Find the distance between two points -9,-5 and 0,7
Arada [10]
To find the distance, you need to subtract the second point from the first one. So:

0 - (-9) = 9 ( two minuses turn into a positive)

And

7 - (-5) = 12

So the difference between the points is 9 units on the x- axis and 12 on the y-axis.

Hope this helped and pls mark as brainliest!

Im doing this problem where I have to deal with fractions that have variables in them. here is the problem. I linked the picture
AVprozaik [17]
First you should combine n/6-5n/12
that goes to 2n/12-5n/12 which equals -3n/12

then you should cross multiply -3n/12 by 1/16
12(1)=-3n(16)
12=-48n then solve for n by dividing by -48
-12/48=n simplify -1/4=n or -.25=n

16, 4,1,...<br> Find the 6th term
Vlada [557]

Let's see what to do...

_________________________________

Step (1)

Look : 16 , 10 , 4 , ...

It is an arithmetic sequence.

So first we have to find the value of the ratio(( d )) .

To do this, we need to subtract each sentence minus the previous sentence.

So we have : 10 - 16 = - 6

_________________________________

Step (2)

To find the nth sentence in an arithmetic sequence, we must use the following equation :

t(n) = t(1) + (n - 1)d

_________________________________

Step (3)

To find the 6th term just need to put the following parameters in the above sequence.

t(1) = 16 ------ n = 6 ------ d = -6

t(6) = 16 + (6 - 1)( - 6)

t(6) = 16 + (5)( - 6)

t(6) = 16 + ( - 30)

t(6) = 16 - 30

t(6) =  - 14

_________________________________

And we're done.

Thanks for watching buddy good luck.
