Answer:
x=40
Step-by-step explanation:
x=4(x+10)÷5
x=(4x+40)÷5
5x=4x+40
x=40
We have a piecewise function.
Therefore, to find the function, we must evaluate each domain separately.
We have then:
For :
The function for this domain is:
For :
The function for this domain is:
Where,
Substituting:
For :
The function for this domain is:
The first two were negative integers and the quotient is therefor a positive integer (Two negatives equal a positive)
for the implicit integration I got:
the vertical tangent would at points at which y' goes to infinity.
that happen when the right-hand side has singularities, that is, the denominator is 0:
so the two points y above have a vertical tangent.
It is rotated 180 degrees, and it doesn't matter wether clockwise or counterclockwise. 180 degrees results in the same thing both ways
