PLEASE HELP!!!

Part A:
I have attached the graph of this system of inequalities.

Part B:
Plug in (8,10) into both equations

10 > 3(8) + 10
10 > 24 + 10
10 > 34

This is false!

10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7

This is also false!

So, (8,10) is not included in the solution area for the system.

Write an expression that would calculated the value of the following account after 14 years: $8100 is invested at an APR of 4.8%

Blizzard [7]

Answer:

$8100·1.024^28

Step-by-step explanation:

The future value formula is ...

FV = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded and t is the number of years. Putting the given numbers in place of the corresponding variables gives the expression you want:

FV = $8100(1 +.048/2)^(2·14)

FV = $8100·1.024^28 . . . . . simplified
