399,499.
Since we are rounding to the nearest thousand, we are going to be focusing on mainly 39(9,499). The rule I learned is, "5 or above, give it a shove". Since it isn't 500 or above, we have to round it down to 9,000.
The total is 399,000.
Answer:
C 2x^2 + 3/2x -5
Step-by-step explanation:
f(x)=x/2-2
g(x)=2x^2+x-3
(f+g) (x)=x/2-2+2x^2+x-3
Combine like terms
2x^2 + 3/2x -5
