Answer:
y - 1 = -3(x - 6)
Step-by-step explanation:
Use the point-slope equation:
y - b = m(x - a)
where the line passes through the point (a, b) and has slope m:
y - 1 = -3(x - 6)
The formula for the future value of the account is
A = P(1 + r/n)^(nt)
where you have
A = 19909.20
P = 8975
r = 0.038
t = 21
The resulting equation is not one that can be solved by algebraic means, but we can use a graphing calculator to find n. This graph shows us n = 12, so
the interest compounds monthly.
You are adding a negative and a positive. It is like subtracting 2.1 from 3.26. Because 2.1 is negative, whenever you add it to a number, you actually subtract. To do this:
3.26 + (-2.1) is like 3.26 - 2.1
3.26 - 2.1 = 1.16
Answer:
( 1, -6 )
Step-by-step explanation:
The solution to the graph is ( 1, -6 ) as that is the point where both equations cross. To double check you can also fill in the equations with the points given and they both should solve.
