Answer:
9
Step-by-step explanation:
First off you need to find the interval that four falls in.
Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one. But four is greater than three and less than ten, so it falls in the second interval.
So, now you can substitute four in for x for the second equation
4^2-7
16-7
=9
Answer:
r = 1/11
Step-by-step explanation:

14r = 3r+1 (combine like terms)
11r = 1
r = 1/11

Answer:
29160cm³
Step-by-step explanation:
(18*18*18) *5 = 29160
Since one knot is 1.15 mph.
We multiply 35 time 1.15, which equals 40.25 mph.
Then we subtract. 175 - 4.25 = 134.75
Round, and you'll get 135mph
Therefore, your answer is 135mph
