The expression would be > 0.
Subtracting a negative is the same as adding a positive; therefore -18--18 = -18+18 = 0. Since we know that x>-18, 0 is below anything we could get from this.
The general Formula for a decreasing Annuity is:
![P = ( \frac{(1+i)^n -1}{i (1+i)^n}) R](https://tex.z-dn.net/?f=P%20%3D%20%28%20%5Cfrac%7B%281%2Bi%29%5En%20-1%7D%7Bi%20%281%2Bi%29%5En%7D%29%20R%20)
For this example we have:
P = 78,000
n = 7*4 = 28
i = 8%/4 = 2% = 0.02
After substituting you can find value for R, rent.
Answer:
z = 66
Step-by-step explanation:
QT is a midsegment. Thus, applying the midsegment theorem:
RS = 2(QT)
QT = z - 33,
RS = z
Plug in the values into the equation
z = 2(z - 33)
z = 2z - 66
Subtract 2z from each side
z - 2z = -66
-z = -66
Divide both sides by -1
z = 66
Yes it is the most simplified version
