Answer:After 9 years:
7,680
Step-by-step explanation:
4%=0.04
1 year = 12,000 x 0.04=<u>480</u>
9 years= 480 x 9 = <u>4320</u>
12,000-4320=<u> 7,680</u>
8.35x-1.5=71.98
Add 1.5 to both sides:
8.35x=73.48
Divide both sides by 8.35:
x=8.8
1. all functions are relations.
2.
-7 + 3(-12) ÷ (-3)
-7 - 36 ÷ -3
-7 - (-12)
-7 + 12
5
3.
f(n) = n² - n f(-4)
f(-4) = -4² - (-4)
f(-4) = 16 - (-4)
f(-4) = 16 + 4
f(-4) = 20
hope this helped, God bless!
