Answer:
8x + 13
Step-by-step explanation:
"Like terms" means the same kind of algebraic expression...the 6x and the 2x are "like terms" because they both have an x in them. The 9 and the 4 are both constants, which means they are plain numbers. So 6x and 2x is 8x .
9+4 is 13 just like elementary school.
So all together,
6x + 9 + 2x + 4
6x + 2x + 9 + 4
8x + 13
We can rearrange the terms because the problem has all addition in between the terms.
I assume #3 is 19 because the slope of the line is still the same.
Hope this is right and it helps! I'm not very sure though.

Hello, remember you need to write complete questions in order to get good and exact answers. Here you haven't provided any fractions, so I'll give you my own fractions.
The first fraction is:
![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
The second fraction is:
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
So let's say that difference is:
![\frac{1}{2}-\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D-%5Cfrac%7B1%7D%7B4%7D)
Therefore, the result is:
![\frac{1}{2}-\frac{1}{4}=\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D-%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B1%7D%7B4%7D)
The representation of this problem is shown using the number line below. As you can see, we have written both 1/2 and 1/4 and the difference is also indicated giving the result 1/4. That is, if we walk from 1/4 to 1/2 we'll walk 1/4 units.
Answer:
![y = -8x + 3](https://tex.z-dn.net/?f=y%20%3D%20-8x%20%2B%203)
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
In which m is the slope and b is the y-intercept.
Perpendicular lines:
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to y=1/8x+2
This line has slope ![\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D)
So, for the line we want to find the equation, we have that:
![\frac{m}{8} = -1](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7B8%7D%20%3D%20-1)
![m = -8](https://tex.z-dn.net/?f=m%20%3D%20-8)
So
![y = -8x + b](https://tex.z-dn.net/?f=y%20%3D%20-8x%20%2B%20b)
Find the equation of the line through point (1,−5)
This means that when
. We use this to find b. So:
![y = -8x + b](https://tex.z-dn.net/?f=y%20%3D%20-8x%20%2B%20b)
![-5 = -8 + b](https://tex.z-dn.net/?f=-5%20%3D%20-8%20%2B%20b)
![b = 3](https://tex.z-dn.net/?f=b%20%3D%203)
The equation of the line is:
![y = -8x + 3](https://tex.z-dn.net/?f=y%20%3D%20-8x%20%2B%203)
