Answer:
14/13
Step-by-step explanation:
19/13-5/13=14/13
Since the denominators are the same, you just do the subtraction of the nominators.
The value for n is 
<h3>solving for n</h3>
<u>given data</u>
10n^{2} - 12 = -8
making n the subject of the formula
10n^{2} = -8 + 12
10n^{2} = 4
divide through by 10
n^{2} = 4 / 10
finding the square root of both sides
n = square root ( 4 / 10 )

n = 0.632 or

Answer:
A. 49
Step-by-step explanation:
The average rate of change for the interval ranging from x = 3 to x = 5 for the given function represented in the table above can be calculated using:

x2 = 5
x1 = 3
f(x2) = f(5) = 125
f(x1) = f(3) = 27
Thus,


Average rate of change = 49
Average rate of change of the given table values representing an exponential function is A. 49.
Vertical angles is the answer
Supplementary means they add up to 180
Adjacent means they are next to each other
Complementary means they add up to 90
So the answer is vertical
