15.9687194227 units between the 2 points

Answer:

The distance between the two points is 15 units

Step-by-step explanation:

the distance between (12, –7) and (–3, –7)

To find distance we use distance formula

Distance =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

(12, –7) is (x1,y1) and (–3, –7) is (x2,y2)

Now plug in the values in the formula

Distance =\sqrt{(-3-12)^2+(-7+7)^2}

Distance =\sqrt{(-15)^2+(0)^2}

Distance =15

The distance between the two points is 15 units

The midpoint of KL is M (-8,1). One endpoint is K (-6,5) find the coordinates of the other endpoint L
PSYCHO15rus [73]

Answer:

Midpoint (x , y) of two points is

( x1 + y1/2 , x2 + y2/2)

Midpoint of KL is M ( -8 , 1)

Let the coordinates of L be ( a , b)

From the above definition

Midpoint between K(-6 , 5) and

L ( a ,b) is

(-8 , 1) = ( -6+a/2 , 5+b/2)

Comparing first point with - 8

- 8 = -6 + a /2

Multiply through by 2

We get

-16 = - 6 + a

a = -16+6

a = - 10

Comparing the second point with 1

1 = 5+b/2

Multiply through by 2

2 = 5 + b

b = 2 - 5

b = -3

Therefore a = -10 and b = - 3

Hence the coordinates of

L is ( -10 , - 3)

Hope this helps

Using the slope formula, determine the slope of the two points.
Lelechka [254]
The slope formula is is rise over run or y2-y1/x2-x1

If you plug in those numbers you will get

(-1)-(-4)
———
1-(-2)

Simplify it and you get

3
— or 1
3

So the slope is 1

Rick buys 3 CDs and 5 video games. The cost of one video game is $12.00 more than the cost of one CD. If Rick spends $164.00, wh
Dmitry [639]

Step-by-step explanation:

x = price per video game

y = price per CD

164 = 5x + 3y

and then we know

x = y + 12

now we can use this as substitute in the first equation :

164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60

104 = 8y

y = $13

x = y + 12 = 13 + 12 = $25

so, each CD costs $13.
