Answer:

800 to the nearest hundred

Step-by-step explanation:

To Estimate the sum of 405 and 385, we will add 405 together with 385 I.e 405+385 to get 790.

Rounding 790 to a hundred is 800 since the second place value in 790 which is '9' is greater than 5, we will add 1 to the first place which is 7 to give us 8. This will change the second place value to '0' which make the value of 790 to be 800 to a hundred.

Note that 1 can only be added to a preceding value of a number if the succeeding value is greater than 5.

If f(x)=1/x+2 what is f(3+h)?
Wittaler [7]
I don't know if you want the whole x+2 on the bottom or not, but I will put it on the bottom for now.
Replace x with (3+h)

f(3+h)=1/[(3+h)+2]

Now if it's supposed to be JUST x in the denominator...
Replace x with (3+h)

f(3+h)=1/(3+h)+2


Best wishes!
