Answer:11
Step-by-step explanation:
5x-6-x+9
When x=2 we have
5(2)-6-2+9
10-6-2+9
10+9-6-2
19-6-2=11
if its diameter is 4 inches, then its radius is half that, or 2 inches.
7 9/12 = 7.75
2 11/12 = 2.917
So we can round both of these up.
7.75 rounds to 8
2.917 rounds to 3
8 + 3 = 11
So the estimated sum is 11.
7 9/12 + 2 11/12 = 10 2/3
So the actual sum is 10 2/3.
The estimated sum is a pretty good estimate to the original number.
Answer:
range: {-27, -11, 5, 25}
Step-by-step explanation:
Evaluating the function for the given domain values gives the range values ...
{-27, -11, 5, 25}
__
For example, 4(-5)-7 = -20-7 = -27.
It's a matter of doing the arithmetic. A spreadsheet or calculator that works with lists can be helpful.
