Step-by-step explanation:
The slope of the line is -4/7.
Let C present amount of change
The expression is C = 50 - d
-3x+6.3=-14.4
-6.3=-6.3
-<u>3x</u>=-<u>20.7</u>
-3 -3
x=6.9
Answer:
Graph B
The graph in the attached figure
Step-by-step explanation:
we have

This is a exponential function
of the form

where
a is the initial value
b is the base
r is the rate
b=1+r
In this problem
a=2 ----> the y-intercept
b=3
so
1+r=3 -----> r=3-1=2 -----> r=200%
so
The y-intercept of the graph is equal to 2
As x increases the value of f(x) increases
therefore
Graph B
