Answer:
Step-by-step explanation:
Total distance = 3 + 2.5 = 5.5mi/h
Total time = 0.75h + 2hr = 2. 75 hr
Average speed = 5.5 / 2.75 = 2
Answer:
X=7
(x - 3 )(x +5)
(x+3) (x-5)
X - 35
Step-by-step explanation:
(x + 1)2 = 16
Expanding , we have
2x + 2 = 16
2x = 16 - 2
2x = 14
X= 7.
Let
be the smaller integer. The larger integer is then
, and we have






We omit
, since
is negative.
Then for
we find
, but this is not odd.
There are no consecutive odd integers that satisfy the given condition!
You can tell if the equation is linear or not if the equation makes a straight line on a graph.
