F n and m are integers and n2 m2 is even, which of the following is impossible?

Answers

Answer 1

Answer: So, I think that you mean that

n²+m² is even? (the "plus" sign is missing, but I think this is correct).

this can only happen if either:

both n and m are even
or
both n and m are odd

That's because a sum of two expressions is even if either both or none of the expressions summed is even, and a power of a number is even only if the number is even too.

are those some of the options?

yes!
n and m are even,- possible!
n and m are odd, -possible!
n+m is even, - possible; it would be the case if either both n and m are even or both n and m are odd n+m is odd,

so the option we'll choose is:

none of these are impossible

describe what you can do when solving an inequality to assure that the coefficient of the variable term will be positive

Answers

If the coefficient is positive, then just multiply or divide by the same coefficient.
2X less than or equal to 8
divide by 2 throughout to get X is less than or equal to 4

If the coefficient is negative, then multiply or divide by the negative sign and the same number throughout
-2X is less than or equal to 8
divide by -2 throughout to get
X is GREATER THAN OR EQUAL to 8.
Remember the sign changes when you divide or multiply by negative.

0 A public beach in Arkansas charges non- residents $12 per day for a fishing license and $3.50 per day for live bait. Arkansas residents pay an annual fee of $174 plus $1 per day for live bait. How many days must both a resident and a non- resident use the beach in one year so that both pay the same amount? State whether the equation has one solution, no solution or infinitely many solutions. How do you know?

Answers

Non Residents:
f(x)= money in $ paid.
x=number of days.

f(x)=x(12+3.5)=15.5 x

f(x)=15.5x

Arkansas residents
f(x)=money in $ paid.
x=number of days.

f(X)=x+174

Now, we equate functions:

15.5x=x+174 (this is the equation)
15.5x-x=174
14.5x=174
x=174 / 14.5=12

Answer: the number of days is 12 days. The ecuation has one solution, because when I has solved it, I have had one solution.

How can you tell if an equal share is more than one whole ?

Answers

You can tell that the equal share is more than 1 whole when the numerator is greater than the denominator.How? As we all know that in order to convert a fraction to a decimal number, we need to divide the numerator by the denominator.Now, if the numerator is less than the denominator, expect that the digit is now less than 1 whole. But if the numerator is greater than the denominator, for sure, it is more than 1 whole for example.=> 5/4 , where 5 is the numerator and 4 is the denominator=> 1 and 1/4 or 1.25
