PLEASE ANSWER ASAP! IMPORTANT! MUST BE CORRECT! GIVING OUT POINTS!John stated that when you add an even and an odd integer the answer will be odd. Use these numbers to answer the questions: –13, –8, 16, 23, –7
Is John’s statement always true, sometimes true, or always false? Write two equations to support your answer.

an odd is 1 more than an even so 2n+1 is odd
so even+odd=2n+2n+1=4n+1=
we see 2 2n's in there which are even
(even)+(even)+1
we know that even+even=even try that withe any 2 even numbers
then +1 means it's odd so therefor it is always true
-13 +16 = 3 odd+even = odd
-7 + 16 = 9
how about -13 + -7 = -20
-8 + 16 = 8
It looks like
even + even = even
odd + odd = even
even + odd = odd
So, we only get an odd result in this case. It seems that it is always true.

Because one side of the square is 8 (4*2), we know that the square's area is 64.
Now, we basically find the circle's area:
A=πr2 = 50.27
64 - 50.27 = 13.73
The area of the shaded region is 13.73

Step-by-step explanation:
4x+3y=17
3x+2y=13
So elimination sounds fun but we will have to do manipulation:
Multiply top equation by 2 and bottom equation by 3. This will cause the second term in both by 6y which means we would be setup for elimination.
8x+6y=34
9x+6y=39
--------------------now subtract the equations
-x+0=-5
So x=5
Now plug it into either question (no matter which-pick and choose)
I will go with the second original 3x+2y=13
So if x=5 we have 15+2y=13
Subtract 15 on both sides: 2y=-2
Now divide both sides by 2: y=-1

Answer:
The value of impulse is 9 N-s.
Step-by-step explanation:
The momentum vs time graph shows the impulse
Impulse :
Impulse is the product of force and time.
In mathematical terms,
Where, F = force
t = time
According to graph,
Impulse=total area
Hence, The value of impulse is 9 N-s.
Answer:
try 12 Newton seconds
Step-by-step explanation:
I think it's going to be 12 because if you find the slope of the first line you get 1 Newton and the slope of the second line is -1 Newton's. so that means there is a change of -2 newtons. so if you multiply -2 Newton's by the 6 seconds you -12 Newton seconds. let me know if this is correct as it's been a while since I've done this type of stuff.
