To find a line that is parallel to another line and passes through a specific point, you first find the slope of the original line. Then, you use the point-slope form of a line equation to find the equation of the new line. The final equation is y = 5/3x - 10.

In order to find the equation of a line that is parallel to another and passes through a specific point, you first need to find the slope of the original line. The line given in the question is 5x - 3y = 6, which can be rearranged into slope-intercept form (y = mx + b) to become y = 5/3x - 2. The slope (m) of this line is 5/3. Parallel lines share the same slope, so the slope of the line we are trying to find is also 5/3.

Next, we use the point-slope form of a line equation, which is y - y1 = m(x - x1). The point given in the question is (6, -2), so x1 = 6 and y1 = -2. Substituting these into the equation, we find the equation of the line to be y + 2 = 5/3(x - 6).

Simplify this to y = 5/3x - 10, which is the equation of the line parallel to the given line and passing through the point (6, -2).

To find an equation of a line parallel to a given line that passes through a specific point, you can use the point-slope form of a line. Find the slope of the given line, and use the slope and the given point to determine the equation of the parallel line.

We can find the equation of a line parallel to the given line by using the fact that parallel lines have the same slope. To find the slope of the given line, we need to rearrange the equation into the slope-intercept form, y = mx + b, where m is the slope:

5x - 3y = 6 → -3y = -5x + 6 → y = (5/3)x - 2

So, the slope of the given line is 5/3. Thus, any line parallel to this must also have a slope of 5/3.

Since we now have the slope and a point that the line passes through (6, -2), we can use the point-slope form of a line to find the equation:

y - y₁ = m(x - x₁) where (x₁, y₁) is the point given and m is the slope. Substituting the values in, we get:

y - (-2) = (5/3)(x - 6) → y + 2 = (5/3)(x - 6)

Simplifying this equation gives the final answer:

y = (5/3)x - 22/3

Step-by-step explanation:

A point has zero dimension, once two pints are connected then you get one dimension which is a line

B. False

A point is a fundamental concept in geometry and represents a location in space. It is considered zero-dimensional because it has no length, width, or height.

A point is often represented by a dot or a small symbol and is described by its coordinates in a coordinate system.

In a one-dimensional context, you would have a line segment or a line that consists of multiple points.

However, a single point on its own is considered to have no dimension and is therefore not classified as one-dimensional.

Answer:

[tex]a_n=42n-621[/tex]

Step-by-step explanation:

This is arithmetic sequence so you should go to linear equations in your head.

Think of the question asking you to find the equation of line going through the points:

(14,-33) and (15,9).

First, let's find the slope.

You need to compute y's change over x's change.

The way I like to do that is line up the points vertically, subtract them, and then put 2nd difference over first.

Like this:

(  15  ,   9)

-(  14  ,  -33)

------------------

   1         42

So the slope is 42/1=42.

(The slope is our common difference.)

Now point slope form is:

y-y1=m(x-x1) where m is the slope and (x1,y1) is a point you know on the line.

So we have m=42 and (x1,y1)=(15,9).  (You could have chose the other point.)

y-9=42(x-15)

I'm going to put in slope-intercept form.  Slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

y-9=42(x-15)

Solve for y by adding 9 on both sides:

y=42(x-15)+9

Distribute 42 to terms in the ( ) :

y=42x-42(15)+9

y=42x-630+9

y=42x-621

So we can which back to n now:

Answer:

Step-by-step explanation:

According to the given statement two pieces are of same length:

If the length of one piece is x,

Then the length of other piece is also x.

And one piece is 2 feet longer than the other two = x+2

Total length of a board = 10 foot

Now make the equation from these terms:

x+x+x+2= 10

This is the equation of the given question.

You can further solve this equation:

x+x+x+2=10

3x+2=10

Now combine the constants:

3x=10-2

3x=8

x=8/3

x=2.67

It means that the length of two pieces of same length is 2.67

And the length of one piece which is longer than the other two = x+2 = 2.67+2 = 4.67 ....

