Answer with Step-by-step explanation:
We are given that n and m are two integers
We have to prove that if n-m is even , then 
is also even.
We know that sum of two odd numbers is even.Sum of an odd number and even number is odd.
Product of an odd number and even number is even.
Case 1.Suppose m and n are both even n=4 , m=2
Case 2.Suppose m odd and n odd
n=9,m=5
Hence, proved.
Answer: The answer is A and D
Step-by-step explanation: If you go through all the problems, just replace "b" with "(4)" into a calculator. For A and D, they both equaled 180.
Answer: -1 3/4
Step-by-step explanation
just add the fractions together :)
(between the -2 and -1 1/2)
Step 1: Find the slope
(y-y)/(x-x) = (8-8)/(9+4) = 0
Step 2: Substitute into the slope intercept equation
y - y = m(x - x)
y - 8 = 0(x - 9)
If the problem just wants plain, slope intercept form, then this is your answer.
If not, y = 8
The total cost is $66.14. Hope this helps.
