2. what is the solution of the system?
7x + 5y = 19
–7x – 2y = –16

a.(2, 1)
b.(1, 2)
c.(7, 5)
d.(–7, –2)

the answer is b.)

< 1=< 2

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
