46. They are corresponding angles. if you get rid of the line in between 46 and C then youll see that they are on 1 line and corresponding angles are always equal
Option B:
is the correct answer.
Explanation:
The exponential equation is 
If
, then 
Thus, the equation becomes

Applying log rule,
and thus the equation becomes

Since, we know that,
, using this we get,

Hence, the logarithmic equation which is equivalent to the exponential equation
is 
Thus, Option B is the correct answer.
Answer:
113.1
Step-by-step explanation:
A = πr²
A = π (6)²
A = π (36)
A = 113.09 = 113.1
The solving for the first one should be like this

And the next part

After these manipulations just multiply them

And finally you need to square and simplify for the completed answer
Answer:
X = -(146/123) , Y = 21/41
Step-by-step explanation:
2-12x-4y = 32-8y-39x
39x-12x+8y-4y = 32-2
27x+4y = 30
27x+4y-30 = 0
32-8y-39x = 6y-6x
32-8y-6y-39x+6x = 0
-33x-14y+32 = 0
