Answer 1

It will go like:

\[4(4+5) = 3(3+x)\]

Find x here..

Answer 2

Can you do the calculations here?

Answer 3

will x be 9

Answer 4

Yep..

Good..

Answer 5

i have another question

Answer 6

Okay, go ahead..

Answer 7

Find the midpoint of the segment connecting (4,7) to (-2,3).

Answer 8

Take the average of x coordinates...

Answer 9

What is average of 4 and -2?

Answer 10

is it 2

Answer 11

4-2 = 2..


But don't forget you will divide it again by 2.. as there are two observations..

Answer 12

\[x = \frac{x_1 + x_2}{2}\]

Answer 13

\[y = \frac{y_1 +y_2}{2}\]

Answer 14

is it (1,5)

Answer 15

@waterineyes how you find that 4(4+5)=3(3+x) ?

Answer 16

@mayliz

Answer 17

Answer 25

Use pythagorean theorem here..

Answer 26

\[c^2 = 5^2+9^2\]

Answer 27

Just take the square root, you forgot there..

Answer 28

i thought you would use
D= (x2 - x1)2 + (y2 - y1)2

Answer 29

Just one and the same thing.

Answer 30

You are forgetting square root there..

\[D = \sqrt{(x_2-x_1)^2 + (y_2 -y_1)^2}\]

Answer 31

the answer is 19

Answer 32

How??

Answer 33

J(-2,4) and K(5,-3)

Now, find the distance properly..

Answer 34

Sorry J(-4,2) and K(5,-3)..

Answer 35

13

Answer 36

Guessing??

Answer 37

Just use that formula buddy..

Where are you getting confused??

\(x_2 = 5, x_1 = -4, y_2 = -3, y_1 = 2\)

Answer 38

(-4,2) is 2 then you square root is which is 4

Answer 39

Nope..

Answer 40

Do, \((x_2-x_1)\) first..

What you got?
