Answer:
400,000
Step-by-step explanation:
The given sum is 164,215+216,088
We simplify this to get:
164,215+216,088=380,303
The digit at the hundred thousand position is the rightmost 3.
The digit after it is 8.
Since 8≥5 we round up.
We add 1 to 3 to get 4 and replace all digits to the right with zeros.
We round to the nearest hundred thousand to get:
400,000
Answer:
-x^2 +9x -2
Step-by-step explanation:
f(x) = – x^2 + 6x - 1 and g(x) = 3x
- 1,
(f + g)(x) = f(x) + g(x)
= – x^2 + 6x - 1 + 3x
- 1
Combine like terms
= -x^2 +9x -2
