The midpoint is (10,9.5)
The one endpoint is (8,3)
All you have to do for this question is find out what you need to add to each coordinate to equal double the midpoint
For example
In this question the x coordinate is 10 so double 10 is 20
Then you do 20-8 which is 12
That is the x coordinate
The y coordinate is 9.5 so double that is 19
19-3=16 so the y coordinate is 16
The final answer is (12,16)

Answer:  v = (12,16)

Step-by-step explanation:

if the midpoint is (10,9.5)  and we know the coordinates of  U as (8,3) the we could  find the coordinates of  V using the formula

\frac{8+x}{2} =10    solve for x and x will be the x coordinate.

8+x = 20

-8         -8

x = 12  

\frac{3+y}{2} = 9.5    

3 + y = 19

-3           -3

y= 16

If x + 10 = 70, what is x?
seropon [69]

Answer:

C. 60

Step-by-step explanation:

x + 10 = 70

Subtract 10 from both sides

x + 10 - 10 = 70 -10

Simplifying

x = 60

Equivalent to x^3+3x^2-x+2x^2+6x-2 after it has been simplified
natima [27]

Answer:

x³ + 5x² + 5x - 2

Step-by-step explanation:

Given

x³ + 3x² - x + 2x² + 6x - 2 ← collect like terms

= x³ + (3x² + 2x² ) + (- x + 6x ) - 2

= x³ + 5x² + 5x - 2

Cheryl is moving to a new house. Her old house is 3 kilometers and 457meters from her new house. How many meters is her old hous
MrRissso [65]

Answer:

Her old house is 3000m+457m = 3457m from her new house.

Step-by-step explanation:

Conversion of units problems can always be modeled as a rule of three problem.

Rule of three problem:

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.

In the case of a conversion of units problem, the measures are:

- the value in one unit

- the value in another unit

As the value of the first unit increases, so will the value of the second unit. It means that in a conversion of units problem, we will always have a direct rule of three.

The problem states that Cheryl's new house  is 3 kilometers and 457meters from her old house. The problem wants to know this distance purely in meters, so we have to convert 3km to meters. 1km = 1000m, so:

1km - 1000m

3km - xm

x = 1000*3

x = 3000m

Her old house is 3000m+457m = 3457m from her new house.
