We are given with the following vertices:
A (0,0)
B (-1,1)
C(6,1)
D (2.0)
Next is to plot the vertices in the Cartesian plane so that we can identify the figure. See attached image.
The identified shape is a "Parallelogram".
Answer: Answer for 27 , It dropped 38 feet, (down) so -38 feet
Answer for 28, The difference between 4 and -7 is 11
Step-by-step explanation:
25 + 13 = 38 (but it was going down so its negative)
4 + 7 = 11
Given:
Principal = $14850
Rate of interest = 4% compounded semiannually.
Time = 3 years
To find:
The amount after 3 years.
Solution:
Formula for amount is:
Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded and t is the number of years.
The interest is compounded semiannually, so n=2.
Putting 
in the above formula, we get
On further simplification, we get
Therefore, the amount in the account after three years is $16723.51.
Oh god this one got me too it’s 2
Answer:
7b = 10
Step-by-step explanation:
We have that:
5a + 2b = 0
a is two less than b
So a = b - 2.
Replacing in the above equation:
7b
7b = 10
