Directed line segment porque is shown on the coordinate plane. What are the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1)?

Answers

Answer: (2,3).

Step-by-step explanation:

We need to find the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1).

Let the point be A.

[tex]PA:PQ=1:3[/tex]

[tex]PA:AQ=PA:(PQ-PA)=1:(3-1)=1:2[/tex]

It means the point A divide the segment PQ in 1:2.

Section formula: If a point divide a segment is m:n.

[tex]\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

[tex]A=\left(\dfrac{1(-2)+2(4)}{1+2},\dfrac{1(1)+2(4)}{1+2}\right)[/tex]

[tex]A=\left(\dfrac{-2+8}{3},\dfrac{1+8}{3}\right)[/tex]

[tex]A=\left(\dfrac{6}{3},\dfrac{9}{3}\right)[/tex]

[tex]A=\left(2,3\right)[/tex]

Therefore, the required coordinates are (2,3).

Solve for x in the equation: 5x +14 = 2x - 4





Someone help

Answers

Answer:

x = -6

Step-by-step explanation:

5x +14 = 2x - 4

Subtract 2x from each side

5x-2x +14 = 2x-2x - 4

3x +14 = -4

Subtract 14 from each side

3x+14-14 = -4-14

3x = -18

Divide each side by 3

3x/3 = -18/3

x = -6

Answer:

x = -6

Step-by-step explanation:

5x+ 14 = 2x - 4

-2x        -2x

3x+14= -4

   -14   -14

3x = -18

3x/3 = -18/3

Mount Kosciuszko is the highest mountain in Australia, with a peak of about 2,228 meters above sea level. Lake Erye has the lowest point at 15 meters below sea level. What is the difference in elevation between Mount Kosciuszko and Lake Eyre? You must show your work on your sheet on notebook paper.
A)2,243
B)2,213
C)2,250
D) 2,210​

Answers

Answer:

Option (A)

Step-by-step explanation:

Heights above the sea level are denoted with positive notations and depths below the sea level with negative.

Height of the highest peak of the mountain = +2228 meters

Lowest point of the lake = -15 meters

Difference between these elevations = 2228 - (-15)

                                                              = 2243 meters

Therefore, Option (A) will be the correct option.

Step-by-step explanation:

6x-2≥4x-6

6x-4x≥-6+2

2x≥-4

x≥-4÷2

x≥-2

Only -1 is greater than -2 in the list.

Answer:

x = - 1

Step-by-step explanation:

Given

2(3x - 1) ≥ 4x - 6 ← distribute parenthesis on left side

6x - 2 ≥ 4x - 6 ( subtract 4x from both sides )

2x - 2 ≥ - 6 ( add 2 to both sides )

2x ≥ - 4 ( divide both sides by 2 )

x ≥ - 2

The only value in the list greater than - 2 is - 1

x = - 1 is in the solution set

Serena estimates that she can paint 60 square feet of wall space every half-hour. Write an equation for the relationship with time in hours as the independent variable x and the square footage she can paint as the dependent variable y. Can she paint 400 square feet in 3.5 hrs

Answers

Answer:

So, the relationship with i hours as the indecent variables would be  

Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Step-by-step explanation:

Since we have given that

Area that she can paint = 60 square feet

Time taken = half hour = 30 minutes = 0.5 hours

Using "Unitary method, we get that

In 0.5 hours, she can paint = 60 square feet

In 1 hour, she can paint =  

In i hours, she can paint =  

Let the total area she can paint be 'y'.

So, the relationship with i hours as the indecent variables would be

Now,  Can Serena paint 400 square feet of wall space i. 3.5 hours

We put y = 400 and i = 3.5 hours to check whether it is equal or not.

Hence, Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Answer: I HOPE IT HELPS OR WATCH  VIDOES  ABOUT IT

Step-by-step explanation:

Two unique points define a line.  Other geometric figures also may pass through those two points (you will learn those later).

There are several forms of the equation of a line:

     Standard form                           Ax + By = C

     Slope-intercept form                  y = mx + b

     Point-slope form                        y – y1 = m(x – x1)

     Two-point form              y – y1 = [ (y2 – y1)/(x2 – x1) ](x – x1)

O.K., you picked the two-point form, right?    

               The points are  P1:  (5,5) and P2: (7,-4)

    y - 5 = [ ((-4) - 5)/(7 - 5) ] (x - 5)          (put in x and y values of points)

    y - 5 = [  -9 / 2 ](x - 5)                         (simplify)

    y - 5  =  -9/2x  + 45/2                           (distribute -9/2)

     y =  f(x) = -9/2x + 55/2                   (add 5 to both sided)

Check (very important):

  Is (5,5) on the line?      5 = (-9/2)(5) +  55/2  ?

                                         5 =  -45/2   +  55/2  ?

                                          5 =  10/2         yes.

  Is (7,-4) on the line?     -4 = (-9/2)(7) + 55/2       ?

                                          -4  =  -63/2   + 55/2   ?

                                          -4  =   -8/2   ?       yes.

On Gabriela's first birthday, her parents gave her a $50 savings account on every birthday after that her parents added to the account,
increasing the amount they deposited by $25 each year. Complete the recursive definition for the sequence that represents this situation by
finding the values for a, and d.

Answers

Initial amount , a = $50 .

Increase in price , d = $25 .

We need to find the recursive relation of the sequence .

If we notice it is an arithmetic progression with common difference $25 .

Which means that difference between any two consecutive term is 25 .

So , T(n) - T(n-1) = 25

T(n) = T(n-1) + 25 .

Hence , this is the required solution .
