Since no base is stated, assume base 10
remember
loga-logb=log(a/b)
also
translates to
and log(a^z)=zlog(a)
log25x-log5=2 means
translates to
simplies to
translates to
expands to
100=5x
divide both sides by 5
20=x
Answer:
D
Step-by-step explanation:
If 2 tangents are drawn to a circle from the same external point then they are congruent.
AG and AE are tangents to the circle from the same external point, thus
AG is congruent to AE
Answer: 
Step-by-step explanation:
Let x be the price. 20% (0.20) 7.25% (0.0725)
We have been given a function 
. We are asked to choose the point from given choices, which is not a solution of given function.
Let us check each given point one by one.
A. (3,9)
Since both sides of function are equal, therefore, point (3,9) is the solution of our given function.
B. 
Since both sides of function are equal, therefore, point is the solution of our given function.
C. 
Since both sides of function are equal, therefore, point is the solution of our given function.
D. 
Since both sides of function are not equal, therefore, point is not a solution of our given function and option D is the correct choice.
