Step-by-step explanation:
For every increase in the x-value by 1,
the y-value decreases by -2.
(From 3 to 1 and from 1 to -1)
Hence, slope of line k
= Rise/Run = (-2)/1 = -2. (A)
Answer:
x=8
Step-by-step explanation:
add 4 to both sides
divide 40 by 5
then you are left with x=8
Answer:
![\frac{59}{8} or 7\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B59%7D%7B8%7D%20%20or%207%5Cfrac%7B3%7D%7B8%7D)
Step-by-step explanation:
![\frac{80}{4} - 12\frac{5}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B4%7D%20%20-%2012%5Cfrac%7B5%7D%7B8%7D)
First you need to make the 12 5/8 into an improper fraction by multiplying 12 by 8 and then adding the total by 5.
-> ![\frac{101}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B101%7D%7B8%7D)
Now you have
so you need a common denominator by multiplying the first fraction by 2
![\frac{80}{4} -> \frac{160}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B4%7D%20-%3E%20%5Cfrac%7B160%7D%7B8%7D)
Then you subtract 160 - 101 which equals 59.
![\frac{59}{8} or 7\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B59%7D%7B8%7D%20%20or%207%5Cfrac%7B3%7D%7B8%7D)
