Answer:
is in slope intercept form
Step-by-step explanation:
We need to write the equation in slope intercept form
Slope intercept form of the equation is
where m is the slope and b is the y intercept
To get the equation in slope intercept form we need to get y alone
Multiply 1/2 inside the parenthesis
To get y alone , subtract 5 from both sides
is in slope intercept form

Answer:
Step-by-step explanation:
Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula
Here's what we have:
The amount after a certain time that she has in the bank is 4672.12; that's A(t).
The interest rate in decimal form is .18; that's r.
The number of times the interest compounds is 12; that's n
and the time that the money is invested is 3.5 years; that's t.
Filling all that into the formula:
Simplifying it down a bit:
Raise 1.015 to the 42nd power to get
4672.12 = P(1.868847115) and divide to get P alone:
P = 2500.00
She invested $2500.00 initially.
