4. Simplify the expression
-22f+8f-15+9

-22f+8f-15+9

-14f-6

-2(7f+3)

-14f -6

Step-by-step explanation:

Add the numbers  

-2 2 + 8 − 1 5 + 9

− 2 2 + 8 − 6

Combine like terms

− 2 2 + 8 − 6

− 1 4 − 6

Solution

− 1 4 − 6

hope this helped :)

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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
