Answer: Choice B) -3
------------------------------------------------------
Work Shown:
f(x) = (x+2)/2
f(-8) = (-8+2)/2 ... replace every x with -8; use PEMDAS
f(-8) = (-6)/2
f(-8) = -3
The answer is true because 8 times 125 (8x125) is equal to 1000 therefore Tiara is correct
3% is the interest so you would do 3% of the investment plus the original investment so 3%×I=z and then z+I=the answer. sorry if this didnt help I'm new and I tried my best sorry!
