expression, we need to apply the distributive property and then, group each like term.

The distributive property states that:

(a+b+c)(d+e+f)=a*d+a*e+a*f+b*d+b*e+b*f+c*d+c*e+c*f

Then, we have to group each like term. Like terms are the terms that have the same variable and exponent , for example:

[tex]x+x+x^{2}=2x+x^{2}[/tex]

For this case, the variable "x" has two Like terms, since both have the same exponent (1), then, we add each other in order to group term.

Also, we must remember the following power property:

Product of powers property,

[tex]a^{n}*a^{m}=a^{n+m}[/tex]

So, solving the product we have:

[tex](x^{2}+3x+1)(x^{2}+x+2)=x^{2}*x^{2}+x*x^{2}+2x^{2}+3x*x^{2}+3x*x+6x+x^{2}+x+2\\(x^{2}+3x+1)(x^{2}+x+2)=x^{2+2}+x^{1+2}+2x^{2}+3x^{2+1}+3x^{1+1}+6x+x^{2}+x+2\\(x^{2}+3x+1)(x^{2}+x+2)=x^{4}+4x^{3}+6x^{2}+7x+2[/tex]
