Answer:
5)
<2 = 79°
<1 = 101°
<3 = 101°
6)
x = 5
y = 3
Step-by-step explanation:
5)
<2 = 79°
<1 = <3 = 180 - 79 = 101°
6)
4y - 6 = 2y
2y = 6
y = 3
2x + 4 = x + 9
x = 5
Answer:
(1.5,1)
Step-by-step explanation:
I don't know how to explain. I used GeoGebra and I put the coordinate down and then made lines. Line AC and line BD. Then I put a point on where it intersects and it comes out to (1.5,1). You can also use distance formula, but that is more work.

Step-by-step explanation:
<h3>Answer: 787.25 dollars</h3>
=============================
Work Shown:
A = final amount after t years = 1000
P = initial deposit = unknown
r = interest rate in decimal form = 0.08
n = compounding frequency = 12
t = number of years = 3
-----
A = P*(1+r/n)^(n*t) is the compound interest formula
1000 = P*(1+0.08/12)^(12*3)
1000 = P*1.27023705162066
1.27023705162066P = 1000
P = 1000/1.27023705162066
P = 787.254629932364
P = 787.25 rounding to the nearest penny
----
note: this assumes that the interest rate stays at 8% the entire three year period; also, you cannot withdraw any money from the account during this time period.
