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

Answer:

Step-by-step explanation:
x=140°
m || n
Common factors are 1,2,4 so the greatest one would be 4
Divide 7 by 49 which would be 7 then add two to each cabin
All percents are not whole. And no whole number can be rational, because a ration is a piece of, not a whole. I hope this helped!
