Step-by-step explanation:
A = P
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
3178 = 2000(1+.086/2)^2t
t = 5.499904413
Answer:
m = -3
y-intercept = 5
Step-by-step explanation:
You can use the rise/run approach on this graph. You start at the first point, which luckily, is the y-intercept (0, 5).
You can count 3 units down (which gives you the -3) and then 1 unit right (which gives you the 1).
You can now reduce the fraction to -3.
Let's find , which is essentially what the problem is asking, what
corresponds to an output of 2.
Let's solve below:
- Setting up what we know
- Substituting in
for
(I'm not sure if this is the correct expression for
- Subtract 4 from both sides to make a step to isolate
(what we are trying to find)
- Divide both sides of the equation by 23 to isolate
Thus the input is .
