How do you find slope

Mathematics

The slope is the change in Y divided by the change in X.

You would need to know the coordinates of 2 points ( X1,Y1) and (X2,Y2), then subtract : Y2 - Y1 divided by X2- X1.

In order to find slope, you put have four points (x1, y1), (x2, y2). Your formula will be m = (y2-y1) / (x2-x1). Your (y2, y1) will be on top while (x2, x1) will be on the bottom. I hope that is the right formula you need. I always use it and it works for me. Have a great day!! :)

Besties pls help!!!!<br><br> 8) In the diagram below, what is the m measure of R.
Dafna1 [17]

Let's see what we can fill in here.

<ACE = 130

180 - 50 = 130

Now that we have two sides and an included angle, we can use the Law of Cosines.

Law of Cosines: c^2 = a^2 + b^2 - 2ab(cos(C))

Let's plug in what we know and solve!

c^2 = 40^2 + 38^2 - 2(40)(38)(cos(130))

R = 70.69706

Hope this helps!! :)

Question
maria [59]

Answer:

He needs 16 ounces of raisins and 8 ounces of nuts

Step-by-step explanation:

Let

x -----> the number of ounces of raisins

y -----> the number of ounces of nuts

we know that

x+y=24 -----> equation A

x=2y -----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

(2y)+y=24

3y=24

y=8 ounces of nuts

Find the value of x

x=2(8)=16 ounces of raisins

therefore

He needs 16 ounces of raisins and 8 ounces of nuts

Help!! Please!!!!!

Answer:

the mean is 8 and the absolute deviation is 1.5

Step-by-step explanation:

to find the mean you add up all the numbers, then you just divide by how many numbers there are. in this case, you would do 64/8 which would then equal 8. then you see how much the numbers differ from the mean. like for your numbers, for 8 it would be 0, for 9 it would be 1, for 7 it would be 1, for 6 it would be 2. you see it? its just how far away it is from the mean. so once you do that, you should have a 6. then you do 6/4 which is 1.5. hope this helps!

Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as old as Ishaan?
Marina86 [1]
The first statement means: 
 
b=i+12,
 
The third statement means:
 
b-3=4(i-3),

b-3=4i-12

b=4i-9

Using the value for b from the first statement in the third statement gives you: 

i+12=4i-9

-3i=-21

i=7:   and since b=i+12

b=19

So Ben is 19 and Ishaan is 7.
