Answer:

(20,-4)

Step-by-step explanation:

We are given;

One end point as (2,5)

Point of division as (10,1)

The ratio of division as 4:5

We are required to calculate the other endpoint.

Assuming the other endpoint is (x,y)

Using the ratio theorem

If the unknown endpoint is the last point on the line segment;

Then;

\left[\begin{array}{ccc}10\\1\end{array}\right]=\frac{4}{5} \left[\begin{array}{ccc}x\\y\end{array}\right]+\frac{5}{9}\left[\begin{array}{ccc}2\\5\end{array}\right]

Therefore; solving the equation;

10=\frac{4}{9}x+\frac{10}{9}

solving for x

x = 20

Also

1=\frac{4}{9}y+\frac{25}{9}

solving for y

y= -4

Therefore,

the coordinates of the end point are (20,-4)

Solve the inequality. 9 + 9(x + 7) >= 36 The solution is
Alchen [17]

Answer:

x≥ -4

Step-by-step explanation:

9 + 9(x + 7)≥ 36

Subtract 9 from each side

9 -9+ 9(x + 7) ≥ 36-9

9(x + 7) ≥ 27

Divide each side by 9

9/9(x + 7) ≥ 27/9

x+7≥ 3

Subtract 7 from each side

x+7-7 ≥ 3-7

x≥ -4

A carton can hold 1,000 unit cubes that measure 1 inch by inch.describe the dimensions of the carton using unit cubes
Romashka-Z-Leto [24]
You've told us the volume of the carton. 
That doesn't tell us the dimensions.

If the unit cubes have to exactly fit the dimensions,
then all we know is that the dimensions are integers,
and their product is 1,000.

The carton could be

1 by 1 by 1,000
1 by 2 by 500
1 by 4 by 250
1 by 5 by 200
1 by 8 by 125
1 by 10 by 100
1 by 20 by 50
1 by 25 by 40

2 by 2 by 250
2 by 5 by 100
2 by 10 by 50
.
.
and several other possible sets.

PLEASE HELP ME!!!!! I HAVE TRIED THIS QUESTION 5X ALREADY AND I STILL CANNOT GET THE RIGHT ANSWER!!! I KNOW THE ANSWER BUT I HAV
kirill [66]

Answer:

x = 3 and y = 2

or

(3,2)

Step-by-step explanation:

first equation (LCM = 3 x 4 x 5 = 60)

(x+2)/5 - (9-x)/3 = (y - 6)/4

12(x+2) - 20(9-x) = 15(y - 6)

12x + 24 - 180 + 20x = 15y - 90

32x - 15y = -90 - 24 + 180

32x - 15y = 66

second equation:

8(x + 2) - (2x + y) = 2(x + 13)

8x + 16 - 2x - y = 2x + 26

6x - y + 16 = 2x + 26

4x - y = 10

Now you have 2 equations:

4x - y = 10  ---> y = 4x - 10

32x - 15y = 66

Substitute   y = 4x - 10 into 32x - 15y = 66

32x - 15(4x - 10) = 66

32x - 60x + 150 = 66

-28x = -84

    x = 3

    y = 4(3) - 10

    y = 12 - 10

    y = 2

Solutions: x = 3 and y = 2
