Answer: 30792.80
=====================================
Work Shown:
We deposit P = 23400 dollars for t = 7 years, which is compounded n = 1 times per year at an interest rate of r = 4% = 0.04 (we'll use the decimal form of the interest rate)
So this means...
A = P*(1+r/n)^(n*t)
A = 23400*(1+0.04/1)^(1*7)
A = 23400*(1+0.04)^(7)
A = 23400*(1.04)^(7)
A = 23400*1.31593177923584
A = 30792.8036341187
A = 30792.80
Answer:
—Section 1–
a) 5 points. (Points are the dots, there are 5.)
b) 2 lines. (Line a, line b.)
c) Just 1. (that 2D shape in the background.)
d) VWX (V is in the name.)
e) Point W is the intersection. (Both lines meet at that point, they intersect.)
f) YWZ or ZWY both works (Name the line by its points.)
g) XWZ, XWY, ZWV, etc. (Any 3 points that don’t go in a straight line).
h) YWV, ZWV, YXW, etc. (Any 3 points that are within the same plane.)
—Section 2–
a) 9 points.
b) 3 lines.

Answer:
value of x is 22°
Step-by-step explanation:
It is 22 degrees because it is originally a right angle which is 90°. If you do 90-68 you would get 22. The reason you would subtract is because 68 is already used of the 90° angle. My explanation isn't that good.
The second option: The student should have distributed and written -2x+5, not -2x-5.
That’s because the two negatives make a positive when multiplying/distributing.
