Answer:
10.7
Step-by-step explanation:
You set up the proportion like this:

When you solve for x you get

x=10.7 rounded to the nearest tenth
Answer:
After 12 years the investment will be worth $5145.
Step-by-step explanation:
The formula used for compounded interest is:
A = P(1+r/n)^nt
where,
A = future value
P = Principal Amount
r = interest rate
n = no of times interest is compounded
t = time
In the question given:
A=?
P = $2100
r = 7.75% or 0.0775
n = 1
t= 12
A= 2100*(1+0.0775/1)^1*12
A= 2100 *(1+0.0775)^12
A= 2100 *(1.0775)^12
A= 2100 * 2.45
A= 5145
So, after 12 years the investment will be worth $5145.
It is point slope
y-y1 = m(x-x1)
y1 = 2, m = -1, x1 = -3
Make it into slope intercept
Y = -1x + b
2 = 3 + b, b = -1
Y = -1x - 1
Find three points
(-3, 2), (-1, 0), (0, -1)
Now plot these points and draw a line through them
Answer:free points