Final answer:

To cut a 10-foot board into three pieces where two are the same length and one is 2 feet longer, denote the shorter length as 'x', create the equation 2x + (x + 2) = 10, and solve for 'x'. The two shorter pieces will each be approximately 2.67 feet and the longer one will be approximately 4.67 feet.

Explanation:

The question involves dividing a 10-foot board into three pieces with one piece being 2 feet longer than the other two equal pieces. To solve this, let's denote the length of the shorter pieces as 'x'. Since there are two of these, we have '2x', and the longer piece would be 'x + 2' feet long. The sum of the lengths of all three pieces is equal to the length of the board, so:

2x + (x + 2) = 10

This simplifies to:

3x + 2 = 10

Subtracting 2 from both sides gives:

3x = 8

Dividing both sides by 3 gives:

x = 8/3 or approximately 2.67 feet.

Therefore, the two shorter pieces are each approximately 2.67 feet long and the longer piece is 2.67 + 2, which is approximately 4.67 feet long.

Eating dinner and eating dessert are dependent events because

P(dinner) . P(dessert) = 0.9 × 0.6 = 0.54 which is not equal to

P(dinner and desert) = 0.5 ⇒ answer A

Step-by-step explanation:

* Lets study the meaning independent and dependent probability  

- Two events are independent if the result of the second event is not

  affected by the result of the first event

- If A and B are independent events, the probability of both events  

 is the product of the probabilities of the both events

- P (A and B) = P(A) · P(B)

* Lets solve the question  

∵ There is a 90% chance that a person eats dinner

∴ P(eating dinner) = 90/100 = 0.9

∵ There is a 60% chance a person eats dessert

∴ P(eating dessert) = 60/100 = 0.6

- If eating dinner and dating dessert are independent events, then

 probability of both events is the product of the probabilities of the

 both events

∵ P(eating dinner and dessert) = P(eating dinner) . P(eating dessert)

∴ P(eating dinner and dessert) = 0.9 × 0.6 = 0.54

∵ There is a 50% chance the person will eat dinner and dessert

∴ P(eating dinner and dessert) = 50/100 = 0.5

∵ P(eating dinner and dessert) ≠ P(eating dinner) . P(eating dessert)

∴ Eating dinner and eating dessert are dependent events because

  P(dinner) . P(dessert) = 0.9 × 0.6 = 0.54 which is not equal to

  P(dinner and desert) = 0.5

Answer:

t=0                                  t = -10/3

Step-by-step explanation:

5|3t+5|=25

Divide each side by 5

5|3t+5| /5=25/5

|3t+5|=5

Now to get rid of the absolute value we get two equations, one positive and one negative

3t+5 =5           3t+5 = -5

Subtract 5 from each side

3t+5-5 =5-5           3t+5-5 = -5-5

3t =0                        3t = -10

Divide by 3

3t/3 = 0/3                   3t/3 = -10/3

t=0                                  t = -10/3

Answer:

Step-by-step explanation:

From any point (x, y ) on the parabola the focus and directrix are equidistant

Here the focus = (- 6, 0) and the directrix is x = 6

Using the distance formula

[tex]\sqrt{(x+6)^2+(y-0)^2}[/tex] = | x - 6 |, that is

[tex]\sqrt{(x+6)^2+y^2}[/tex] = | x - 6 |

Squaring both sides

(x + 6)² + y² = (x - 6)² ← distribute factors on both sides

x² + 12x + 36 + y² = x² - 12x + 36

Subtract x² - 12x + 36 from both sides

24x + y² = 0 ( subtract y² from both sides )

24x = - y² ( divide both sides by 24 )

x = - [tex]\frac{1}{24}[/tex] y² → D

Answer:

The percentage of the calls lasted less than 8 min is 16%

Step-by-step explanation:

