One endpoint of a line segment is (–6, 4), and the midpoint of the segment is (–2, 7). What are the coordinates of the other end
Arturiano [62]

Answer:

A. (2, 10)

Step-by-step explanation:

If there are two points (x1,y1) and (x2,y2) on a coordinates plane then

coordinates of the midpoint is given by (x1+x2)/2, (y1+y2)/2

__________________________________________________

Given

one endpoint is (–6, 4) and midpoint is (–2, 7)

let coordinates of other endpoint be (x,y)

now if one endpoint is (–6, 4) and other endpoint is (x,y)

then coordinates of midpoint is ((-6+x)/2 , (4+y)/2)

while the coordinates of midpoint given  is  (–2, 7)

thus (–2, 7) should be equal to ((-6+x)/2 , (4+y)/2)

-2 = (-6+x)/2             and   7 = (4+y)/2

=> -2*2 = -6+x                 => 7*2 = 4+y

=> -4 = -6+x                    => 14 = 4+y

=> -4+6 = x                     => 14-4 = y

=> x = 2                           => 10 = y

Thus, coordinates of the other endpoint is(2,10)

Solve for x. Show each step please . Circle your final answer. <br> 2(8-12x)+8x= -25x+52
Vera_Pavlovna [14]

Answer:

x = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(8−12x)+8x=−25x+52

(2)(8)+(2)(−12x)+8x=−25x+52(Distribute)

16+−24x+8x=−25x+52

(−24x+8x)+(16)=−25x+52(Combine Like Terms)

−16x+16=−25x+52

−16x+16=−25x+52

Step 2: Add 25x to both sides.

−16x+16+25x=−25x+52+25x

9x+16=52

Step 3: Subtract 16 from both sides.

9x+16−16=52−16

9x=36

Step 4: Divide both sides by 9.

9x/9 = 36/9

x = 4

Yesterday 270 concert tickets were sold. today 216 were sold. what is the percent of change
UNO [17]
Given:
yesterday = 270
today = 216

yesterday's number of tickets sold is the basis of the percent of change. So, 270 is the 100%.

270 - 216 = 54  * value of the change in ticket sales

54/270 = 0.20 x 100% = 20%  * percent of change

There was a 20% decrease in ticket sales.
