Step-by-step explanation:
-8n +19n= -41+4+17
11n = -20
n = - 20/ 11
n= 1.1818
So I just did a homework page that had something like this on it. I would say D because it is not in between 1 and 10.
Hope this helped :)
The equation for the graph sketched below is 
The given graph is an exponential graph and the standard exponential graph is expressed as 
a is the y-intercept of the graph
(x, y) is any point on the graph.
Given the following from the graph;
a = -3
(x, y) = (1, 1)
Substitute the point and the y-intercept into the formula to have

Get the required exponential equation:
Recall that 

Hence the equation for the graph sketched below is

The slope is 4/3. just use the formula.
Answer:
22 km
Step-by-step explanation:
Well if sides of the triangle are 20 km and 21 km then it has to be 22 km