* Lets explain how to solve the problem

- To find the percentage of the calls lasted less than 8 min, find the

  z-score for the calls lasted

∵ The rule of z-score is z = (x - μ)/σ , where

# x is the score

# μ is the mean

# σ is the standard deviation

* Lets solve the problem

- The average phone call in a certain town lasted is 9 min

∴ The mean (μ) = 9

- The standard deviation is 1 min

∴ σ = 1

- The calls lasted less than 8 min

∴ x = 8

∵ z = (x - μ)/σ

∴ z = (8 - 9)/1 = -1/1 = -1

∴ P(z < 8) = -1

- Use z-table to find the percentage of x < 8

∴ P(x < 8) = 0.15866 × 100% = 15.87% ≅ 16%

* The percentage of the calls lasted less than 8 min is 16%

Answer:

The percentage of the calls lasted less than 8 min is 16%.

Step-by-step explanation:

We are dealing with a normal distribution with an average phone call of 9 min and a standard deviation of 1 min. Below we can observe the empirical rule applied with a mean of 9 and a standard deviation of 1. The number 8 represents one standard deviation below the mean, so, the percentage of observations below 8 is 16%. Therefore the percentage of the calls lasted less than 8 min is 16%.

Please look at the different answers. I wasn't 100% sure what your expression was.

Step-by-step explanation:

If you mean 2/(5x-1) then g(x) will take the fraction into account with a constant 2 for the numerator and a variable for the denominator since that is where our variable is so g(x)=2/x.

Now h(x)=5x-1 since if you plug in 5x-1 into 2/x where x is you will get our original expression.

Now if you did mean (2/5)x-1 I would take notice of where the variable is which is in (2/5)x so g(x)=x-1 where h(x)=(2/5)x since if you plug (2/5)x in place of the x in x-1 you will get the original.

Used the concept of composition which states that,

The composition of a function is an operation where two functions say f and g generate a new function say h in such a way that;

[tex]\ h (x) = g (f (x))[/tex]

Consider the given function as

[tex]f (x) = \dfrac{2}{5} x - 1[/tex]

It is given that [tex]\ f (x) = g (h (x))[/tex] and neither [tex]g (x)[/tex] nor [tex]h (x)[/tex] is solely x.

Let us assume that,

The function h (x) is defined as,

[tex]h (x) = \dfrac{2}{5} x[/tex]

Then we get;

[tex]\ f (x) = g (h (x))[/tex]

= [tex]h (x) - 1[/tex]

Substitute [tex]h (x) = x[/tex] in the above function for the value of function g (x),

[tex]g (x) = x - 1[/tex]

Answer:

-$1.9

Step-by-step explanation:

There are 47 pages.

Printing on both sides would divide the number of pages into half.

47/2 = 23.5

2 pages on each side would mean 4 pages on one sheet. Therefore, the number of pages will be further divided by 2.

23.5/2 = 11.75

There cannot be 11.75 pages so we will round it up to 12 pages.

Each page costs $0.25 so 12 pages will cost:

12 x 0.25 = $3

Faithi has $1.1 so new account balance will be:

1.1 - 3 = $-1.9

Therefore, Fathi's balance in his printing account would be negative $1.9.

!!

When Fathi prints a 47-page document using both sides of pages and printing 2 pages on each side, at a cost of $0.25 per sheet, his printing account balance will be -$1.90.

The question asks what will Fathi's balance be in his printing account after printing a document that is 47 pages long, with specific printing constraints. To solve this, we first need to figure out the number of pages he will print per sheet. Given that Fathi prints two pages on each side of a sheet, he will print 4 pages per sheet. As the document is 47 pages, he will need a total of 12 sheets (47 divided by 4 and rounded up to the nearest whole number).

Next, we need to calculate the cost of printing those sheets. As each sheet reduces his printing account by $0.25, and he's using 12 sheets, the cost will be $3.00 (12 multiplied by $0.25).

Finally, to find the balance in his printing account, we subtract the cost of printing from his initial balance. Fathi started with $1.10 in his printing account, so after deducting the cost of printing 12 sheets, his final balance will be $-1.90 (which means he owes this amount to replenish his account back to zero).
