Answer:

Step-by-step explanation:
We are finding the equation of the line that coincide with line segment AB.
So, we can find the equation by using points A and B.

Slope of line (m) = 
Since slope = 0, therefore the line is parallel to x-axis.
The equation of line is given by 
where
is slope and
is y-intercept.
So equation of line AB:
where
and 



X = (0 + 8)/2 = 4
<span>y = (0 + 4)/2 = 2 </span>
<span>so midpoint is (4, 2) </span>
we solved it by using mid point formulae
Based on the given information, each shelf can hold 9 books. (27/3 = 9) That means 2 additional shelves will hold 18 books. Add 18 to 36 to find the total, which is 54.
Hope that helped you.
Answer:
Simplifying
logx + -4 = 0
Reorder the terms:
-4 + glox = 0
Solving
-4 + glox = 0
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + glox = 0 + 4
Combine like terms: -4 + 4 = 0
0 + glox = 0 + 4
glox = 0 + 4
Combine like terms: 0 + 4 = 4
glox = 4
Divide each side by 'lox'.
g = 4l-1o-1x-1
Simplifying
g = 4l-1o-1x-1
