Remember some simle log rules
loga+logb=log(ab)
xloga=loga^x
means 
also, if no base is stated, assume base 10
so
log(2x)=-1 is base 10 and translates to
10^-1=2x
1/10=2x
divide both sides by 2 aka times 1/2
1/20=x
3log(2)+log(x)=3
log(2^3)+log(x)=3
log(8)+log(x)=3
log(8x)=3
base 10
10^3=8x
1000=8x
divide both sides by 8
x=125

Answer:
The vertex is:
Step-by-step explanation:
First solve the equation for the variable y
Add 4y on both sides of the equation
Notice that now the equation has the general form of a parabola
In this case
Add and subtract
on the right side of the equation
Factor the expression that is inside the parentheses
Divide both sides of the equality between 4
For an equation of the form
the vertex is: (h, k)
In this case
the vertex is:
