Slope between two points 12,6 and 20,22

1 answer:

7 0

Here's the official formula:
If you have two points :
L(a,b) and M(c,d)
slope=(d-b)/(c-a)
We have:
M(20,22) and L(12,6)
slope=(22-6)/(20-12)=16/8=2

Need #47 and #48 asap!! 20 pts!!

sergey [27]

Answer:

47-Step-by-step explanation:

X=121 because they are vertical angles

48- first divide 96 by 6 together the surface area of each side which is equal 16 then to find the length and the width find the square root of 16 which is 4 because it is a cube the length/width/height are all equal to four. So do 4 x 4 x 4 to find the volume of one cube. Which is equal to 64 then multiple by 8 to get the total volume 512cm^3

Use the distributive property to solve the equation 3x=15?

Tcecarenko [31]

Answer:

x = 5

Step-by-step explanation:

Ordinarily, one would not need the distributive property to solve this equation. It is quickly and easily solved by making use of the multiplication property of equality: multiply both sides of the equation by 1/3.

3x(1/3) = 15(1/3)

x = 5

___

To use the distributive property, we need the sum of two terms that have a common factor. We can get that form by subtracting 15 from both sides of the equation (subtraction property of equality):

3x - 15 = 15 - 15 . . . . subtract 15

3x -15 = 0 . . . . . . . . .simplify

Now, we can apply the distributive property to remove a factor of 3:

3(x -5) = 0

And we can use the multiplication property of equality to multiply by 1/3:

3(1/3)(x -5) = 0(1/3)

x -5 = 0 . . . . . . . . . . simplify

Finally, we can add 5 to both sides of the equation (addition property of equality):

x -5 +5 = 0 +5

x + 0 = 5 . . . . . . simplify

x = 5 . . . . . . . . . .simplify more

Step-By-Step Explanation:

i will go from 0 to 20:

0: 0

1: 1

2: 2

3: 3

4: 4

5: 5

6: 6

7: 7

8: 8

9: 9

10: A (10 is another 'digit')

11: B

12: 10 (12 = 1*12^1 + 0* 12^0)

13: 11 (13 = 1*12^1 + 1*12^0)

14: 12 (14 = 1*12^1 + 2*12^0)

15: 13

16: 14

17: 15

18: 16

19: 17

20: 18

Just remember to use the notation A and B after the digit nine, for example

22: 1A

23: 1B

24: 20

In other words, the answer is 0, 1 , 2, 3, 4, 5, 6, 7, 8, 9, A, B, 10, 11, 12, 13, 14, 15, 16, 17, 18
