Variables that are the same are added so 4a and 2a are added making it 6a. Now you have 13+6a=3a+1. Now you have to move things. Move the 3a to the other side making it a negative. So now you have 13+6a-3a=1. You now have 13+3a=1. So move the 13 to the other side. 3a=13-1. Which makes 3a=12. All you have to do now is 12 divided by 3. So a=4
Answer:
We say that a function is increasing on an interval if the function values increase as the input values increase ...
Step-by-step explanation:
For
|a|<b
assume
-b<a<b
so
add 5 to both side
|-2-8x|<66
assume
-66<-2-8x<66
add 2 to both sides
-64<-8x<68
divide everyboy by -8, don't forget to flip sign
8>x>-8.5
-8.5<x<8
the solution is all numbers between -8.5 and 8, not including -8.5 and 8
in interval notation: (-8.5,8)
or
S={x|-8.5<x<8}

Hope it helps u
Step-by-step explanation:
y∝ x
y=k*x
k=y/x
now putt the first point x=8 and y=2
we get k=2/8 =1/4
and also putt 2nd point ,
x=16,y=4 we get k=1/4 and similarly for 3rd and 4th point we also get k=1/4
hence the direct variation , equation become for all is same, that is
y=(1/4)x
