The sum is of n and 14 can be written as:
n+14=72
The line of the equation perpendicular to y=5 and cuts through (-5,-7) will be given by
m(x-x1)=y-y1
where m=slope.
from y=0x+5, the slope of the perpendicular line m=0,
thus the equation will be:
0(x--5)=y--7
0=y+7
y=-7
The equation is y=-7
Answer:
The 28% rule states that you should spend 28% or less of your monthly gross income on your mortgage payment (e.g. principal, interest, taxes and insurance). To determine how much you can afford using this rule, multiply your monthly gross income by 28%
70-40= 30
30/2 = 15
40/2= 20
15 x 20 = 300
Since it's paid quarterly, then the yearly interest of 2.8% should be divided by 4.
Since the payment is I/4th of the year, then the number of payment will 4 times more:
A= P(1+i)ⁿ, and for a period of 4, A = P(1+i/4)⁴ⁿ
A=5500(1+0.028/4)⁴ˣ⁴ = 5500(1+0.028/4)¹⁶ = $6149.42 (answer A)
