Answer:
Step-by-step explanation:
Let
x ---> the number of years
y ---> the amount in the account balance
Plan A
we have a linear equation of the form
where
The slope is equal to
The y-intercept or initial value is
substitute
For x=10 years
substitute
Plan B
we have a exponential growth function of the form
where
substitute
For x=10 years
substitute
Find the difference of the two account balances after 10 years
Answer: well we need to see a visual representation of figure 1 and figure 2
Answer: 3rd graph
Explanation: In order to determine which graph shows a downward or negative slope, we need to be able to look at each of the graphs and determine which line is decreasing when going from left to right.
Notice that the 3rd graph is the only graph with a downward
or negative slope which means that this is our answer.
The answer is $660 because when multiply 3000•.22=$660.
